## Abstract

Intangible cultural heritage has a unique value. It is very important to evaluate and discover the value of intangible cultural heritage. Therefore, referring to the relevant references of countries around the world, this paper compares the research status of countries around the world with the development trend of China’s intangible cultural heritage, indicating that the network resources of intangible cultural heritage can be converted into cultural capital according to the basic theory of cultural capital and then get an economic value. The use value of intangible cultural heritage is analyzed and considered according to IPA entity model analysis, kernel density estimation (KDE), and gray correlation calculation (calculated by using IPA analysis conclusion). Among them, because intangible cultural heritage cannot be measured and verified immediately, indirect measurement verification is carried out by selecting indirect indicators such as the total number of intangible cultural heritage and the development trend of intangible cultural heritage tourism. Based on the gray correlation analysis of the total number and relative density of national intangible cultural heritage and the intangible cultural heritage tourism and related industrial chains, the following proposals for the development trend of intangible cultural heritage are clearly put forward as follows: (1) Further excavate the meaning of “non-material property tourism” and increase the scope of development and design of cultural and art tourism network resources. (2) Make full use of the guiding effect of government departments on “intangible cultural heritage tourism,” and improve the normalization of the combination of culture, art, and tourism. (3) Expand the whole industrial chain of “intangible cultural heritage tourism” in an orderly manner, and promote the concept of coordinated and sustainable development of cultural and art tourism.

## 1. Introduction

People’s intangible cultural heritage (hereinafter referred to as intangible cultural heritage) is a unique way of key historical and cultural heritage in the world. It has a particularly key and unique meaning of world history, culture, art, plastic arts, and cultural aesthetics. It is also a precious cultural and artistic capital of global human society. It is the continuation of the spiritual essence of “being” in the history of global human development and the deep imprint of the nation. It is the representative of the national flag and national identity. It is also a symbol of national flag and national identity. Unlike intangible cultural heritage, its detailed existence depends on the initial media created by people and is passed down from generation to generation according to oral tradition. Therefore, scientific research on intangible cultural heritage has key practical significance for both the country and the nation [1].The development and design of intangible cultural heritage is in line with the provisions of the period, the provisions of independent innovation in the transformation and development of intangible cultural heritage and tourism, and the feasibility analysis of exploring “poetry” and “distance” in the collaborative development trend of culture and tourism [2]. Various key intangible spiritual essence historical and cultural heritages are the specific content of rich and excellent corporate culture accumulated and inherited by the Chinese nation in the long-term material production and social life and are the key components of the 5000 year Chinese civilization. Systematic scientific research is carried out according to the style of taking the vast and thick intangible cultural heritage as the theme, integrating a variety of folk culture “intangible property” into the development of tourism resources, and taking this as a breakthrough, collaboration is carried out in the fields of current policies, network resources, sales market, and industrial chain innovation to assist in the maintenance and utilization of intangible cultural heritage, so that we can not only spread, inherit, and sustain Chinese traditional culture, At the same time, it also creates new industrial chains, new development trends, and new driving forces for tourism, and promotes the further coexistence of intangible cultural heritage and tourism. In the new era of “cultural tourism integration,” the cultural tourism industry chain is developing from a new perspective. In the new era of “integration of culture and tourism,” taking “intangible cultural heritage” and “tourism industry” as relevant research objects, this paper deeply ponders the coordination between the inheritance of “intangible cultural heritage” and the independent innovation of holiday tourism. In the new era of “cultural tourism integration,” we take “intangible cultural heritage” and “the tourism industry” as relevant research objects. Considering the inheritance of “intangible cultural heritage” and the shared development of independent innovation of vacation tourism, we are concerned about the traditional cultural extension of “intangible cultural heritage,” the collaborative requirements of independent innovation of vacation tourism, and everyone’s spiritual needs. The optimization, allocation, and reconstruction of cultural tourism network resources are completed according to the complementary methods of continuously infiltrating and expanding the maintenance and utilization of intangible cultural heritage and the reform and innovation of the tourism industry. In accordance with the complementary methods of continuously infiltrating and expanding the maintenance and utilization of intangible cultural heritage and the reform and innovation of the tourism industry, we will improve the allocation and reconstruction of cultural tourism network resources, and basically build a new comprehensive management system with the dual role of promoting intangible cultural heritage and the development trend of tourism development. It is an urgent daily task to explore the independent innovation and integration of “intangible cultural heritage vacation tourism,” reproduce cultural tourism, innovate independently in a modern environment, show the traditional culture to the public, and explore effective ways for the coupling and shared development of intangible cultural heritage and tourism development. This is also an urgent daily task [3].Therefore, this paper discusses the value of intangible cultural heritage through certain research methods to assess the value and index measurement of intangible cultural heritage, which is measured and reflected through the economic value of the tourism industry.


## 2. Research Background

Foreign scholars and experts have explored the two-way relationship between intangible cultural heritage and the tourism industry through different perspectives of positive and negative aspects. On the positive side, researchers analyze and explore through the correlation between the two and their positive influence on each other. In terms of intangible cultural heritage and tourism industry correlation, Nasser explored urban cultural heritage preservation and sustainable tourism development from the perspective of effective correlation and mutual promotion between intangible cultural heritage and the tourism industry [4]. Loulanski et al. argued that intangible cultural heritage and the tourism industry are mutually reinforcing relationships and that the orderly integration of intangible cultural heritage and the tourism industry have sustainable viability [5]. Timothy argued that the mutually supportive development of the cultural heritage sector and the tourism industry are an emerging trend in the integration of contemporary cultural economy [6]. Throsby explores the path of sustainable economic and cultural development by constructing the “golden rule” for the codirectional development of intangible cultural heritage and the tourism industry with relationship building as the main research point [7]. Nega pointed out that management and value evaluation in cultural tourism and intangible cultural heritage are correlated, and they not only support each other but also enhance each other’s value, and they analyzed and studied the case of the Lalibela Ashenda Festival in Ethiopia [8].In domestic theoretical research, scholars and experts have evaluated the relationship between intangible cultural heritage preservation and the tourism industry in both positive and negative directions. In terms of positive effects, Lin argued that in the current context of experience economy, tourism experience of intangible cultural heritage as an interactive model is an effective path for intangible cultural heritage preservation and leisure tourism development [9]. Wang proposed the concept of “authentic tourism” and believed that the positive interaction between intangible cultural heritage and tourism could help to maximize the satisfaction of the demand and experience value of public tourism [10]. According to Wang, intangible cultural heritage and tourism have a natural relationship, and both intangible cultural heritage and tourism activities are essentially cultural in nature, with tourists pursuing cultural goals and intangible cultural heritage itself being the carrier of culture. The intangible cultural heritage, which is constantly evolving, has its own characteristics, and its new content is the driving force behind the continued vitality of tourism products and businesses. While enriching the content of tourism, it is also an important path to promote the protection and transmission of intangible cultural heritage [11].


## 3. Research Methodology and Materials

### 3.1. Main Theories

#### 3.1.1. Intangible Cultural Heritage

The cultural heritage defined by China and the world can generally be divided into two categories: “tangible” and “intangible” cultural heritage. In the hearts of the vast majority of people, “tangible cultural heritage” is “the chemical species of cultural heritage,” such as precious cultural relics, pottery, and relics [12]. “Intangible cultural heritage” means that there is no entity but not limited to performance, cultural knowledge, and professional ability. According to the form of information, they are divided into “tangible” and “intangible” cultural heritage categories [13]. Tangible cultural heritage refers to movable property mortgage, real estate, and key precious cultural relics in the historical period. Intangible cultural heritage refers to some traditional main forms of material civilization theme activities and forms that exist in a designated intangible form and are in direct contact with everyone’s daily life at that time.The definition of “intangible cultural heritage” (intangible ICH) was introduced into Japan by the last “law on the protection of cultural and artistic assets” implemented worldwide in Japan. Some cultural heritage with no physical shape is called “intangible ICH,” which is a kind of cultural heritage. In October, 2003, the concept of “intangible cultural heritage” was gradually accepted and recognized by people all over the world [14]. At the same time, in order to better understand, the regulations on safeguarding intangible cultural heritage based on UNESCO documents have been implemented. The list of national intangible oral cultural heritage is divided into the following five categories: firstly, oral short stories; secondly, English composition model forms; thirdly, art performance, social development customs, and plastic arts; Fourthly, traditional handicrafts; Fifthly, the understanding and practice of nature. However, due to the different domestic situations, the National Intangible Cultural Heritage Federation has clearly put forward many new opinions on the classification of intangible cultural heritage.The evolution of intangible cultural heritage maintenance [15] is shown in Figure 1.Figure 1
Evolution of the concept of intangible cultural heritage.As shown in Figure2 below, Chinese scholars have two symbolic views on the definition of “intangible cultural heritage:” one thinks that “intangible cultural heritage” includes various traditional Chinese cultural methods, such as folk-themed activities, traditional performing arts, and cultural indoor space; the other thinks that “intangible cultural heritage” includes various traditional Chinese cultural methods, such as folk-themed activities, traditional performing arts, and cultural interior space. Second, “intangible cultural heritage” is a kind of cultural heritage that is spread from generation to generation according to oral and spiritual essence. According to the concept of the national standards of the United Nations Organization for culture, education, science, rationality, and culture and art institutions, and the norms of the opinions and suggestions on strengthening the maintenance of China’s intangible cultural heritage announced and implemented by the former Ministry of culture in 2005, this scholar clearly puts forward the main definitions of intangible cultural heritage, which are a part of the whole process of recording the cultural heritage of relevant communities, groups, institutions, and residents. Special tools, objectives, and venues for the examination of professional knowledge, professional skills, social development and practical skills, and related common sense. The implication category of Chinese national intangible oral cultural heritage works includes the following six property components [16].Figure 2
The scope covered by intangible cultural heritage in China.According to the specific heritage categories contained in the document catalogue of national protected intangible cultural heritage in the current standard classification of Chinese folk intangible cultural heritage, Chinese folk plastic arts can be effectively divided into the following ten categories: folk literature, folk music, folk dance, folk art, traditional handicraft, traditional drama, opera, traditional acrobatic performance activities and athletics, traditional medicine, and folklore. After considering the current research achievements of intangible cultural heritage around the world in an all-round way, many achievements have been made closely around the regulations on safeguarding intangible cultural heritage. After continuous scientific research, with the rapid development of society and the gradual deepening of relevant discussions in countries around the world, people have further enriched and promoted their understanding of the definition and meaning of intangible cultural heritage.


#### 3.1.2. Cultural Capital Theory

In the 1980s, the European sociologist Bourdieu, in the preface chapter of his book “Forms of Capital,” for the first time, creatively reargued and defined a new set of theoretical foundations and theoretically basic material concepts of the category of material capital, “cultural capital” [17]. He thus proposed that material capital in the broad sense that can be subdivided into three main theoretically fundamental material forms: economic capital, cultural capital, and material social capital. Cultural capital can be further divided into the following three main material forms of culture: first, a subjective state of human existence, expressed as a state of mind and a state of spiritual insistence on the meaning of human life; second, a systemic objective state, in which the information material of cultural goods (pictures, books, dictionaries, tools, machines, etc.) with a specific systemic category of content is the objective state (tools, machines, etc.) as an objective basis of a form of information carried out and presented; third, system state information should also all be presented in its entirety in the form of dynamic information describing changes in the objective state of information. Culture itself has a value, and this intangible value can of course be transformed into a tangible economic value. Cultural capital, as objective existence, and subjective economic capital can be unified to form cultural products. The cultural capital in Bourdieu’s theoretical elaboration is the theoretical basis for the productive conservation and industrial development of intangible cultural heritage. On the one hand, cultural capital guides the rational production and consumption activities of people, and on the other hand, it determines the innovation of ideas and the constant adaptation to the changing needs of people. The introduction of Bourdieu’s theory of cultural capital has sparked a hot topic of discussion about culture and its production in the Western academic world. David Crosby, an Australian scholar, explains that, in addition, “cultural capital is the accumulation of cultural values in the form of wealth.” In addition, he himself tries to divide “cultural capital” into “tangible cultural capital” and “intangible cultural capital” [18]. The process of accumulation of tangible resources and tangible cultural capital generally occurs in buildings, sites, art museums, and a large number of other cultural artifacts, such as paintings, sculptures, and many other cultural artifacts that are widely available in the form of their private objects and will eventually be widely attributed with a specific cultural meaning (often referred to as “cultural heritage”). Intangible cultural capital consists of a set of ideas, practices, beliefs, traditions, and values that are consistent with a particular group of people. The important historical and cultural values and their connotations contained in the composition of intangible cultural capital are often in direct correspondence with each other or with other historical and economic values of human beings. For example, the existing rich ancient cultural, musical and artistic texts, modern historical and literary works, the folk wealth and accumulation, cultural customs (habits) and various spiritual beliefs, or various cultural languages, have an extremely direct and extensive deep and lasting political and spiritual cultural value, but often have no direct political and economic value at all, because at times they can no longer be truly valued as a material wealth value to be traded for the social value. However, the various commercial and service activities and product flows associated with these direct flows of material intangible wealth and tangible cultural capital can create a direct cultural value and a potential economic value for society, respectively. The “intangible culture” is an important characteristic and representation of the “intangible culture” part of the “intangible cultural heritage,” as shown in Figure 3.Figure 3
The transformation path of cultural resources into cultural capital.


### 3.2. Research Methodology

#### 3.2.1. IPA Analysis Method

IPA analysis (importance performance analysis) is a method to accurately measure and objectively analyze the intrinsic importance of a specific product characteristic or a specific service content beyond the subjective expectations of customers, and to observe the intrinsic differences between the levels of performance indicators and technical performance. It is a quantitative analysis method to find the possible points to improve productivity or further improve the target customer satisfaction. It was first proposed by Martilla et al. [19]. Evans et al. [20] proposed for the first time in China to formally apply the IPA model and analysis method tool techniques to develop basic research in the field of domestic cultural tourism. In recent years, IPA analysis method tool technology will mainly apply the research work to improve the basic service resources supply and its quality in China’s tourism and the culture industry, the value of tourists’ destination perception experience, tourism service industry destination image value enhancement and other three factors related to the basic comprehensive method research. For example, the National Natural Science Foundation of China Geng [21] project and other items. Based on the perspective of China and ethnic regions, a hypothetical evaluation model was constructed as a Chinese tourism service industry of service and provision of service quality dimension and satisfaction evaluation dimension index differences. Through the empirical questionnaire analysis questionnaire data and IPA data comprehensive analysis, to explore the most specific difference between tourism hotels and services and tourist quality satisfaction difference indicators in the three countries mentioned above different evaluation dimensions data level between the most specific difference cause analysis and difference analysis method importance. The research backbone of the group such as Zunan [22] proposed to study and build up a model system for measuring the customer perception and an experience index of tourism hotel chain B&B based on the research results of hotel B&B tourist perception and the experience evaluation value model, using separate methods such as IPA regression analysis, factor regression analysis, and equal weighting method to investigate the tourist perception between various types of economic tourism hotel chain B&B at home and abroad The quantitative and empirical comparative evaluation of the differences in indicators of experience evaluation was carried out, and a series of tourism-related planning strategies and suggestions for improving the perception indicators of accommodation tourists and destination experience perception indicators were proposed. The project of Jing Xuli et al. research team [23] mainly used the web text analysis model and the IPA model to analyze and compare some subtle cognitive differences based on individual tourists’ overall perception and way perception of cultural image characteristics of the same global tourism route destination, with a view to help China to optimize international tourism and cultural destination image resources for international tourism resources strategy [24].This paper focuses on the valuation and index measurement of intangible cultural heritage using IPA analysis also through the indirect measurement of the tourism value. The measured values are not directly represented in the article but in the calculated values of the gray correlation, which is calculated by IPA analysis. Therefore, this paper emphasizes IPA analysis to fully evaluate and measure the relationship between ICH and the tourism industry and analyze the value of ICH.


#### 3.2.2. Multimodel Combined Coupling Evaluation Method

A three-dimensional evaluation of structural coupling, dynamic coupling, and stage coupling is carried out for the intangible cultural heritage and tourism industry systems by combining multiple models. Based on the gray correlation model, the structural coupling of the two systems is analyzed by the CPA (based on IPA) model; the entropy change model is used to explore the coupling relationship between the two systems in the dynamic development direction; the coupling coordination degree model is used to evaluate the coupling development level of the two systems, and the different spatial and temporal development stages of the coupling are classified. The coupling coordination degree model is used to evaluate the coupling development level of the two systems, and to classify the different development stages of the coupling and the synchronization of the two systems. The path and method of overall coupling evaluation are provided for the empirical research.


### 3.3. Equation Theory

#### 3.3.1. Kernel Density Estimation (KDE)

China’s intangible cultural heritage is starry and huge, but due to the different conditions of different cultural elements, the density of projects in each region is unevenly distributed from the situation of regional excavation and collation declaration, and some regions are still blank areas. Taking the representative national intangible cultural heritage (data source: China’s intangible cultural heritage network) as the measurement object, we try to map the density of national intangible cultural heritage items by Kernel density estimation (KDE), a spatial analysis tool in ArcGIS software, according to the probability theory.Kernel density is defined as: setx1,…,xn the point set is a sample f drawn from the overall of the distribution density f function as, x estimated fx at a point. The Rosenblatt–Parzen kernel estimation is usually used, and its calculation formula is(1)fnx=1nh∑i=1nkx−x1h.In (1), the kx−x1/h formula is the kernel h≻0 function and x−x1 is the broadband, which indicates the distance from the valuation point to the event. The main factors that affect KDE are the mathematical form of the kernel function and the value of the bandwidth.


#### 3.3.2. Gray Correlation Degree Calculation Method

The gray correlation analysis method is used to analyze the gray correlation degree of various intangible and cultural heritage in the tourism service industry and its development with related multi-industries, which can reflect more objectively and truly the gray cross-correlation and relationship between various intangible or cultural heritage and tourism-related industry development and other multi-related industry development. The data are extracted from 2000 to 2009 and from 2010 to 2019. The gray correlation model was constructed by extracting two sets of relevant data (based on the China Intangible Cultural Heritage Tourism Statistical Yearbook and relevant data from the National Bureau of Statistics) from 2000 to 2009 and from 2010 to 2019. The numerical potential of the gray correlation model is based on the IPA analysis method, and the values calculated by the IPA analysis method are used to calculate and analyze the gray correlation degree.xi, m is the selected relevant industry, and n is the time series of the study, where Xi=Xi1,Xi2…,Xik is the data of the selected industry related to tourism.The calculation formula is as follows:(2)xik=xikxi1,k=1,2,…n,i=1,2…m.After normalization, the obtainedxi matrix is(3)xi=xi1,xi2,…,xiki=0,1,2,…,m.Calculate the difference series as(4)△i=△i1,△i2,…,△iki=0,1,2,…,m.Calculate the two extreme differences as(5)M=maximaxk△ik,m=minimink△ik.Calculate the correlation coefficient as(6)γ∂k=m+ζM△ik+ζM,ζ∈0,1,i=1,2,…,i=1,2,…,m.Calculate the gray correlation coefficient as(7)γ∂k=1n∑k=1nγik,i=1,2,…,m.

The important historical and cultural values and their connotations contained in the composition of intangible cultural capital are often in direct correspondence with each other or with other historical and economic values of human beings. For example, the existing rich ancient cultural, musical and artistic texts, modern historical and literary works, the folk wealth and accumulation, cultural customs (habits) and various spiritual beliefs, or various cultural languages, have an extremely direct and extensive deep and lasting political and spiritual cultural value, but often have no direct political and economic value at all, because at times they can no longer be truly valued as a material wealth value to be traded for the social value. However, the various commercial and service activities and product flows associated with these direct flows of material intangible wealth and tangible cultural capital can create a direct cultural value and a potential economic value for society, respectively. The “intangible culture” is an important characteristic and representation of the “intangible culture” part of the “intangible cultural heritage,” as shown in Figure 3.Figure 3
The transformation path of cultural resources into cultural capital.


## 3.2. Research Methodology

### 3.2.1. IPA Analysis Method

IPA analysis (importance performance analysis) is a method to accurately measure and objectively analyze the intrinsic importance of a specific product characteristic or a specific service content beyond the subjective expectations of customers, and to observe the intrinsic differences between the levels of performance indicators and technical performance. It is a quantitative analysis method to find the possible points to improve productivity or further improve the target customer satisfaction. It was first proposed by Martilla et al. [19]. Evans et al. [20] proposed for the first time in China to formally apply the IPA model and analysis method tool techniques to develop basic research in the field of domestic cultural tourism. In recent years, IPA analysis method tool technology will mainly apply the research work to improve the basic service resources supply and its quality in China’s tourism and the culture industry, the value of tourists’ destination perception experience, tourism service industry destination image value enhancement and other three factors related to the basic comprehensive method research. For example, the National Natural Science Foundation of China Geng [21] project and other items. Based on the perspective of China and ethnic regions, a hypothetical evaluation model was constructed as a Chinese tourism service industry of service and provision of service quality dimension and satisfaction evaluation dimension index differences. Through the empirical questionnaire analysis questionnaire data and IPA data comprehensive analysis, to explore the most specific difference between tourism hotels and services and tourist quality satisfaction difference indicators in the three countries mentioned above different evaluation dimensions data level between the most specific difference cause analysis and difference analysis method importance. The research backbone of the group such as Zunan [22] proposed to study and build up a model system for measuring the customer perception and an experience index of tourism hotel chain B&B based on the research results of hotel B&B tourist perception and the experience evaluation value model, using separate methods such as IPA regression analysis, factor regression analysis, and equal weighting method to investigate the tourist perception between various types of economic tourism hotel chain B&B at home and abroad The quantitative and empirical comparative evaluation of the differences in indicators of experience evaluation was carried out, and a series of tourism-related planning strategies and suggestions for improving the perception indicators of accommodation tourists and destination experience perception indicators were proposed. The project of Jing Xuli et al. research team [23] mainly used the web text analysis model and the IPA model to analyze and compare some subtle cognitive differences based on individual tourists’ overall perception and way perception of cultural image characteristics of the same global tourism route destination, with a view to help China to optimize international tourism and cultural destination image resources for international tourism resources strategy [24].This paper focuses on the valuation and index measurement of intangible cultural heritage using IPA analysis also through the indirect measurement of the tourism value. The measured values are not directly represented in the article but in the calculated values of the gray correlation, which is calculated by IPA analysis. Therefore, this paper emphasizes IPA analysis to fully evaluate and measure the relationship between ICH and the tourism industry and analyze the value of ICH.


### 3.2.2. Multimodel Combined Coupling Evaluation Method

A three-dimensional evaluation of structural coupling, dynamic coupling, and stage coupling is carried out for the intangible cultural heritage and tourism industry systems by combining multiple models. Based on the gray correlation model, the structural coupling of the two systems is analyzed by the CPA (based on IPA) model; the entropy change model is used to explore the coupling relationship between the two systems in the dynamic development direction; the coupling coordination degree model is used to evaluate the coupling development level of the two systems, and the different spatial and temporal development stages of the coupling are classified. The coupling coordination degree model is used to evaluate the coupling development level of the two systems, and to classify the different development stages of the coupling and the synchronization of the two systems. The path and method of overall coupling evaluation are provided for the empirical research.

## 3.3. Equation Theory

### 3.3.1. Kernel Density Estimation (KDE)

China’s intangible cultural heritage is starry and huge, but due to the different conditions of different cultural elements, the density of projects in each region is unevenly distributed from the situation of regional excavation and collation declaration, and some regions are still blank areas. Taking the representative national intangible cultural heritage (data source: China’s intangible cultural heritage network) as the measurement object, we try to map the density of national intangible cultural heritage items by Kernel density estimation (KDE), a spatial analysis tool in ArcGIS software, according to the probability theory.Kernel density is defined as: setx1,…,xn the point set is a sample f drawn from the overall of the distribution density f function as, x estimated fx at a point. The Rosenblatt–Parzen kernel estimation is usually used, and its calculation formula is(1)fnx=1nh∑i=1nkx−x1h.In (1), the kx−x1/h formula is the kernel h≻0 function and x−x1 is the broadband, which indicates the distance from the valuation point to the event. The main factors that affect KDE are the mathematical form of the kernel function and the value of the bandwidth.


### 3.3.2. Gray Correlation Degree Calculation Method

The gray correlation analysis method is used to analyze the gray correlation degree of various intangible and cultural heritage in the tourism service industry and its development with related multi-industries, which can reflect more objectively and truly the gray cross-correlation and relationship between various intangible or cultural heritage and tourism-related industry development and other multi-related industry development. The data are extracted from 2000 to 2009 and from 2010 to 2019. The gray correlation model was constructed by extracting two sets of relevant data (based on the China Intangible Cultural Heritage Tourism Statistical Yearbook and relevant data from the National Bureau of Statistics) from 2000 to 2009 and from 2010 to 2019. The numerical potential of the gray correlation model is based on the IPA analysis method, and the values calculated by the IPA analysis method are used to calculate and analyze the gray correlation degree.xi, m is the selected relevant industry, and n is the time series of the study, where Xi=Xi1,Xi2…,Xik is the data of the selected industry related to tourism.The calculation formula is as follows:(2)xik=xikxi1,k=1,2,…n,i=1,2…m.After normalization, the obtainedxi matrix is(3)xi=xi1,xi2,…,xiki=0,1,2,…,m.Calculate the difference series as(4)△i=△i1,△i2,…,△iki=0,1,2,…,m.Calculate the two extreme differences as(5)M=maximaxk△ik,m=minimink△ik.Calculate the correlation coefficient as(6)γ∂k=m+ζM△ik+ζM,ζ∈0,1,i=1,2,…,i=1,2,…,m.Calculate the gray correlation coefficient as(7)γ∂k=1n∑k=1nγik,i=1,2,…,m.

## 4. Results and Discussion

### 4.1. Status of Intangible Cultural Heritage

Intangible cultural heritage, as a part of the excellent Chinese traditional culture, is long-lasting and new, and has great cultural and scientific values. Strengthening the cognition and development of intangible cultural heritage, is the identification of traditional cultural genes and national cultural lineage, as well as the process of awakening people’s cultural self-reflection and enhancing national cultural self-confidence. The protection and development of intangible cultural heritage in China began at the beginning of this century, and although it started late, it is highly valued by the Party and the State as an important cultural work in the new era. China’s intangible cultural heritage has gone through three stages of development: the initial stage (2001–2005), the development stage (2006–2010), and the prosperity stage (2010-present), and the amount of intangible cultural heritage items, the number of certified bearers, and the cultural ecology. The number of items, the number of certified bearers, and the number of protected areas are now at the forefront of the development of intangible cultural heritage in the world. China’s intangible cultural heritage has been transformed from a “grassroots culture” to a national “cultural symbol” and has become a synonym for “national cultural genes.” In 2006 and 2007, the Anhui province published and confirmed the list of the first batch of local representative provincial intangible cultural heritage protection and inheritance projects at the provincial level and the third batch at the county level through China’s third review. In 2011 and 2014, according to the State Council through the Ministry of Engineering and Construction of the State Ministry of Environmental Protection approved the review determined and at the same time confirmed the publication and generation of the third and fourth batches of China’s Anhui two representative national list of the first batch of intangible cultural heritage of the Anhui province. In 2012 and 2018, the State Administration of Cultural Heritage has jointly announced the identification in order to protect the world-wide fourth and fifth batches of two national representative projects of human significant intangible cultural heritage representative techniques and inheritance of regional representative people. Among them, China’s two national major intangible cultural heritage of humanity projects and the cumulative scale of the total number of conservation achievements have been ranked on the world’s first in both successive countries. At this stage, China’s intangible heritage excavation projects have not only shown a prosperous trend but also made certain achievements in productive conservation and application development.As shown in Figure4, as of 2020, the categories of world intangible cultural heritage declared by China have been inscribed by the United Nations on the list of Intangible Cultural Heritage of Humanity with a total of 39 items, which also include 32 items in the international general endangered list and a total of 7 items in the international endangered list for the types of world intangible cultural heritage that urgently need international protection list, thus, China is currently the country with the largest number of intangible heritage Therefore, China is the country with the largest number of masterpieces of intangible heritage. At the same time, China has built a complete four-level protection and a certification system at the national, provincial, municipal, and county (district) levels, and government departments at all levels have been working in parallel to excavate local intangible cultural heritage types of projects with cultural characteristics and a high aesthetic value, with remarkable results. After more than a decade of accumulation, China now has 1,530 national-level intangible cultural heritages, covering 10 intangible cultural heritage categories. Meanwhile, China has 5,219 provincial-level intangible cultural heritages, 10,331 provincial-level intangible cultural heritages, and 72,776 provincial-level intangible cultural heritages at the county (district) level. The number of intangible cultural heritage at all levels is among the highest in the world.Figure 4
Development of various types of national intangible cultural heritage projects in China.As shown in Figure5, on the basis of the ten categories of intangible cultural heritage, as of December 2020, the Ministry of Culture’s Office of the Special Working Group of the Ministry of Culture of China (now renamed the Ministry of Culture and Tourism) was established to date has initially identified a total of approximately 3,068 people as the main inheritors and representative persons of the representative units of the first five major batches of projects at the national level or major categories of intangible cultural heritage projects. In addition, in China this year, other provinces and municipalities across the country have announced or recognized a total of about 14,928 local municipalities and counties below the level of representative skills excellent inheritors of intangible cultural heritage, together building a genealogy of Chinese cultural heritage. From 2015, the field of culture and tourism, the implementation of “China’s intangible cultural heritage inheritance of population training program,” the use of academic and teaching resources to support, focusing on minority areas and remote and poor areas, in the inheritance of traditional process to carry out “strong foundation,” and broaden their horizons increase. The program focuses on ethnic minority areas and remote and poor areas to “strengthen the foundation,” broaden horizons, and increase knowledge in the process of passing down traditions. At the same time, the inheritors are included in traditional craft workstations and workshops of “intangible cultural heritage,” and the enthusiasm, initiative, and creativity of the inheritors are continuously mobilized. According to statistics, by the end of 2020, 121 institutions across the country, in which the research and training programs are held, have held a total of more than 850 training sessions of various types, and more than 33,000 participants have been trained, in addition to the content of local regions and related forms of extended training, a total of more than 100,000 people covering the group of inheritors.Figure 5
The recognition of representative inheritors of various types of intangible cultural heritage at the national level in China.As shown in Figure6, China, based on its own national conditions, has creatively taken the representative “intangible cultural heritage” as the core, with the purpose of reshaping the cultural system and the soil of “intangible cultural heritage” as the core. At the same time, 168 provincial-level cultural ecological protection zones have been established, including Zulu culture, Anqing theater culture, Sli County woodblock printing culture, Zhangnan traditional cotton weaving technique culture, and Jiangyan Qingming custom culture. China’s national and provincial cultural ecological reserves show a benign trend of year-on-year growth. China has become one of the countries with the largest number of cultural ecological reserves and the largest area in the world.Figure 6

### 4.2. Related Conclusions

#### 4.2.1. Schematic Diagram of the Distribution Number and Density of National Intangible Cultural Heritage

China’s intangible cultural heritage is splendid and huge, but because the situation varies from one cultural element to another, the density of projects in each region is unevenly distributed from the situation of regional excavation and collation declaration, and some regions are still blank areas. Taking the representative national-level intangible cultural heritage (data source: China Intangible Cultural Heritage Network) as the measurement object, we tried to map the density of national-level intangible cultural heritage items through the Kernel density estimation (KDE) method of the spatial analysis tool in ArcGIS software according to the probability theory. The distribution number and density of national-level intangible cultural heritage are schematically shown in Figure7.Figure 7
Schematic diagram of the distribution quantity and density of national-level intangible cultural heritage.


#### 4.2.2. Gray Correlation between the Intangible Cultural Heritage Tourism Industry and Related Industries

As shown in Figure8, based on the IPA model analysis method, this paper obtains the gray correlation degree between each industry and the intangible cultural heritage tourism industry in two stages from 2000 to 2009 and from 2010 to 2019 by calculating the absolute difference and the time series correlation coefficient. It can be seen that the association density of the traditional type of closely related industries has been increasing, with the restaurant industry increasing from 0.6714 to 0.9815, the association of the accommodation industry increasing from 0.6404 to 0.9191, the transportation industry increasing from 0.5709 to 0.9264, and the landscape industry increasing from 0.7295 to 0.8595. At the same time, the original low degree of association with the intangible cultural heritage tourism industry, with the tourism industry associated with the expansion of the boundaries of the close degree is also gradually strengthened, such as with the continuous construction of tourism services and infrastructure, tourism and construction industry association from 0.7305 to 0.8399 along with the rise of new business models, such as agricultural tourism, rural tourism, and tourism and agriculture between the gray. The correlation between tourism and agriculture increased from 0.6589 to 0.9402 with the proposal and development of the national cultural tourism integration plan, the correlation between tourism and culture and the art industry also increased from 0.7926 to 0.9427, and the effect of tourism linking multiple industries became increasingly obvious, and gradually formed a positive interaction between industries.Figure 8

### 4.3. Suggestions for Coupling Development of Intangible Cultural Heritage and the Tourism Industry Are Discussed

#### 4.3.1. Deeply Excavate the Connotation of “Intangible Cultural Heritage + Tourism” and Increase the Development of Cultural and Tourism Resources

Based on the analysis of the above empirical results, the coupled and coordinated development should be promoted on the basis of the integration and joint development of the resources of “intangible cultural heritage + tourism,” and the image of cultural tourism should be enhanced through the deep excavation of the connotation of “intangible cultural heritage + tourism.” To further explore the connotation and related contents of intangible cultural heritage and tourism common source in each local area, and to explore the “meaning” behind the connotation and cultural lineage, is an important link between intangible cultural heritage and tourism industry resources linkage and effective synergy. The development of “ICH + tourism” products in China is an important means for cultural tourism products to achieve differentiation and gain competitive advantage, and also an inexhaustible source for cultural tourism products to further enhance their core competitiveness.At the overall regional level, China’s “intangible cultural heritage plus tourism industry” has great economic and cultural potential; however, cultural tourism lags far behind the high level of economic development, and intangible cultural tourism resources have not been effectively developed and utilized. “The synergistic effect of “1 + 1>2” resources has not yet been formed. According to the evaluation of the correlation of system coupling in this study, the correlation between “intangible cultural heritage” and the tourism comprehensive development system is strong, and the foundation of the combination of the two systems is stable. Most of the intangible cultural heritage areas in China are connected to each other by mountains and rivers, with similar customs, and the cultural and tourism resources share the same root and attributes. Many areas are not only places of interest but also places where “intangible cultural heritage” projects originate and are discovered. Therefore, to strengthen the theoretical exploration of the protection of the connotation of “intangible cultural heritage + tourism” scenic resources is a major historical task for China to realize the coordinated and sustainable development of intangible oral cultural heritage and related tourism resource industries in each region. From a perspective of promoting the combination of intangible cultural heritage inheritance and mass tourism activities, it is a study to enhance the distinctive characteristics of modern tourism cultural product development and improve the innovative quality of mass tourism consumer product development by deeply excavating the profound connotation of China’s intangible cultural traditions and infusing such intangible cultural elements into modern tourism and leisure product development. Culture and tourism consumption products market to maintain a strong sustainable development of attractive and effective two main effective way; from the ancient city tourism culture combined with the protection of non-heritage. Huaihai tourism economic zone planning should pay attention to the protection of ancient cities and towns, ecological and leisure tourism and scenic tourism development, and drive the protection of local characteristics of cultural resources tourism area of reasonable development, through the effective combination of material culture, non-material culture, and natural ecological culture, and enhance the competitiveness of regional cultural tourism.


#### 4.3.2. Give Full Play to the “Non-Physical Heritage + Tourism” Government Guidance, and Improve the Long-Term Mechanism of Cultural Tourism Integration

Based on the evaluation of the empirical results and the benchmarking of each element index, it is necessary to give full play to the role of the government, carry out overall planning, and improve the long-term mechanism for the effective integration of “intangible heritage + tourism.” Government guidance and improvement of mechanism are the top-level guarantee for the coordinated development of intangible cultural heritage and the tourism industry. The synergy of “ICH + tourism” in China is a systematic work involving multiple departments and fields, which requires government departments to stand at the height of the strategic overall situation, carry out scientific planning with advanced concepts, build a long-term mechanism for the integration of culture and tourism, and promote the regional “ICH + tourism” in-depth synergistic development. We should make full use of the guidance of local governments, form a coordinated and unified promotion mechanism of relevant departments, and build a development idea and long-term mechanism of “policy support, protection priority, market operation, and cultural tourism synergy.”On the premise of the mechanism and important guarantee for the coordinated development of intangible cultural heritage and tourism industry, local governments should establish a breakthrough in the “intangible + tourism development model” in terms of institutional mechanisms, policies and standards, taking into account the specific situation of China, and provide a sustainable development direction for “intangible + tourism navigation and backup protection”. The first is to strengthen organizational leadership and improve the institutional mechanism of integrated development of culture and tourism. To establish a leading group for the development of “intangible heritage + tourism,” strengthen the style and effectiveness of government departments, to establish a sound communication and liaison mechanism, to improve the performance assessment and incentive mechanism, and to give full play to the guiding role of government departments in the development of “intangible heritage + tourism.” The second is to strengthen planning and design, and develop action plans and specific programs for the integration of cultural tourism. Adhering to the concept of advanced planning, standing in the height of an industrial layout, the development of “intangible cultural heritage + tourism” involves a number of departments and areas of overall planning and strategic deployment, the development of corresponding planning design and action plans to promote the implementation of related work. The third is to improve the policy system and establish the ICH + tourism development model. The government has introduced special policies for the integrated development of the cultural industry and the tourism industry in terms of finance, finance, talents and land, supported the development with comprehensive policies, reasonably planned the secondary distribution of funds by cultural and tourism bureaus in various cities, provided strong guarantee for promoting the development of “intangible cultural heritage + tourism,” and formulated the “intangible cultural heritage + tourism” demonstration project selection system. The “non-foreign heritage + tourism” demonstration project selection system is formulated, and policy tilts are given to high-quality projects and high-growth enterprises to create regional “non-foreign heritage + tourism” benchmark projects and play a demonstration and a leading role [19].


#### 4.3.3. Expand the Industrial Chain of “Non-Foreign Heritage + Tourism” in an Orderly Manner, and Promote the Sustainable Development of Cultural Tourism Synergy

Based on the analysis of the empirical research results, the key indicators and contents are aligned, and the goal is to promote the effective synergistic development of the industrial economy of the two systems with the coupled and coordinated development of “non-heritage + tourism,” which requires the extension of the industrial chain of cultural and tourism integration. The complete industrial chain shows the coordinated and healthy development of the “NRM + tourism” industry. To further promote the innovation and synergy of culture and tourism, we need to build an industrial chain as the framework support. Based on the attributes of the multifaceted linkage of “NRM + tourism,” we can effectively drive the linkage of regional industries, expand the industrial chain of “NRM + tourism” in an orderly manner, give full play to the correlation of culture and tourism industries, and promote the sustainable development of “NRM + tourism.” It is an effective path to ensure the high-quality and coordinated development of China’s intangible cultural heritage and the tourism industry [25].In the analysis of China’s economic factors industry distribution, categories, upstream and downstream resources relationship, history and other basis, focus on judging the coordinated development of China’s economy, the status and role of the “invisible + tourism” industry, and the time, from the actual starting point and Wenxing travel, Wenxing travel, special cultural tourism, not only can extend the “invisible + travel” tourism industry chain, cultivate new tourism economic growth points but also allow more foreign tourists to understand China’ s history and culture, expand the influence, attractiveness, and competitiveness of culture. Linking the local economic zone “intangible + tourism” characteristics of resources, cultural tourism around the building area performing arts, catering tourism, leisure, night market subdivision to form a full industry chain, such as ecological experience, to enhance the “intangible + tourism” travel, product quality improvement, innovation “cultural tourism industry chain+,” cultivate “non-material learning tourism,” “non-material recreation tourism” and other new economic growth points. We continuously strengthen the chain extension and realize the complementary advantages and strong combination of “intangible cultural heritage + tourism” industry chain with China’s economic zone. We insist on relying on the dual advantages of natural ecology and humanities and history, complementing and strengthening the “intangible cultural heritage + tourism” industry chain, which is a scarce link between ecological experience and historical heritage in China’s economic zone with superior natural conditions and unique regional culture, and promoting the differentiated development of cultural tourism industry. We will take the initiative to coordinate all parties, coordinate consideration, planning and promotion, deeply integrate into the cultural tourism industry chain, and create a number of “intangible cultural heritage + tourism” industry clusters with distinct advantages, high-end cutting, and chain connection.

At the same time, China has built a complete four-level protection and a certification system at the national, provincial, municipal, and county (district) levels, and government departments at all levels have been working in parallel to excavate local intangible cultural heritage types of projects with cultural characteristics and a high aesthetic value, with remarkable results. After more than a decade of accumulation, China now has 1,530 national-level intangible cultural heritages, covering 10 intangible cultural heritage categories. Meanwhile, China has 5,219 provincial-level intangible cultural heritages, 10,331 provincial-level intangible cultural heritages, and 72,776 provincial-level intangible cultural heritages at the county (district) level. The number of intangible cultural heritage at all levels is among the highest in the world.Figure 4
Development of various types of national intangible cultural heritage projects in China.As shown in Figure5, on the basis of the ten categories of intangible cultural heritage, as of December 2020, the Ministry of Culture’s Office of the Special Working Group of the Ministry of Culture of China (now renamed the Ministry of Culture and Tourism) was established to date has initially identified a total of approximately 3,068 people as the main inheritors and representative persons of the representative units of the first five major batches of projects at the national level or major categories of intangible cultural heritage projects. In addition, in China this year, other provinces and municipalities across the country have announced or recognized a total of about 14,928 local municipalities and counties below the level of representative skills excellent inheritors of intangible cultural heritage, together building a genealogy of Chinese cultural heritage. From 2015, the field of culture and tourism, the implementation of “China’s intangible cultural heritage inheritance of population training program,” the use of academic and teaching resources to support, focusing on minority areas and remote and poor areas, in the inheritance of traditional process to carry out “strong foundation,” and broaden their horizons increase. The program focuses on ethnic minority areas and remote and poor areas to “strengthen the foundation,” broaden horizons, and increase knowledge in the process of passing down traditions. At the same time, the inheritors are included in traditional craft workstations and workshops of “intangible cultural heritage,” and the enthusiasm, initiative, and creativity of the inheritors are continuously mobilized. According to statistics, by the end of 2020, 121 institutions across the country, in which the research and training programs are held, have held a total of more than 850 training sessions of various types, and more than 33,000 participants have been trained, in addition to the content of local regions and related forms of extended training, a total of more than 100,000 people covering the group of inheritors.Figure 5
The recognition of representative inheritors of various types of intangible cultural heritage at the national level in China.As shown in Figure6, China, based on its own national conditions, has creatively taken the representative “intangible cultural heritage” as the core, with the purpose of reshaping the cultural system and the soil of “intangible cultural heritage” as the core. At the same time, 168 provincial-level cultural ecological protection zones have been established, including Zulu culture, Anqing theater culture, Sli County woodblock printing culture, Zhangnan traditional cotton weaving technique culture, and Jiangyan Qingming custom culture. China’s national and provincial cultural ecological reserves show a benign trend of year-on-year growth. China has become one of the countries with the largest number of cultural ecological reserves and the largest area in the world.Figure 6

## 4.2. Related Conclusions

### 4.2.1. Schematic Diagram of the Distribution Number and Density of National Intangible Cultural Heritage

China’s intangible cultural heritage is splendid and huge, but because the situation varies from one cultural element to another, the density of projects in each region is unevenly distributed from the situation of regional excavation and collation declaration, and some regions are still blank areas. Taking the representative national-level intangible cultural heritage (data source: China Intangible Cultural Heritage Network) as the measurement object, we tried to map the density of national-level intangible cultural heritage items through the Kernel density estimation (KDE) method of the spatial analysis tool in ArcGIS software according to the probability theory. The distribution number and density of national-level intangible cultural heritage are schematically shown in Figure7.Figure 7

### 4.2.2. Gray Correlation between the Intangible Cultural Heritage Tourism Industry and Related Industries

As shown in Figure8, based on the IPA model analysis method, this paper obtains the gray correlation degree between each industry and the intangible cultural heritage tourism industry in two stages from 2000 to 2009 and from 2010 to 2019 by calculating the absolute difference and the time series correlation coefficient. It can be seen that the association density of the traditional type of closely related industries has been increasing, with the restaurant industry increasing from 0.6714 to 0.9815, the association of the accommodation industry increasing from 0.6404 to 0.9191, the transportation industry increasing from 0.5709 to 0.9264, and the landscape industry increasing from 0.7295 to 0.8595. At the same time, the original low degree of association with the intangible cultural heritage tourism industry, with the tourism industry associated with the expansion of the boundaries of the close degree is also gradually strengthened, such as with the continuous construction of tourism services and infrastructure, tourism and construction industry association from 0.7305 to 0.8399 along with the rise of new business models, such as agricultural tourism, rural tourism, and tourism and agriculture between the gray. The correlation between tourism and agriculture increased from 0.6589 to 0.9402 with the proposal and development of the national cultural tourism integration plan, the correlation between tourism and culture and the art industry also increased from 0.7926 to 0.9427, and the effect of tourism linking multiple industries became increasingly obvious, and gradually formed a positive interaction between industries.Figure 8

## 4.3. Suggestions for Coupling Development of Intangible Cultural Heritage and the Tourism Industry Are Discussed

### 4.3.1. Deeply Excavate the Connotation of “Intangible Cultural Heritage + Tourism” and Increase the Development of Cultural and Tourism Resources

Based on the analysis of the above empirical results, the coupled and coordinated development should be promoted on the basis of the integration and joint development of the resources of “intangible cultural heritage + tourism,” and the image of cultural tourism should be enhanced through the deep excavation of the connotation of “intangible cultural heritage + tourism.” To further explore the connotation and related contents of intangible cultural heritage and tourism common source in each local area, and to explore the “meaning” behind the connotation and cultural lineage, is an important link between intangible cultural heritage and tourism industry resources linkage and effective synergy. The development of “ICH + tourism” products in China is an important means for cultural tourism products to achieve differentiation and gain competitive advantage, and also an inexhaustible source for cultural tourism products to further enhance their core competitiveness.At the overall regional level, China’s “intangible cultural heritage plus tourism industry” has great economic and cultural potential; however, cultural tourism lags far behind the high level of economic development, and intangible cultural tourism resources have not been effectively developed and utilized. “The synergistic effect of “1 + 1>2” resources has not yet been formed. According to the evaluation of the correlation of system coupling in this study, the correlation between “intangible cultural heritage” and the tourism comprehensive development system is strong, and the foundation of the combination of the two systems is stable. Most of the intangible cultural heritage areas in China are connected to each other by mountains and rivers, with similar customs, and the cultural and tourism resources share the same root and attributes. Many areas are not only places of interest but also places where “intangible cultural heritage” projects originate and are discovered. Therefore, to strengthen the theoretical exploration of the protection of the connotation of “intangible cultural heritage + tourism” scenic resources is a major historical task for China to realize the coordinated and sustainable development of intangible oral cultural heritage and related tourism resource industries in each region. From a perspective of promoting the combination of intangible cultural heritage inheritance and mass tourism activities, it is a study to enhance the distinctive characteristics of modern tourism cultural product development and improve the innovative quality of mass tourism consumer product development by deeply excavating the profound connotation of China’s intangible cultural traditions and infusing such intangible cultural elements into modern tourism and leisure product development. Culture and tourism consumption products market to maintain a strong sustainable development of attractive and effective two main effective way; from the ancient city tourism culture combined with the protection of non-heritage. Huaihai tourism economic zone planning should pay attention to the protection of ancient cities and towns, ecological and leisure tourism and scenic tourism development, and drive the protection of local characteristics of cultural resources tourism area of reasonable development, through the effective combination of material culture, non-material culture, and natural ecological culture, and enhance the competitiveness of regional cultural tourism.


### 4.3.2. Give Full Play to the “Non-Physical Heritage + Tourism” Government Guidance, and Improve the Long-Term Mechanism of Cultural Tourism Integration

Based on the evaluation of the empirical results and the benchmarking of each element index, it is necessary to give full play to the role of the government, carry out overall planning, and improve the long-term mechanism for the effective integration of “intangible heritage + tourism.” Government guidance and improvement of mechanism are the top-level guarantee for the coordinated development of intangible cultural heritage and the tourism industry. The synergy of “ICH + tourism” in China is a systematic work involving multiple departments and fields, which requires government departments to stand at the height of the strategic overall situation, carry out scientific planning with advanced concepts, build a long-term mechanism for the integration of culture and tourism, and promote the regional “ICH + tourism” in-depth synergistic development. We should make full use of the guidance of local governments, form a coordinated and unified promotion mechanism of relevant departments, and build a development idea and long-term mechanism of “policy support, protection priority, market operation, and cultural tourism synergy.”On the premise of the mechanism and important guarantee for the coordinated development of intangible cultural heritage and tourism industry, local governments should establish a breakthrough in the “intangible + tourism development model” in terms of institutional mechanisms, policies and standards, taking into account the specific situation of China, and provide a sustainable development direction for “intangible + tourism navigation and backup protection”. The first is to strengthen organizational leadership and improve the institutional mechanism of integrated development of culture and tourism. To establish a leading group for the development of “intangible heritage + tourism,” strengthen the style and effectiveness of government departments, to establish a sound communication and liaison mechanism, to improve the performance assessment and incentive mechanism, and to give full play to the guiding role of government departments in the development of “intangible heritage + tourism.” The second is to strengthen planning and design, and develop action plans and specific programs for the integration of cultural tourism. Adhering to the concept of advanced planning, standing in the height of an industrial layout, the development of “intangible cultural heritage + tourism” involves a number of departments and areas of overall planning and strategic deployment, the development of corresponding planning design and action plans to promote the implementation of related work. The third is to improve the policy system and establish the ICH + tourism development model. The government has introduced special policies for the integrated development of the cultural industry and the tourism industry in terms of finance, finance, talents and land, supported the development with comprehensive policies, reasonably planned the secondary distribution of funds by cultural and tourism bureaus in various cities, provided strong guarantee for promoting the development of “intangible cultural heritage + tourism,” and formulated the “intangible cultural heritage + tourism” demonstration project selection system. The “non-foreign heritage + tourism” demonstration project selection system is formulated, and policy tilts are given to high-quality projects and high-growth enterprises to create regional “non-foreign heritage + tourism” benchmark projects and play a demonstration and a leading role [19].


### 4.3.3. Expand the Industrial Chain of “Non-Foreign Heritage + Tourism” in an Orderly Manner, and Promote the Sustainable Development of Cultural Tourism Synergy

Based on the analysis of the empirical research results, the key indicators and contents are aligned, and the goal is to promote the effective synergistic development of the industrial economy of the two systems with the coupled and coordinated development of “non-heritage + tourism,” which requires the extension of the industrial chain of cultural and tourism integration. The complete industrial chain shows the coordinated and healthy development of the “NRM + tourism” industry. To further promote the innovation and synergy of culture and tourism, we need to build an industrial chain as the framework support. Based on the attributes of the multifaceted linkage of “NRM + tourism,” we can effectively drive the linkage of regional industries, expand the industrial chain of “NRM + tourism” in an orderly manner, give full play to the correlation of culture and tourism industries, and promote the sustainable development of “NRM + tourism.” It is an effective path to ensure the high-quality and coordinated development of China’s intangible cultural heritage and the tourism industry [25].In the analysis of China’s economic factors industry distribution, categories, upstream and downstream resources relationship, history and other basis, focus on judging the coordinated development of China’s economy, the status and role of the “invisible + tourism” industry, and the time, from the actual starting point and Wenxing travel, Wenxing travel, special cultural tourism, not only can extend the “invisible + travel” tourism industry chain, cultivate new tourism economic growth points but also allow more foreign tourists to understand China’ s history and culture, expand the influence, attractiveness, and competitiveness of culture. Linking the local economic zone “intangible + tourism” characteristics of resources, cultural tourism around the building area performing arts, catering tourism, leisure, night market subdivision to form a full industry chain, such as ecological experience, to enhance the “intangible + tourism” travel, product quality improvement, innovation “cultural tourism industry chain+,” cultivate “non-material learning tourism,” “non-material recreation tourism” and other new economic growth points. We continuously strengthen the chain extension and realize the complementary advantages and strong combination of “intangible cultural heritage + tourism” industry chain with China’s economic zone. We insist on relying on the dual advantages of natural ecology and humanities and history, complementing and strengthening the “intangible cultural heritage + tourism” industry chain, which is a scarce link between ecological experience and historical heritage in China’s economic zone with superior natural conditions and unique regional culture, and promoting the differentiated development of cultural tourism industry. We will take the initiative to coordinate all parties, coordinate consideration, planning and promotion, deeply integrate into the cultural tourism industry chain, and create a number of “intangible cultural heritage + tourism” industry clusters with distinct advantages, high-end cutting, and chain connection.

## 5. Conclusion

In this paper, we refer to relevant domestic and foreign literature, and sort out the current situation of domestic and foreign research and the development of domestic intangible cultural heritage, and explain that intangible cultural heritage resources can be transformed into cultural capital and thus gain economic value through cultural capital theory. The value of intangible cultural heritage is assessed and measured by IPA model analysis, Kernel density estimation (KDE), and gray correlation method (calculated by using the results of IPA analysis). Through the analysis of the distribution quantity and density of national intangible cultural heritage and the gray correlation between the intangible cultural heritage tourism industry and related industries, the following suggestions for the development of intangible cultural heritage are proposed as follows: (1) To deeply explore the connotation of “intangible heritage + tourism” and increase the development of cultural tourism resources. To promote the coordinated development of coupling, we should improve the image of culture and tourism through deep excavation of the connotation of “intangible cultural heritage + tourism” on the basis of the integration and joint development of “intangible cultural heritage + tourism” resources. In-depth excavation of regional intangible cultural heritage and tourism common source connotation, we explore the connotation and cultural lineage behind the “reference,” which is an important link between intangible cultural heritage and tourism industry resources link, effective synergy. Product development of “intangible cultural heritage + tourism” in China is an important means of differentiating cultural tourism products and a source of core competitiveness of cultural tourism products. (2) To give full play to the guidance of the government of “non-foreign heritage + tourism” and improve the long-term mechanism for the integration of culture and tourism. It is necessary to give full play to the role of the government, carry out overall planning, and improve the long-term mechanism for the effective integration of “intangible cultural heritage + tourism.” Government guidance and improvement of mechanism are the top-level guarantee for the coordinated development of intangible cultural heritage and the tourism industry. The synergy of “ICH + tourism” in China is a systematic work involving multiple departments and fields, which requires government departments to stand at the height of the strategic overall situation, carry out scientific planning with advanced concepts, build a long-term mechanism for the integration of culture and tourism, and promote the regional “ICH + tourism.” In-depth synergistic development, we should make full use of the guidance of local governments, form a coordinated and unified promotion mechanism of relevant departments, and build a development idea and long-term mechanism of “policy support, protection priority, market operation, and cultural tourism synergy.”
