## Abstract

In order to solve the problem of mismatch of supply and demand of TV programs in different regions, this article attempts to start with the influencing factors of the demand structure of programs and explore ways to improve or solve this problem of mismatch of supply and demand. The population needs to accurately correlate with the TV program, and educational structure is mainly taken into consideration. The objective of this study is to analyze the correlation between the population’s educational structure and the share of program rating using sampling of population. The method of multisample regression is used with the combination and derives the conclusion that the educational structure of the population has a significant impact on the share of program ratings. The proposed method introduces the population and the share of program ratings as explanatory variables and explained variables into the regression model to verify whether the educational structure of the population will affect the share of program ratings. Both the full-sample benchmark regression and robustness test results show that the educational structure of the population does affect the show’s viewing share. The impact is mainly manifested in the difference in the impact of the proportion of the population of different educational backgrounds on the audience share of the same type of program. In order to increase the effective supply of programs, each region should arrange programs according to local conditions, and the presentation of programs should reflect stepped characteristics.

## Body

## 1. Introduction

As an intermediary that connects people to society and the relationship between people, it is inevitable that the media industry will play an important role in the economic and social fields. Relevant studies have shown that factors such as economy, region, population, and technology have an important influence on the development of the media industry [1–3]. As an important part of the media industry, TV programs play an important role in economy, society, and culture [4–6]. Generally speaking, the viewership share of different types of TV programs in a region not only reflects the degree of preference for the programs by the audience groups in the region, but also reflects the demand structure of various TV programs. The broadcast share of TV programs in a region reflects the supply structure of various TV programs in the region [7, 8].The difference between the TV program’s viewing share and the broadcast share represents the matching of the TV program’s supply and demand. If there is a difference between the two, it means that there is a mismatch between supply and demand for TV programs, and the greater the difference, the more serious the mismatch [9, 10]. At present, the most influential ratings survey company in the world is AGB Nielsen. Others include Arbitron Company in the United States, BARB (Broadcaster Audience Research Board Limited) in the United Kingdom, TNS, Video Research Ltd. in France, and BBM in Canada [11–14]. Regarding China’s domestic audience rating survey market, CCTV-Sofuri and AGB Nielsen accounted for almost all of the market, with about 80% and 10–15%, respectively. At the same time, many scholars have carried out research in the field of program recommendation [15]. Yan et al. proposed an adaptive time model, which mainly uses program metadata for division [16]. Jie et al. provided an IPTV-based plug-in system to assist in recommendations [17]. Paolo et al. researched and improved the cold start problem of the IPTV system [18]. Jongwoo et al. realized user recommendation by clustering IPTV programs [19].The structural characteristics of the audience group’s demand for TV programs depend on the structural characteristics of the audience group itself, which in turn determines their viewing or selection behavior of TV programs [20, 21]. Two factors, social structure and media structure, will affect the media selection behavior of the audience. The audience’s education and related income levels, work conditions, personal tastes, leisure time, and so forth are all specific factors that affect their choice of a certain medium. Relevant empirical research shows that population quality factors related to education do have a significant impact on the development of the media industry. Not only that, but demographic structural factors also play a significant role in industrial development. In view of this, this article will then study its impact on TV program ratings from the perspective of population educational structure, so as to provide relevant enlightenment for improving or solving the problem of TV program supply and demand mismatch.


## 2. Related Work

Based on the population, the classification of the study is made.


### 2.1. Overview of Viewership Share

With the continuous expansion of the TV media, the TV media are paying more and more attention to the statistical data of viewership ratings, such as determining the advertising prices of various channels and time periods and evaluating their own program types. The statistics of viewership share has become an important basis for them and advertisers to choose media, channels, program types, and time periods [22–24]. Current TV media ratings surveys are still very imperfect. First, relatively single ratings survey data cannot quantitatively analyze the factors that affect the program ratings. The second is the ratings survey system for postbroadcast surveys and analysis and evaluation of programs, and prebroadcast predictions are not possible for ratings [25, 26]. When Nielsen data is imported, basic data can be obtained. The data statistical analysis module can restatistically analyze data such as program type, channel, time period, and program analysis and provide graphical display statistics of previous data. Figure 1 shows the analysis and statistics module diagram of the existing ratings.Figure 1
Diagram of the existing audience rating analysis and statistics module.According to different viewpoints and perspectives, to extract the evaluation of data from different directions, we need to use data mining algorithms to perform cluster analysis on the data that affects the ratings and obtain the relationship factors that affect the ratings [27, 28]. In addition, a quantitative evaluation index system and accurate performance evaluation standards are formed, and reasonable statistics are made on various factors such as program time period benefits, channel evaluation, program type, channel coverage, actors, and directors, and quantitative analysis is performed within a specified time period. The evaluation indicators are visually displayed in user-defined charts, such as zoom able 3D column chart, pie chart, and line chart.

## 3. Methodology

The methodology is based on the correlation of the share measurement model where regression model is used as empirical purpose.


### 3.1. Share Measurement Model Design

The difference in education background will affect the individual’s professional level, employment nature, time distribution, income level, and hobby type to a certain extent, thereby affecting their preference for different types of programs [29, 30]. In order to study whether the educational structure affects the viewership share of TV programs and how it affects it, this article will then combine the panel data of 29 provinces (cities, districts) in China from 2009 to 2019 and use a panel regression model to empirically test the educational structure of the population in different regions. For the impact on the share of TV program ratings, the empirical research of this article is divided into three parts: (1) full-sample benchmark regression to verify whether the educational structure of the population affects the TV program audience share; (2) based on the classification regression of samples from eastern, central, and western provinces, to test the regional difference of the population’s educational structure to the share of TV program ratings; (3) sample classification regression based on the educational structure of the population and program types to test the influence of the proportion of the population with different educational backgrounds in each region on the audience share of different types of programs.In the part of the full-sample benchmark regression, this paper establishes the following panel regression model for empirical purposes:(1)ratingsi,t=β0+β1edui,t+νi,t,(2)ratingsi,t=β0+β1edui,t+γcontroli,t+νi,t,(3)ratingsi,t=β0+β1edui,t+γcontroli,t+ηi+νi,t,(4)ratingsi,t=β0+β1edui,t+γcontroli,t+ηi+μt+νi,t.Here,ratingsi,t, edui,t, and controli,t represent the share of TV program ratings, the educational structure of the population, and other control variables in the t period in the i area. ηi and μt represent the individual fixed effect and the time fixed effect. νi,t is the random error term. From the perspective of the types of model (1) to model (4), model (1) is a panel OLS estimation regression model without control variables; model (2) introduces control variables on this basis; model (3) controls individual fixed effects on the basis of model (2). Equation (4) further controls the time fixation effect.In terms of the selection of the explained variable, since the “China TV Rating Yearbook” published the ratings share data of 15 types of TV programs in 29 provinces (cities, districts) from 2009 to 2019, this article directly introduces this indicator as an explained variable into the regression model [31, 32]. Considering that there is a very strong correlation between the broadcast share of TV programs and the audience share, this paper takes the broadcast share of TV programs as the explained variable to conduct a robustness test. Judging from the 2009–2019 data on the ratings and broadcast shares of various types of TV programs in 29 provinces (cities, districts) published in the “China TV Rating Yearbook,” the absolute value of the difference between the broadcast shares (hereinafter referred to as the absolute difference) showed undulating characteristics during the study period and did not show a steady downward trend. In other words, there is a mismatch between supply and demand for various TV programs in major provinces (cities, districts) in my country, and this problem has not been effectively improved. Figure 2 depicts the average absolute difference between the viewership share and the broadcast share of various TV programs in 29 provinces (cities, districts).Figure 2
The average absolute difference between the viewing share and the broadcast share of various TV programs in 29 provinces (cities, districts).In terms of the selection of explanatory variables, the National Bureau of Statistics has released sample data of the population of 31 provinces (cities, districts) who have not attended school, elementary school, junior high school, high school, junior college, or above. This article uses these sample populations with different educational backgrounds. The proportion of the number in the total sampled population reflects the educational structure of the population in each region. Regarding the selection of control variables, considering that economic, cultural, technological, and other factors will affect the TV program ratings, this article selects the number of public libraries to reflect the cultural public service level of each region and selects the number of cultural relics to reflect each region. Regarding the historical background of the industry, the number of Internet access ports is selected to reflect the level of technological development in different regions, the per capita GDP is selected to reflect the economic development level of each region, and the proportion of the added value of the tertiary industry is selected to control the macroenvironmental factors that affect the development of the tertiary industry. The original data of all control variables come from the “Regional Economic Yearbook” over the years. The final empirical sample of this article is the 2009–2019 data of 29 provinces, autonomous regions, and municipalities other than Qinghai and Tibet. Among them, 15 types of TV programs include TV series, movies, variety shows, news and current affairs, and finance. For a small number of missing values in the original data of the empirical sample, this paper uses the moving average interpolation method to fill in. In order to facilitate the comparison of the regression coefficients of different grouped samples, this paper will perform logarithmic processing on all variables when performing regression. The statistical description of all variables is shown in Table1.Table 1

Regarding the junior high school education, the proportion of the population is the largest in the central region, followed by the eastern region, and the smallest in the western region; the proportion of the population with a high school education shows a pattern of decreasing in the east, middle, and west. Regarding the proportion of the population with a college degree and above, the provinces in the eastern region have an absolute leading advantage, and the provinces in the central and western regions are relatively close. Figure3 shows the distribution of the educational structure of the population in different cities.Figure 3

## 4. Empirical Analysis

### 4.1. Full-Sample Benchmark Regression

This article first takes the proportion of the population who has not gone to school as an explanatory variable and introduces the TV program audience share as an explained variable into the regression model to test whether the population’s educational structure affects the TV program audience share. The results of the full-sample benchmark regression are shown in Table2.Table 2

Regarding the audience share of the type of TV show, from the regression results of the full-sample data, the TV program audience share is more sensitive to changes in the proportion of the population who has not gone to school. For every 1% increase in the proportion of the population who has not gone to school, the TV program audience share will increase accordingly: 0.742%–1.244%. Next, this article will use the proportion of the population without going to school as an explanatory variable, and the share of TV shows as an explained variable into the regression model to conduct a robustness test. The results of the robustness test regression are shown in Table 3.Table 3

### 4.2. Grouped Sample Regression

There are certain differences in economic development, social customs, and distribution of educational resources in the eastern, central, and western regions. This may lead to differences in the impact of the educational structure of the population on the TV program ratings. Therefore, based on the full-sample regression data, this paper regressed the samples from the eastern, central, and western regions, respectively. The regression results of grouped samples in the eastern, central, and western regions are shown in Table4.Table 4

This also further verified the robustness of the basic regression results. Among them, from the perspective of the size of the regression coefficient, the regression coefficient in the western region is the largest, followed by the central region, and the regression coefficient in the eastern region is the smallest. This shows that the educational structure of the population in the eastern, central, and western regions does have significant differences in its influence on the TV program audience share. Since the proportion of the population without going to school shows a sequential increase in the eastern, central, and western regions, the regression results in Table 5 further show that the larger the proportion of the population without going to school, the greater the share of TV program ratings, and the greater the impact.Table 5

Next, this article further explores how the educational structure of the population affects the viewing shares of different types of programs, so as to provide relevant enlightenment for each region to rationally arrange the share of TV programs and improve the efficiency of TV program supply according to the educational structure of the population. In order to facilitate the return of groups and eliminate the effects of other factors as much as possible, this article deletes programs that have a small viewing share and are specific to the target audience’s age, gender, and educational background, including teaching, foreign languages, youth, music, and drama. There are six kinds of sports programs. After calculation, the remaining TV programs after the deletion account for about 85%–96% of the audience, which is very representative. According to program attributes, this article divides these remaining TV programs into four categories: (1) movies, TV, and variety shows; (2) news, current affairs, and topics; (3) finance and legal system; (4) life services and others. On this basis, we will separately study the specific impact of the proportions of the population without schooling, elementary school, junior high school, high school, and junior college and the proportions of these five types of education on these four types of programs. Due to space limitations, only the regression coefficients and important statistics are reported below in this article. The sample regression results divided by program type and population educational structure are shown in Table 5.It can be seen from Table5 that the ratings of movies, TV series, and variety shows are not sensitive to changes in population educational structure, and the regression coefficients are not significant. Movies, TV series, and variety shows are rich and diverse, which can meet the various needs of different groups of people. And because the same program can be broadcast in different regions, different time periods, and multiple channels at the same time, the viewing time of the audience group is more flexible. To a certain extent, it explains why the educational structure of the population has no significant influence on the audience share of this type of TV program. Financial and legal programs are very sensitive to changes in the educational structure of the population. Among them, the proportion of the population with no schooling, elementary school, middle school, and high school education has a significant positive impact on its viewing share, and the proportion of the population with a college degree and above has a significant negative impact on its viewing share. The possible reason is that people with relatively low academic qualifications can broaden their horizons and inspire their thinking by watching financial and legal programs with common sense or popular science. Therefore, these people will have a certain degree of preference for such TV programs. For people with a college degree or above, because they have a relatively rich knowledge reserve, the common sense or popular science knowledge provided by financial and legal programs relatively lacks professionalism. They are more inclined to obtain the required knowledge or information through other channels than TV programs, so they show obvious nonpreference for such TV programs. In addition, the limitation of working hours may also be the reason why people with a college degree or above are less watching financial and legal programs.The obvious nonpreference of the population with junior high school education and below towards news, current affairs, and special programs needs to be taken seriously. The population with a high school degree and below shows a clear preference for finance and legal system as well as life and service programs, while the population with a college degree and above shows nonpreference for finance and legal system. Life and service programs also need to be paid attention to.


### 4.3. Recapitulation

From Figure4, we can compare the performance of the algorithm with benchmark study [33]. The study has also applied regression for better estimation based on their variable, and the results of the proposed study are better than the state of art if we consider the value of P.Figure 4

## 4.1. Full-Sample Benchmark Regression

This article first takes the proportion of the population who has not gone to school as an explanatory variable and introduces the TV program audience share as an explained variable into the regression model to test whether the population’s educational structure affects the TV program audience share. The results of the full-sample benchmark regression are shown in Table2.Table 2

Regarding the audience share of the type of TV show, from the regression results of the full-sample data, the TV program audience share is more sensitive to changes in the proportion of the population who has not gone to school. For every 1% increase in the proportion of the population who has not gone to school, the TV program audience share will increase accordingly: 0.742%–1.244%. Next, this article will use the proportion of the population without going to school as an explanatory variable, and the share of TV shows as an explained variable into the regression model to conduct a robustness test. The results of the robustness test regression are shown in Table 3.Table 3

## 4.2. Grouped Sample Regression

There are certain differences in economic development, social customs, and distribution of educational resources in the eastern, central, and western regions. This may lead to differences in the impact of the educational structure of the population on the TV program ratings. Therefore, based on the full-sample regression data, this paper regressed the samples from the eastern, central, and western regions, respectively. The regression results of grouped samples in the eastern, central, and western regions are shown in Table4.Table 4

This also further verified the robustness of the basic regression results. Among them, from the perspective of the size of the regression coefficient, the regression coefficient in the western region is the largest, followed by the central region, and the regression coefficient in the eastern region is the smallest. This shows that the educational structure of the population in the eastern, central, and western regions does have significant differences in its influence on the TV program audience share. Since the proportion of the population without going to school shows a sequential increase in the eastern, central, and western regions, the regression results in Table 5 further show that the larger the proportion of the population without going to school, the greater the share of TV program ratings, and the greater the impact.Table 5

## 4.3. Recapitulation

Regression results of samples.


## 5. Conclusion and Inspiration

The data on TV program ratings and broadcast shares show that there is a mismatch between supply and demand for TV programs. In view of this, this article starts with the educational structure of the population, combines the panel data of 29 provinces (cities, districts) from 2009 to 2019, and uses a panel regression model to study its impact on the TV program ratings share. The regression results show that, for the eastern, central, and western regions, the proportion of the population who has not gone to school has a significant positive impact on the TV program audience share, but from the regression coefficient, the western region is the largest, and the central region is the second. The east is the smallest. Further combining the characteristics of the average educational background of the population in these three regions, it can be seen that the larger the proportion of the population who has not gone to school, the greater the impact of its changes on the TV program audience share. In addition, the sensitivity of various TV programs to changes in the proportion of the population with different educational backgrounds is also different. They are the least sensitive to changes in the proportion of the population who has not gone to school. Based on the above research, this article believes that each region should reasonably arrange TV programs in accordance with the educational structure of the population in the region and local conditions. From the perspective of program types, the focus should be on finance and legal system, life services, and other types of programs. TV programs of the same type should have a stepped feature in content arrangement, so as to meet the needs of people with different educational backgrounds as much as possible. Future work can check the result using deep learning neural network model.
