## Abstract

Accounting work is more efficient when it is computerized, and the rate of errors is lower. The incentive mechanism should be improved before the development of management accounting practice in businesses. The emotion of employees in enterprises is a determinant of the spread of management accounting practice in businesses. Employees’ resistance to management accounting practice can be effectively addressed through incentive mechanisms. As a result, in order to encourage the growth of management accounting in businesses, they must first create a perfect management accounting incentive mechanism. The implementation of a management accounting information system is made more difficult by these new categories. The construction of a management accounting information system based on BI and mobile edge computing is systematically discussed in this study. BI has the advantage of being able to model in a variety of ways, process large amounts of data efficiently, and provide managers with actionable data quickly. To realize the quantitative analysis of cost, income, and input-output, the system employs advanced technologies such as data warehouse modeling, data acquisition, data display, and security design. Management accounting has emerged as the best choice for the innovation of enterprise management mode as an accounting service for the internal management of businesses. Big data in management accounting serves as a company’s “asset,” providing a wealth of information. It has become critical to understand how to mine and use big data information to provide a foundation for management accounting. This study explains how to collect data, prepare data, establish a model, mine data, and analyze data using a big data and mobile edge computing algorithm and identifies the key indicators affecting enterprise management accounting risk analysis through empirical analysis. The study of the diffusion mechanism and influencing factors of management accounting practice within enterprises and between enterprise clusters can help promote the development of management accounting practice and speed up the construction of China’s localized management accounting system.

## Body

## 1. Introduction

With the development of science and technology, the degree of informationization is getting higher and higher in the practice of financial management. Many enterprises pay attention to relying on information technology to optimize the financial management level of enterprises as a whole and have also embarked on the road of computerization [1]. Accounting computerization can be divided into financial accounting computerization and management accounting computerization [2]. The work content of computerized financial accounting is reimbursement to enterprises, with the focus on financial statistics, which belongs to the category of external accounting. Computerized management accounting focuses on business management, past evaluation, present decision-making, and future development, which belongs to the category of internal accounting [3]. The data source cannot be unknown during the systematic analysis and design of management accounting software. With an increasing number of businesses adopting computerized accounting, it is more important than ever to figure out how to make the most of accounting software’s ready-made accounting data [4]. Management accounting should be viewed as a design science rather than a simple explanation. As a result, management accounting research should move beyond the “problem, hypothesis, test, and correction hypothesis” explanatory scientific research paradigm. Scientific research methods such as case studies, experimental research, and analytical model research should be strengthened in management accounting. The majority of China’s localized management accounting tools and ideas come from the West, but China’s market system, economic environment, and social culture are vastly different. Therefore, some management accounting practices will not be suitable for the development of Chinese enterprises. The research of this study is helpful for enterprises to deeply understand and learn management accounting practice and then choose management accounting tools suitable for enterprises themselves. Secondly, the research of this study provides a reference for the financial department to formulate policies to promote the development of management accounting and for the construction of management accounting system [5].What the company needs most for internal control is accounting information. Accounting information provides an information source for the company’s decision-making [6]. According to this demand, this study implements an enterprise management accounting information system aimed at analyzing the past, controlling the present, and planning the future [7]. The system introduces data warehouse technology, through the cleaning and integration of multiparty data such as business system, financial accounting, credit management, and asset management and statistics, and based on the input-output of financial products, the system makes a quantitative analysis of costs, benefits, and input-output of institutions, departments, outlets, customer managers, and employees [8]. How to make the big data method play a greater role in the application of management accounting is the direction we should strive for. Big data are not only a powerful analysis tool but also an important asset and wealth of enterprises. Enterprises should pay more and more attention to big data [9]. Computerized accounting can not only realize the automatic processing of electronic data information but also develop into computerized accounting management mode through the traditional manual accounting financial management mode [10]. Although financial accounting computerization is the main tool and means at present, management accounting computerization is the trend of development in the future [11].With the development of my country’s economy and the integration of the world economy, the management methods of traditional financial accounting after the event and regular supervision have been difficult to meet the needs of modern enterprise management and management, strengthen the internal management and control of enterprises, and actively respond to the international competition of enterprises. It is the general trend [12]. To integrate into a perfect system, a cost management system must go through four stages of continuous evolution. At the same time, technology research and development are influenced not only by the technology and the organization but also by a complex interaction effect influenced by the internal and external environment. Traditional accounting and financial management are not the same as accounting computerization. This work has the potential to not only improve the efficiency of corporate accounting work but also to standardize the internal management system and ensure the smooth progress of accounting computerization, which is critical for enterprise modernization [13]. The big data method can effectively process massive structured and unstructured data information, find the trends and logical laws hidden behind the data, and provide management for decision-making as a means of mining the value behind the data. In the operation management process, valuable information aids enterprises in strategic management, budget management, investment and financing management, operation management, performance management, and cost management [14].The novelty of this study is as follows:(1)
This study expounds on how to use big data and mobile edge computing algorithms to collect data, prepare data, build models, mine data, analyze data, and determine key indicators that affect enterprise management accounting risk analysis through empirical analysis.(2)
The diffusion mechanism and influencing factors of management accounting practice within enterprises and among enterprise clusters are studied, which will help to promote the development of management accounting practice and accelerate the construction of China’s localized management accounting system.


## 2. Related Work

Literature [15] first proposed a property-based association rule mining algorithm. Literature [16] further puts forward four main technologies to support data mining on the basis of research. Literature [17] combined with the historical process of China’s economic development and the development space of China’s management accounting, based on the social function of management accounting discipline; it is proposed that China’s management accounting is facing the best strategic opportunity period. According to the basic situation of China’s national conditions, the application system and theoretical framework of management accounting based on the background of China’s enterprise system are put forward [18]. Literature [19] proposed to study the relationship between enterprise demand and information systems based on contingency theory. Literature [20] proposed to study the relationship of participants with corresponding relationships in system implementation based on social capital theory and actor-network theory, paying special attention to stakeholders and businesses in a wider range.Literature [21] discusses the social value and strategic choice of human society entering the digital information age and big data being widely used in various fields. Literature [22] proposed the classification framework of sampling methods in the process of data mining and compared and analyzed the advantages and disadvantages of data mining sampling methods in different scenarios. Literature [23] pointed out that even in developed countries, some functions of enterprise ERP information system are not fully integrated with other software, and the functions of some systems have not been brought into full play. Literature [24] pointed out that the lack of effective theoretical guidance is the fundamental reason why the application of management accounting methods in Chinese enterprises is relatively backward. Literature [25] analyzes many important problems existing in the transformation period of management accounting in China and gives corresponding strategic suggestions. Literature [26] proposes a new data algorithm for effective mining and analysis of semistructured data, which overcomes the problem that the traditional data mining technology can not effectively mine semistructured data.


## 3. Methodology

### 3.1. Access Operation of Computerized Management Accounting

Accounting computerization refers to the management mode commonly used by Chinese enterprises in various stages, using computer technology to complete accounting. Computerized accounting can not only realize the automatic processing of electronic data but also convert the traditional accounting calculation mode to the electronic calculation mode, reducing errors caused by manpower calculations. The accounting data warehouse storage subsystem is the key to the accounting analysis management system. It mainly operates the ETL process for the data in the enterprise system of the accounting data extraction subsystem, stores the data in the unified DW according to the standard format, and realizes the effective sharing of data among enterprises. The relationship between financial accounting and management accounting is clarified, and the connection between financial accounting and management accounting data file settings under computerization is understood, so that we can make full use of the current financial accounting data in accounting software. Data, as a starting point for predicting the future of an enterprise, have important practical significance to effectively serve the internal management of the enterprise. The accounting access system is shown in Figure1.Figure 1
Accounting retrieval system.Cloud service providers should also include modules for rapid cloud computing software development and provide flexible customized functions and online customized services to meet the personalized needs of small and medium-sized businesses, so that small and medium-sized businesses can adjust the matching accounting information software functions and services at any time based on their own business characteristics and demand changes. Many data can be directly retrieved from the accounting system using management accounting software. The practice of management accounting is a crucial part of the enterprise management process. It primarily provides relevant information for enterprise management planning and management control, as well as creates and increases value for shareholders, customers, and other stakeholders by continuously checking and judging whether organizational resources are being used effectively. The academic attention analysis of management accounting practice development is shown in Figure2.Figure 2
Analysis of academic attention to the development of management accounting practice.The diffusion of management accounting practice in enterprise clusters needs to go through four stages: cognition, analysis, decision-making, and integration. The internal and external environments of enterprises, the characteristics of management accounting practice, and enterprise resources are the main factors affecting the changes of model parameters. Direct data access is convenient, but in the generation of management reports, more data are obtained after decomposing the accounting certificate, account, and table data. Its biggest advantage is that it is convenient to provide information on the profitability of each product, so as to provide an important basis for the management department to formulate profit plan and operation management. By adjusting the parameter values, we can further analyze the practice diffusion process in different situations. The equilibrium points obtained by different parameter values are different, and the diffusion time required for management accounting practice is also different. The specific simulation results are shown in Figures3 and 4.Figure 3
α ∼ 0.03 and γ ∼ 0.01.Figure 4
α ∼ 0.08 and γ ∼ 0.05.There are many sources of data: first, the main business data of assets, liabilities, intermediate business and operating expenses are obtained through docking with the urban comprehensive network and general ledger system, and the internal transfer price is used to determine the operating costs and operating income of suboutlets, subsectors, and products. Second, the change data of various business indicators of customer managers and outlets are obtained through docking with the business subaccount data of urban integrated network, and the business performance of outlets and customer managers is determined through internal transfer price calculation. Third, the operating expense cost of each responsibility center is determined, and the corresponding amount of the depreciation of fixed assets occupied and allocated to departments, products, outlets, and customer managers is obtained. The application of management accounting in enterprises is also the transformation of old and new management accounting systems and methods and systems, which is manifested in the selection, adoption, and absorption of new management accounting tools. Data source is the foundation of data warehouse and the data source of the whole system, including internal information and external information. Big data analysis method is a process of using some algorithm and mathematical model to analyze the massive data information mined on the platform of computer system and then find useful information from these data information or find the laws and trends behind some data. Data mining technology constructs relevant models through classification, deviation analysis, association analysis, and decision-making, analyzes the correlation between attribute values by using statistics, machine learning, and other technologies, and transforms the data into the knowledge required for decision-making.


### 3.2. BI Technology

At present, BI has been applied to every link of the company’s management. Only from the overall perspective and paying attention to the quality of management accounting, enterprises can provide a clear route for their future development. The process of big data analysis needs the intersection of computer algorithms, statistics, artificial intelligence knowledge, database management, information processing system, and decision theory. The comparison of total cost of ownership between traditional construction and cloud computing is shown in Figure5.Figure 5
Comparison of total cost of ownership between traditional construction and cloud computing.Big data analysis can help enterprises to use data for analysis, find valuable information from data, and help enterprises to make strategic plans or give early warning of certain risks in the future. System information is to assist leaders in making decisions, and its accuracy is extremely important. On the other hand, the systematic data involve all aspects of banks, and some data are sensitive. Therefore, the system adopts a perfect security encryption mechanism; and at the same time, in order to avoid the loss of business data, it provides backup and recovery strategies, which makes the whole system have good security management performance. In management accounting, data support should be provided for major decisions of enterprises, so that managers can make scientific decisions based on data. BI process is based on a large amount of data, which is orderly stored in DW after being processed by ETL technology. This method can not only provide ideas for management accounting work but also improve the efficiency of accounting work, so that enterprise management accountants have a deep understanding of the work direction. Computerized accounting is not a separate information system, and a complete computerized accounting system contains many subsystems. Therefore, the running efficiency and system structure of each subsystem are analyzed. Once a subsystem has problems, it will have an impact on the whole computerized accounting system. BI process is shown in Figure6.Figure 6
BI process.The first step in improving management accounting practice in businesses is to improve the incentive mechanism. The emotion of employees in businesses is a determinant of the diffusion of management accounting practice in businesses. Employees’ resistance to management accounting practices can be effectively addressed through incentive mechanisms. As a result, in order to promote the growth of management accounting in businesses, they must first create a perfect management accounting incentive mechanism. Transitioning from financial accounting to management accounting computerization can improve enterprise financial management efficiency and allow businesses to improve their financial management system. Major decisions are frequently made by businesses in the course of their operations, and good decisions will help businesses grow. Figure7 shows a change chart of labor productivity and operating cycle based on BI technology.Figure 7
Variation chart of labor productivity and operating cycle.Multidimensional business indicator analysis is realized, and detailed indicator data are provided for multidimensional business analysis according to the data collection method based on account and account. For different responsibility centers, different drivers are used to decompose the cost into transactions or products, that is, the cost of network responsibility centers is decomposed by transaction volume, and the cost of operation, service, and management responsibility centers is decomposed by gross income, average value of assets and liabilities, transaction volume, and other drivers of each product within the scope of management or service, so as to calculate the cost of products. Due to the multisource nature of the basic data, the system uses the data extraction scheme to complete the data conversion from the basic data to the fact table. Data extraction, through the solution of the organization form of data files in the source database, extracts the basic data effective for the whole system from the source database, performs aggregation operation on the basis of these data, calculates new data items, and saves them in the fact table of the data warehouse. Through BI technology, the company can effectively integrate and analyze the existing data of the company on the basis of the original budget system. Using BI technology, the company’s financial personnel can get accurate data analysis results in time and solve the contradiction between data timeliness and accuracy in traditional accounting. The system is closely combined with the database, which is convenient to maintain the data integrity of the database system. The background database provides a highly perfect security mechanism, restricts the access mode of the data database, and strictly restricts the direct operation of the client to the database. The databases with other systems are not open to each other, and data exchange is carried out through data interface or data file. According to the attitude towards management accounting practice, the subjects of management accounting practice diffusion are divided into neutrals (T), opponent R (T), and supporter I (T). Therefore, the proportion of the final three groups is as follows:(1)dstdt=−λrtst−γst+δrt+αit,(2)drtdt=λrtst−δrt−μrt,(3)ditdt=μrt+γst−αit.The diffusion process shall meet the following conditions:(4)λα−α+γα+μλα+μ<λμ+γ−μδ+μλα+μ.So, simplification is continued as follows:(5)λα−μ<γ−μδ+μ+α+γα+μ.(1)
At the timeα>μ, meet λ:(6)0≤λ<γ−μδ+μ+α+γα+μα−μ=k1.(2)
At the timeα<μ, meet λ:(7)k2=γ−μδ+μ+α+γα+μα−μ<λ<δ+μ.

## 4. Result Analysis and Discussion

### 4.1. Big Data Method for Management Accounting

When analyzing big data methods, we should apply different tools, technologies, and algorithms or combine them according to the different sources, forms, and structures of big data, so as to fully tap the hidden value behind the data. This part mainly studies the data of project analysis process, which has different forms, including structured data and unstructured data. There are also different types of data, such as text, images, tables, videos, location information, and so on. For example, when analyzing the financial risks of enterprises, it is necessary to collect data indicators such as operating ability indicators, profitability indicators, growth ability indicators, and solvency indicators. At present, most enterprises in China have realized computerized accounting management and completed financial accounting and data collection through computers, saving manpower and material resources, and improving accounting accuracy and working efficiency. Under the guidance of advanced technology, accounting computerization is transforming and developing. Intelligent programs replace manual bookkeeping, data sorting, entry, etc. The working pressure of accountants is constantly decreasing, and they can have more time to solve other problems. Generally, the data required for preparing management statements can be divided into three categories. One is the voucher data from the voucher library file, including not only the filled-in accounting vouchers but also the data of original vouchers such as unit price and quantity of purchase and sales. This kind of data provides original data for analysis and calculation; The second type of data comes from account book documents, including the amount and balance of general ledger and subsidiary ledger summarized by department month at all levels, as well as the itemized and chronological records of each subsidiary ledger. This kind of data provides summary data for analysis and calculation. The third type of data is not from the accounting software but from other relevant data input through the keyboard. The overall data structure of management accounting is shown in Figure8.Figure 8
Overall data structure of management accounting.Using the big data method, management accounting can analyze all kinds of business data, which can provide decision-making basis for enterprise managers. By analyzing the income situation, we can find the reasons for the increase or decrease in income. The analysis of operating costs can help enterprises optimize management and reduce costs. Through the analysis of business risks, we can optimize the financial structure of enterprises and reduce unnecessary losses. There is a contradiction between the timeliness of data and the reliability of conclusions. For traditional accounting, it is difficult to give consideration to both, and it is inevitable to give consideration to one and lose the other. The data presentation part is based on the customer manager’s analysis of volume, cost, and profit and takes profit and cost as the clue to calculate the revenue, cost, and profit of departments, institutions, and products in detail, so as to determine the profitability of departments, institutions, and products, so as to reduce operating costs, improve the profitability of the bank, and provide scientific and reasonable decision-making basis for managers. The impact trend of threshold on the diffusion of management accounting practice is shown in Figure9.Figure 9
Influence trend of threshold on the diffusion of management accounting practice.The unified central database management can realize the comprehensive management of the interactive information, which can ensure the consistency of data processing technology and the synchronization of data update. Clustering and classification in the big data method can effectively extract the data, eliminate the combination with high correlation coefficient in the data, and select the main component factors for project analysis. Many unstructured or semistructured data can not be used directly. Data transformation can convert unstructured data into structured data for easy input into the system. Another main function of data conversion is to reduce the dimension of data, that is, eliminate some variables that describe the data features vaguely and retain the variables that are useful to the data features, so as to improve the efficiency of processing and analyzing data.


### 4.2. Practical Function of Accounting Computerization Application

Accounting computerization has now become the dominant form, owing to the comprehensive and rapid development of information technology. Accounting computerization has a significant practical significance in the practice of enterprise financial management as follows: (1) The information is provided to management. Big data not only give us a lot of text information, but they also give us a lot of unstructured data like videos, images, tables, and so on. Some data information is not directly readable. At this time, it is necessary to use big data processing methods for deep processing and to extract useful information from the data information for the future development of enterprises. The trend chart of enterprise case clustering analysis is shown in Figure10.Figure 10
Trend chart of enterprise case clustering analysis.Enterprises frequently need to effectively construct a perfect computerized accounting system in combination with their own development characteristics and financial management practice during the implementation process of computerized accounting in order to better reflect its role and functions. (2) The financial management quality of businesses is improved, and their financial practices are consolidated. Cash flow management is intertwined with the production management of a business. When a company requires funding, the current financing cost, financing risk, and financing scale must all be considered. (3) Performance evaluations are put in place.The application of computerized accounting can also promote enterprise financial managers to move forward from single professional quality to comprehensive quality. Financial managers should not only be familiar with the work of financial management but also have certain computer literacy. Enterprises in different industries choose different performance management tools and methods. Enterprises should choose the most suitable performance management method for their own development in combination with their own strategic planning, management needs, and business characteristics, so as to achieve the best employee incentive effect. To improve the effectiveness of internal accounting control, enterprises should take specific measures against these influencing factors. Management accounting actively embracing big data is an important step in the development of management accounting. Using Internet science and technology, we strive to mine more effective big data algorithms, so as to make management accounting play a greater role in business decision-making, investment decision-making, and financing decision-making and enable Chinese enterprises to grow and develop rapidly and healthily in the new environment. Firstly, the enterprise accounting management structure is improved and the attention of enterprise managers is strengthened to the internal accounting management. Secondly, the enterprise management system is improved to provide a reliable guarantee for the effective implementation of accounting internal control. Thirdly, the comprehensive quality of accountants is improved to adapt to the development of enterprises. Finally, the enterprise financial management is strengthened to improve the quality of financial information.

Influence trend of threshold on the diffusion of management accounting practice.The unified central database management can realize the comprehensive management of the interactive information, which can ensure the consistency of data processing technology and the synchronization of data update. Clustering and classification in the big data method can effectively extract the data, eliminate the combination with high correlation coefficient in the data, and select the main component factors for project analysis. Many unstructured or semistructured data can not be used directly. Data transformation can convert unstructured data into structured data for easy input into the system. Another main function of data conversion is to reduce the dimension of data, that is, eliminate some variables that describe the data features vaguely and retain the variables that are useful to the data features, so as to improve the efficiency of processing and analyzing data.


## 4.2. Practical Function of Accounting Computerization Application

Accounting computerization has now become the dominant form, owing to the comprehensive and rapid development of information technology. Accounting computerization has a significant practical significance in the practice of enterprise financial management as follows: (1) The information is provided to management. Big data not only give us a lot of text information, but they also give us a lot of unstructured data like videos, images, tables, and so on. Some data information is not directly readable. At this time, it is necessary to use big data processing methods for deep processing and to extract useful information from the data information for the future development of enterprises. The trend chart of enterprise case clustering analysis is shown in Figure10.Figure 10
