Research on Quality Evaluation and Promotion Strategy of Digital Economy Development

The digital economy is the trend of global economic development in the future. The development of the digital economy not only highly reflects the five development concepts of China, but also deepens the supply-side structural reforms and promotes the implementation of innovation-driven development strategies, thereby improving China's Competitive new advantages. After understanding the current status of domestic digital economy research, this article combines the connotation and characteristics of the digital economy, selects basic indicators from three dimensions of technology, economy, and environment, constructs an evaluation index system, and studies the quality of China’s digital economy development from 2009 to 2018. The shortcomings of China’s current digital economy development are analyzed, and effective promotion strategies are provided, in order to promote high-quality growth of the digital economy.


Introduction
The term "digital economy" was first proposed by Tapscott Don of the United States in 1996. In the following two decades, the network infrastructure construction has been continuously upgraded, the level of information processing technologies such as big data and the Internet has gradually improved, and the global digital economy has been developed. The trend is fast. In recent years, economic form of the digital economy has penetrated into all walks of life and fundamentally changed the development environment and activity forms of economic society. The digital economy is the trend of future economic development. It is a strong driving force to deepen supply-side structural reforms and reduce the gap between China and developed countries. However, the development of China's digital economy is in its infancy. How to promote the rapid development of China's digital economy Good development is a key issue that needs to be resolved in the construction of a "digital China" in the new era.

Highly Reflect the Five Development Concepts
China has proposed the five development concepts of "innovation, coordination, greenness, openness, and sharing". The development of the digital economy highly reflects our development philosophy. The digital economy is a new type of economic form, a product of the development requirements of the current era, and fully reflects the innovative development concept. Digital information is a new production factor in the digital economy era. Compared to labor, land, and capital, digital information is easier to achieve reasonable allocation among different regions. At the same time, driven by digital information, labor and capital will also. Transfers between regions have occurred to achieve coordinated regional development. With the increase in the penetration of the Internet and the strengthening of data processing technology, commodity trading locations have gradually shifted from offline to online, reducing the use of resources and improving the utilization of resources; at the same time, more low-carbon and environmentally-friendly industries Produced in the environment has greatly promoted the green development of our economy. The development of the digital economy has strengthened the trade between countries in the international market, increased the export targets of China's commodities, and further improved China's level of opening up. The digital economy is developed based on data information. Data information can be shared through the Internet. All industries and industries can adjust industry development trends in a timely manner based on the shared data information.

Deepen Supply-Side Structural Reforms
The development of the digital economy provides a starting point for adjusting the economic structure, optimizing the allocation of resources in agriculture, industry, and service industries, and creating new industrial chains and new business models. The development of the digital economy has accelerated the digital transformation of various industries, which has a greater impact on the development of agriculture, industry and service industries.
First, the digital economy is conducive to promoting the transformation of agricultural production. In the process of planting crops, digital information L. Wei technology is used to monitor soil quality and environmental climate, and to choose the right time for planting. Use digital equipment to automatically monitor the growth of crops, reduce human labor and increase crop yields. In the aquaculture process, digital technology is used to monitor water quality and growth space in real time, and effectively manage the quantity of aquaculture.
Increase aquatic resources. During the livestock breeding process, the health status of livestock and poultry is digitized, and a livestock information resource database is established to reduce the incidence of livestock and poultry. Combining agricultural production with digital information technology to realize automatic planting of crops, real-time monitoring of the growth environment of aquatic products, and accurate detection of the health of poultry and animals.
Second, the digital economy is conducive to improving the quality of industrial production. At present, China's industrial products are mainly produced by laborers and machines, but in most industrial enterprises, laborers are the main productivity of industrial products, so product quality is easily affected. With the development of the digital economy, digital information technology and industrial production are combined. On the one hand, industrial production is transformed into automation and intelligence to realize large-scale production of products and improve production speed and quality; Accurate docking, providing personalized customization services, and expanding the scale of industrial development.
Finally, the digital economy is conducive to generating new service models.
With the trend of information networking and digitalization, digital services such as online registration, online payment, smart travel, and online shopping have developed rapidly, providing convenience for people to live, eat, live, and travel, and increasingly rely on digital services for daily life.

Promote the Implementation of the Innovation-Driven Development Strategy
The

Improve China's New Competitive Advantage
The digital economy is bound to be a new trend in global economic development. At present, China has an advantage in this regard. Digital service systems in education, medical care, people's livelihood and other aspects are gradually improving, especially in mobile payment, both in terms of payment security, operability, and application coverage are far ahead of other countries. In this era of information digitization, competition between nations will evolve into competition for digital economic capabilities. Internet infrastructure construction, digital information processing capabilities, and integration of digital technologies and industries will all affect the development of a country's digital economy. Therefore, China must seize the new competitive advantages of the information digital era, vigorously promote the development of the digital economy, strengthen the integration of digital technology with various industries, increase the application rate of digital equipment, further open the digital gap with other countries and maintain a leading position and competitive advantage.

Research Status of Digital Economy
The digital economy, as a new economic form based on big data, has a significant impact on the quality of economic growth, industrial upgrades, structural reforms, and the development of new formats. The digital economy has not only attracted the attention of the country, but also attracted the attention of many scholars. Most scholars conduct research around the digital economy.
Tian Li pointed out that countries around the world have different understandings of the connotation of the digital economy, and the focus of developing the digital economy will also be different. Therefore, there are obvious differences in the development goals and strategies of the digital economy [1]. Cao Zhengyong realized that the development of the digital economy would lead to the transformation of China's industrial development model, reshape the value chain of the manufacturing industry, and thus change the mode of economic growth. After researching the digital technology and manufacturing development model, four new models to improve the quality of manufacturing development are proposed: intelligent production and manufacturing model, networked collaborative manufacturing model, personalized customization model, and service-oriented manufacturing model [2]. Cai Yuezhou distinguished the concept of the scale and increment of the value added of the digital economy, and measured the value added of the digital economy in various countries and their contribution to GDP growth [3]. Li Ping believes that the development of the digital economy should be divided into three stages: e-commerce, Internet +, and the transition to digitalization has begun. At different development stages of the digital economy, new business models have emerged, but new business models pose a huge challenge to China's tax system. After studying the taxation governance of new business models in various countries in the world, the taxation governance model of China under the digital economy is proposed [4]. Xu Ji and Tang Qi believe that the digital economy has caused errors in China's national economic accounting. New products, new consumption models, and new income affect consumption accounting in the national economic accounting system. Intangible assets and new investment affect investment accounting in the national economic accounting system. Cross-border flows based on knowledge assets and cross-border e-commerce affect import and export accounting [5]. Gu Tianlong pointed out that the digital economy has led to the construction of new engineering disciplines. China's higher education must change the educational goals and education models for talent training, cultivate new types of talents in line with the development of the digital economy, and improve digital quality [6].
To sum up, Chinese scholars carry out multi-level and multi-angle research on the digital economy in different fields. The research of most scholars is mainly divided into two aspects. One is to focus on the integration of digital economy with traditional industries, and the problems and challenges faced in

Connotation and Characteristics of the Digital Economy
The digital economy takes digital information as the main production factor, and uses the Internet platform to apply digital information processing technologies such as big data and cloud computing to digitize economic activities and economic environments. The digital economy is dominated by the three laws of Metcalfe's Law, Moore's Law, and Davido's Law, and it exhibits features such as Open Journal of Business and Management convenience, high permeability, virtuality, directness, externality, and low cost.

Constructing a Quality Evaluation System for the Development of the Digital Economy
In order to understand the current state of the development of China's digital economy, this article selects basic indicators from three dimensions of science, technology, economy and environment, uses the principal component analysis method to evaluate the quality of China's digital economy development, and explores the problems existing in the development process of digital economy.

Evaluation System Construction
According to the selected indicators, the evaluation system constructed in this paper is shown in Table 1.

Data Analysis
This article selects the data from 2009-2018 to study the quality of digital economy development. After the data is dimensionless processed with SPSS software, the basic indicators are linearly combined using the principal component analysis method based on the correlation matrix to calculate the index value of the secondary indicator, and the principal component analysis is performed on the secondary indicator to measure the development of the digital economy Quality indicator value. Table 2 shows the weights of secondary indicators and the quality indicators of digital economy development.
According to the data in Table 2, the three secondary indicators of technology, economy, and environment have the same change trend as the quality of the   contribution have also verified the rationality of the digital economy development quality evaluation system constructed in this paper. In addition, the data reflects that the quality of China's digital economy development has improved rapidly in the past decade, but compared with developed countries in the same period, China's digital economy development is slightly inferior, indicating that there are still some breakthrough points in the development of the digital economy.

Low Digital Quality of Workers
In the process of integrating digital technology with traditional industries, the low digital quality of workers severely hinders the development of the digital economy. According to data from the National Bureau of Statistics, China's Internet penetration rate has reached 59.6% in 2018, which is far from the Internet penetration rate of developed countries. The low Internet penetration rate indicates that most workers have lower digital quality, have less contact with Internet devices, and lack Internet skills. In the transition from traditional industries to digital development, on the one hand, digital production will replace the positions of low-quality laborers, causing most of the workers engaged in simple and repetitive jobs to lose their jobs; on the other hand, there is a lack of high-quality digital labor capable of using digital production equipment. This has led to slow progress in the digital transformation of the industry.

Unbalanced Development of the Digital Economy
On the one hand, the digital economy is developing unevenly across regions. Affected by the degree of urban and rural development, the two also differ in the level of network infrastructure construction. The development of urban digital economy is significantly better than that in rural areas. On the other hand, the development of the digital economy is uneven among the primary, secondary and tertiary industries. The tertiary industry develops rapidly, but it develops slowly in agriculture and industry. Whether it is the development scale of the e-commerce industry, or the promotion of digital public services such as intelligent travel, illness consultation, and online education, it has demonstrated the active development of the digital economy in the tertiary industry. However, in the development of agriculture and industry, the two take labor and capital as the main factors of production, coupled with the application of digital technology and less investment in digital facilities, resulting in a low degree of integration of digital technology with agriculture and industry, resulting in the digital economy affecting the three industries. There is a significant gap in the contribution of output value. It is this unbalanced development of the digital economy Open Journal of Business and Management that has reduced the quality and speed of digital economy development.

Information Security Risks
User concerns about the leakage of personal information are a key factor limiting the development of the digital economy. On the one hand, e-commerce platforms such as Taobao and JD.com and mobile payment applications such as Alipay and WeChat require real-name registration. Users have doubts about the security of the existing personal information security system and are concerned about the leakage of their personal information, leading to digital applications. The penetration rate is not high. On the other hand, criminals use APPs to collect and steal user information and conduct online fraud, which has a wide range of adverse effects, causing users to resist the use of digital applications. The hidden danger of information security seriously affects the promotion and use of digital applications among residents and hinders the development of digital economy.

Promotion Strategy for Digital Economy Development
Aiming at the current status and challenges of the development of China's digital economy, this article provides improvement strategies from the aspects of strengthening network infrastructure construction, increasing data resources, improving the digital quality of the entire population, ensuring information security, and improving the legal and regulatory system to improve the quality of China's digital economy.

Improve the Level of Network Infrastructure
On the one hand, we will strengthen the construction of network infrastructure in rural areas, increase the number of Internet broadband access ports and the coverage of fiber optic cables, increase rural residents' awareness and use of the Internet, and bridge the "digital divide" between urban and rural areas. On the other hand, according to the needs of rural residents, develop digital applications suitable for rural residents, with the goal of improving the quality of life of residents and convenience of life, so that people's daily lives cannot be separated from digital applications. In order to solve the spatial imbalance in the development of the digital economy, different regions and different classes can enjoy the fruits of the development of the digital economy.

Increase Data Resources
The development of the digital economy is based on digital information as the main production factor. The quantity of digital information and the accuracy of digital information determine the development of the digital economy. Currently, the publicly available databases and the limited data stored in the databases hinder the development of the digital economy. To this end, China should establish a database containing digital information in various fields to ensure the ac-curacy and timeliness of digital information. At the same time, it will explore the operation mode of large-scale data collection, screening, and arrangement, establish a data sharing and exchange platform, promote the open sharing of data resources, and realize the high-quality development of the digital economy.

Improve the Digital Quality of the Entire Population
First, the government combined effective digital applications with current high usage rates to effectively publicize residents and raise their awareness of the digital economy. Secondly, for low-income and low-education workers, digital knowledge and digital skills training will be conducted to improve the digital quality of workers and reduce the number of unemployment in the process of digital transformation of the industry. Finally, colleges and universities should combine the development requirements of the digital economy, speed up the upgrading of talent training programs, integrate the digital economy with related majors, and cultivate high-quality digital talents in the digital age of information.

Improve the Legal and Regulatory System
The digital economy is a product of the era of digital information development.

Improve Information Assurance Security
The disadvantage of digitizing information is that it is easy to cause information leakage, which is also a concern of users of most digital applications. To promote the development of the digital economy, China must establish a sound information security system. On the one hand, it is necessary to formulate a strict information confidentiality system and increase the supervision of information to prevent personal information from being intentionally leaked by e-commerce platforms and mobile payment platforms. On the other hand, layers of protection walls are set up for information, and the information security system is checked from time to time to find loopholes in the information security system and repair them in a timely manner. Only by improving the information security Open Journal of Business and Management system can we increase the utilization rate of digital applications and promote the development of the digital economy.
