[Li Xiang China] Promoting high-quality development with the digital economy

　　At present, China’s economy has changed from a high-speed growth stage to a high-quality development stage, and high-quality development is the primary task of building a socialist modern country in an all-round way. Digital economy has high innovation, strong permeability and wide coverage. It is not only a new economic growth point, but also a fulcrum for transforming and upgrading traditional industries, and can become an important engine for building a modern economic system.

　　With the rapid development of next-generation information technologies such as Internet of Things, cloud computing and artificial intelligence, digital economy has increasingly become a key force to reorganize global factor resources, reshape the global economic structure and change the global competition pattern. In the development history of human society, every industrial and technological revolution will promote the change of production mode, and then lead to the change of the world economic structure.

　　In the new journey of building a socialist modern country in an all-round way, seizing the opportunity of digital economy development and vigorously promoting digital industrialization and industrial digitalization are the key links to promote high-quality development and build a socialist modern power in an all-round way.

　　The rise of digital economy has triggered great changes in the mode of economic development. As a brand-new economic form, its development is an inevitable requirement to promote the high-quality development of China’s economy. The author believes that the digital economy promotes high-quality development, which is mainly reflected in four aspects. First, the digital economy improves production efficiency and promotes high-quality development. As a factor of production, data, in the process of integration into production, can make production more scientific and division of labor more precise by changing the combination mode of traditional factors, so as to improve production efficiency. Second, the digital economy improves the efficiency of resource allocation and promotes high-quality development. The digital platform has a huge amount of data. Through data cleaning and analysis, the accuracy and pertinence of the input can be improved, thus reducing the cost, reducing the waste of resources and improving the surplus of consumers and producers. Third, the digital economy promotes transformation and upgrading to promote high-quality development. Digital technology optimizes the production and management methods of industries, expands the division of labor boundaries of industrial chain organizations, promotes the deep integration of digital economy and real economy, improves the operational efficiency of industrial organizations, and provides new opportunities for the innovative development, transformation and upgrading of real economy. Fourth, the digital economy improves governance capacity and promotes high-quality development. The application of big data promotes the transformation of government functions from social management to social service, and the use of big data in national governance optimizes the way of people’s livelihood service and enhances the scientific decision-making and timeliness of action.

　　At present, China’s digital economy is booming and has made remarkable achievements. It is necessary to promote the development of the digital economy in all directions and in multiple dimensions to continuously strengthen and improve China’s digital economy and give full play to its important role as a new engine for high-quality development.

　　Adhere to the system layout and accelerate the release of the potential of data elements. The "Tenth Five-Year Plan for Digital Economy Development" issued by the State Council proposes to "make good use of data elements" and "fully release the value of data elements and activate their potential". As an important part of digital economy, data elements are combined with traditional elements such as land, labor and capital to empower all aspects of social reproduction and accelerate the transformation of production mode, consumption mode and economic structure. With the characteristics of non-competitiveness, non-consumption, virtuality and economies of scale, data elements will surely become the key to promote industrial upgrading and high-quality development. To stimulate the innovation potential of data elements, it is necessary to strengthen the top-level design for enabling high-quality development of data elements, optimize the environment for the integration of data elements and other production factors, improve the policies and regulations for data confirmation, sharing and market circulation, promote the reform of data supply side, cultivate data-driven enterprises, improve the scale and quality of data supply, timely introduce incentive policies, actively cultivate market demand, and establish and improve a unified national data element market.

　　Adhere to self-reliance and accelerate the breakthrough of core technologies. Accelerating the realization of high-level scientific and technological self-reliance is the only way to promote high-quality development. In the fierce international competition, we have to open up new fields, new tracks, new kinetic energy and new advantages. Fundamentally speaking, we still have to rely on scientific and technological innovation. On the one hand, China is in the critical period of building a socialist modern country in an all-round way, and it depends on scientific and technological innovation to empower high-quality development, and the digital economy field is one of the most active fields of scientific and technological innovation at present. On the other hand, there are still "stuck neck" problems of high-end chips, core algorithms and frameworks, cloud computing systems and other technologies in China’s digital technology, and the technical base of digital economy is not solid enough. To accelerate the breakthrough of core technology, we need to give full play to the advantages of China’s socialist system, new national system and super-large-scale market, aim at strategic and forward-looking fields, concentrate high-quality resources to promote core technology research and improve the efficiency of independent research and development; Build an integrated digital technology innovation and application chain in Industry-University-Research, form an innovation consortium, and enhance the R&D power of core technologies.

　　Insist on strengthening the foundation and solidly promote the construction of new infrastructure. New infrastructure is the basic support for the digital economy to play a multiplier effect, an indispensable basic element and material condition for achieving high-quality development, and a necessary guarantee for building a modern economic system and a socialist modernization power. It is necessary to strengthen the strategic layout and accelerate the construction of a high-speed ubiquitous, integrated heaven and earth, cloud network integration, smart and agile, green and low-carbon, safe and controllable intelligent comprehensive digital information infrastructure based on 5G network, national integrated data center system and national industrial Internet. Strengthen the reform of institutional mechanisms, make overall plans, adjust measures to local conditions, and scientifically and orderly lay out new infrastructure. Grasp the innovation-driven strategy, adhere to the demand-oriented, problem-oriented, goal-oriented and carry out construction as needed. Give full play to the market resource allocation mechanism, market-led, multi-party coordination to promote construction. Grasp the development law of new infrastructure and promote its implementation by classification. Strengthen public opinion supervision and information disclosure, gradually liberalize investment market access, and broaden financing channels.

　　Adhere to the integration of "number and reality" and promote the digital transformation of the industry. Report to the 20th CPC National Congress of the Party emphasized: "Accelerate the development of the digital economy, promote the deep integration of the digital economy and the real economy, and build a digital industrial cluster with international competitiveness." The integration of digital economy and real economy is not only the objective law of social development and the natural choice of economic growth, but also an important task of high-quality development. Use digital technologies such as big data and artificial intelligence to promote all-round and full-chain transformation of manufacturing, service and agriculture industries, improve total factor productivity, and give play to the amplification, superposition and multiplication of digital technologies on economic development. Gradually explore the "digital and real" integration platform of different industries and different enterprise scales, provide public services for the digital transformation of various enterprises, and cultivate the digital ecology of excellent industries. Strengthen cross-regional integration and cooperation, give play to the development advantages of each region in the digital economy, and strive to build a development pattern of co-construction, sharing and win-win.

　　Adhere to standardized governance and constantly improve the digital economy governance system. The digital economy governance system provides policy support for the digital economy to empower high-quality development. A safe and reliable digital governance system is a necessary condition to ensure the healthy development of digital economy, improve the ability and level of digital economy governance and promote the modernization of digital economy governance system.

　　It is necessary to uphold the scientific and pluralistic concept of collaborative governance, clarify the responsibilities and roles of the government, enterprises and public subjects in the collaborative governance system, and work together and cooperate with each other. Improve the market access system, fair competition review system and fair competition supervision system, clarify the responsibility boundary, and clarify the responsibilities and obligations of large Internet platforms. Strengthen the early warning and monitoring of digital governance risks, make emergency plans, and effectively prevent potential risks of digital governance.

　　The digital economy is related to the overall development of the country. We have the confidence and ability to seize the opportunity and win the initiative in the new round of scientific and technological revolution and industrial transformation with digital technology as the core, promote the digital economy to better serve and integrate into the new development pattern, and accumulate energy for achieving high-quality development.
