The digital economy is a new economic form that relies on data resources as key elements, modern information networks as the main carrier, and the integration and application of information and communication technology, as well as the transformation of all factor digitization as important driving forces. In recent years, the rapid development, wide penetration, and profound impact of the digital economy have become unprecedented, and it is becoming a key force in restructuring global factor resources, reshaping the global economic structure, and changing the global competitive landscape. General Secretary Xi Jinping pointed out that "developing the digital economy is of great significance and is a strategic choice to seize the new opportunities of the new round of technological revolution and industrial transformation." China's digital economy has achieved remarkable results, ranking second in the world in terms of overall scale for consecutive years, and the core industry has grown rapidly, becoming an important force in promoting high-quality development. The Decision of the Third Plenary Session of the 20th Central Committee of the Communist Party of China proposed to accelerate the construction of a system and mechanism to promote the development of the digital economy and made important arrangements, which pointed out the direction for further promoting the development of the digital economy. To study and implement the spirit of the Third Plenary Session of the 20th Central Committee of the Communist Party of China, we must deeply understand the significant significance of developing the digital economy and promote the healthy development of China's digital economy. Beneficial for improving the efficiency of resource allocation. The digital economy can promote the rapid flow of various resource elements, accelerate the integration of various business entities, help business entities reconstruct organizational models, break time and space limitations, achieve cross-border development, and have unique advantages in improving the efficiency of resource element allocation. For example, the collection, processing, and analysis of massive data can fully reveal market information, promote precise resource allocation and dynamic adjustment, thereby improving utilization efficiency, reducing resource consumption, and environmental pollution; For example, with the development and growth of the platform economy, different business entities can more conveniently access and use resources through the platform. While achieving resource sharing and recycling, improving social benefits, it can also reduce operating costs and enhance economic efficiency. Focusing on improving the efficiency of resource allocation, we need to build and operate a national data infrastructure to promote data sharing; Accelerate the establishment of a system for determining the ownership of data property rights, conducting market transactions, distributing rights and interests, and protecting interests, enhance the capacity for data security governance and supervision, and establish an efficient, convenient, and secure mechanism for cross-border data flow; Promote innovative development of platform economy and improve the normalized regulatory system for platform economy. Beneficial for building a modern industrial system. The digital economy has high innovation, strong penetration, and wide coverage, and can become an important engine for building a modern industrial system. The development of the digital economy can promote the intelligent production process, information-based management mode, personalized product and service transformation of traditional industries, improve the production efficiency and product quality of traditional industries, and promote the transformation and upgrading of traditional industries; It can give birth to new industries and formats, such as e-commerce, digital finance, online education, remote healthcare, etc., greatly enriching economic formats and business models, and promoting the diversification and upgrading of the economic structure; It can promote the development of the industrial chain towards networking and platformization, help enterprises strengthen close cooperation and collaborative innovation with upstream and downstream enterprises, and improve the overall operational efficiency and competitiveness of the industrial chain. To this end, it is necessary to improve the system for promoting the deep integration of the real economy and the digital economy, give full play to the amplification, superposition, and multiplication effects of digital technology on economic development, cultivate and strengthen advanced manufacturing clusters, build a number of industry common technology platforms, accelerate the transformation of industrial models and enterprise organizational forms, improve the institutional mechanisms for enhancing the leading position of advantageous industries, and accelerate the construction of a modern industrial system. Beneficial for building new competitive advantages for the country. Implementing the innovation driven development strategy is an inevitable requirement and strategic measure to accelerate the transformation of the economic development mode, enhance China's comprehensive national strength and international competitiveness. The rapid development of the digital economy has not only given birth to a large number of new formats and models, but also made innovation no longer limited to a certain field or industry, showing a trend of cross-border integration and collaborative innovation, further enhancing the overall efficiency of innovation. Taking the development of the digital economy as an important lever and grasping the "bull's nose" of independent innovation in key digital core technologies is conducive to achieving high-level technological self-reliance and building new competitive advantages for the country as soon as possible. On the new journey, we need to focus on improving our basic research and development capabilities in information technology, win the battle against key core technologies, accelerate the all-round and full chain popularization and application of the new generation of information technology, and seize the high ground of future development. At the same time, strengthen basic research to provide more solid theoretical support and technological source supply for the development of the digital economy. (New Society)
