Vigorously developing the digital economy is a clear requirement put forward by the Central Economic Work Conference. Since the 18th National Congress of the Communist Party of China, China's digital economy has achieved remarkable development achievements. Its overall scale has ranked second in the world for many consecutive years, and its leading and supporting role in economic and social development has become increasingly prominent. How to further accelerate the development of digitalization and create new advantages of the digital economy on the basis of the current situation has become the issue. Looking around the world, with the further development of the new round of scientific and technological revolution and industrial transformation, the digital transformation has been further advanced, the traditional industry has accelerated its transformation and upgrading to the direction of intelligence, green and integration, the new industry, new business forms and new models have flourished, and the mode of production and lifestyle have undergone profound changes. For example, the input of digital capital in the digital economy has effectively promoted the improvement of production efficiency in various industries, forming a new and higher level of productivity. In the industrial field, the electronic information manufacturing industry plays an important role in improving the production efficiency of other industries through the improvement of its own production efficiency and its own products as intermediate inputs, making a high contribution to the improvement of industrial total factor productivity, far exceeding the proportion of the electronic information manufacturing industry in industrial added value. However, the problems existing in the development of China's digital economy can not be ignored, especially in the lack of innovation capacity in key areas, and the relatively slow development of traditional industry digitalization. The data shows that the average value of Caixin Digital Economy Index from January to October 2022 was 450, down 17.9% year on year, lower than the same period in 2019. The existence of these problems is related to the shrinking of internal and external markets and the insufficient strength of industrial digital transformation. For example, from the perspective of the specific practices of digital transformation, there is currently a lack of applicable digital transformation solutions. Enterprises often need to develop their own digital solutions and build their own systems, and the trial and error costs are high. Digital investment is also insufficient. Some enterprises' digital investment only digitizes a small number of production and operation links, which is not fully integrated with the existing production and operation processes, and the scope economic effect of digitalization is difficult to fully play. To effectively solve these problems, we must adhere to the goal orientation and problem orientation, firmly grasp the initiative of digital technology development, and take multiple measures simultaneously. We should further implement the new infrastructure construction project and continue to promote the large-scale deployment and integrated application of 5G networks. Focus on key areas such as artificial intelligence and advanced computing, and cultivate a number of eco-leading enterprises with key core technologies and international competitiveness. It is necessary to release the amplification, superposition and multiplication effect of digital on economic development, deepen the integrated development of "5G+industrial Internet", promote the construction of 5G fully connected factories, and accelerate the cultivation of "specialized, special and new" enterprises and single champion enterprises in the manufacturing industry. We should continue to deepen the research on the development law of the digital economy, coordinate development and security, improve the system, establish a classified and hierarchical management system for industrial Internet security, actively participate in international cooperation in the digital economy, and promote the construction of a community of shared future in cyberspace.
