According to the latest data of the Ministry of Industry and Information Technology, the scale of China's industrial Internet industry is expected to reach 1.2 trillion yuan in 2022, providing strong support for high-quality economic and social development. The reporter learned from many aspects that China will further improve the top-level design, make full use of relevant fiscal, tax and financial policies, promote enterprises to actively use 5G and other technologies to carry out factory digital transformation, accelerate the large-scale development of industrial Internet, promote the deep integration of the digital economy and the real economy, and constantly release the power of industrial upgrading. Empowering the transformation and upgrading of traditional industries is the key path to promote the deep integration of the digital economy and the real economy. The industrial Internet continues to release its effect in promoting the transformation and upgrading of traditional industries. The industrial Internet identity resolution system is the foundation of the industrial Internet network system and an important link to support the industrial Internet. In 2022, China's industrial Internet identity resolution system will be fully completed. Zhao Zhiguo, director of the Information and Communication Administration Bureau of the Ministry of Industry and Information Technology, said that at present, the five national top nodes and two disaster recovery nodes in the east, west, north, south and middle regions have all been online, the secondary nodes have achieved full coverage, serving nearly 240000 enterprises, and cultivating more than 240 influential industrial Internet platforms, including 28 cross-industry and cross-domain platforms, which have effectively promoted the data exchange and resource coordination of the entire product process, all links of production, upstream and downstream of the supply chain, Accelerate the digital transformation of enterprises. From the perspective of the transformation of the enabling industry, China has created a number of application promotion service carriers, cultivated "low-cost and lightweight" solutions, and lowered the threshold of digital transformation of enterprises, especially small and medium-sized enterprises. "We focus on the characteristics of various industries, develop and promote industrial Internet integration application guidelines for more than 10 key industries, such as steel and electronics, and guide industrial enterprises to carry out industrial Internet applications according to industry and enterprise conditions. We implement the industrial Internet innovation and development project, accelerate the research and industrialization of key technology products, and release a number of national, industrial and group standards, further improving the standard system," Zhao Zhiguo said. It is worth mentioning that in the construction and application of "5G+Industrial Internet", China has built more than 4000 "5G+Industrial Internet" projects in more than 10 key industries such as automobile and mining, and accelerated the popularization in 20 typical application scenarios such as collaborative R&D design and remote equipment control, which has effectively promoted enterprises to improve quality, reduce cost and increase efficiency. Zhao Zhiguo said that the industrial 5G integration products are increasingly rich, and the module price is 80% lower than the initial commercial stage. The construction boom of 5G fully connected factories has been set off around the country, accelerating the further deepening and expansion of 5G to the core control link of production. In the view of industry insiders, the development of industrial Internet in China is in the critical period of starting exploration and turning to scale development, but there are still challenges to improve the coverage and application depth of industrial Internet. Zhao Gang, president of Saizhi Industrial Research Institute, believes that in terms of the applicability of the platform, there are many types of industrial enterprises, and the process flow is complex. How the general industrial Internet platform can adapt to the application needs of different enterprises needs further exploration. In terms of system application, the production equipment of industrial enterprises may come from different manufacturers, the equipment interface standards are not uniform, and some systems are relatively closed, which puts forward higher requirements for system integration.
