As an important cornerstone and new infrastructure of the fourth industrial revolution, the industrial Internet provides key support and engine for accelerating the digital transformation of enterprises. The industry said that with the joint issuance of the 14th five year plan for intelligent manufacturing development by the Ministry of industry and information technology and other eight departments, the digital transformation of the manufacturing industry has become the general trend. Under the background of the continuous evolution of a new round of scientific and technological revolution and industrial reform, and the deep integration and development of the digital economy and the real economy, the industrial Internet is a strong support for the development of the manufacturing industry and a key support for the high-quality development of the real economy. However, considering that the industrial Internet needs a complete infrastructure to support it, and China's industrial infrastructure is being built and promoted at this stage, experts suggest that the next step to promote the development of the industrial Internet should be to play a "combined fist" of policies and promote the implementation of policy coordination and integration between central and local governments, while giving full play to the positive role of manufacturing enterprises, ICT enterprises and other relevant service providers to drive the whole industrial chain The innovation chain plays an active role. Keep going deep to reality In recent years, with the intensive implementation of a series of orderly policies and measures, the integrated application of industrial Internet in China has been deepening to reality. According to the data of the Ministry of industry and information technology, the scale of China's industrial Internet industry has exceeded trillion yuan. In terms of industry, the industrial Internet has been applied in 45 categories of national economy; From the perspective of industry, the industrial Internet not only promotes individual enterprises to improve quality, reduce cost and increase efficiency, but also drives the upstream and downstream of the industrial chain to operate in a coordinated and efficient manner; In terms of links, the industrial Internet has been widely used in R & D and design, manufacturing, operation management and other links, especially 5g is accelerating its extension to production control. Driven by the industrial Internet, enterprises have accelerated the pace of "cloud" and "number". Wangjianwei, deputy director of the information technology development department of the Ministry of industry and information technology, introduced that as of March this year, the CNC rate of key processes in China's Industrial Enterprises above Designated Size and the popularity of digital R & D and design tools had reached 55.5% and 75% respectively, and the proportion of manufacturing enterprises and service-oriented manufacturing enterprises that carried out networked collaboration had reached 39.2% and 29.9% respectively. The digital transformation has obvious effects of improving quality, reducing cost and increasing efficiency. It is worth mentioning that in recent years, China's industrial Internet enabled industrial digital transformation has also achieved remarkable results. According to the data of the ICT Institute of the Ministry of industry and information technology, as of the first quarter of 2022, China has more than 150 influential industrial Internet platforms, and the total number of "5g+ industrial Internet" projects under construction has reached 2400, which has continuously enhanced the support capacity for the digital transformation of manufacturing enterprises; Industrial Internet applications have covered more than 40 key industries of the national economy. The mode of industrial digital transformation has changed from single point of application to comprehensive integration. The transformation content has extended from peripheral production links to high-value links, and continues to give birth to new models and new business forms. Promote economic development According to weiyiyin, an academician of the Chinese Academy of engineering, "Data-Driven intelligent manufacturing, collaborative manufacturing and cloud manufacturing based on the industrial Internet platform are becoming an important path for the transformation and upgrading of the manufacturing industry". Weiyiyin said that considering that digital transformation is an important starting point to promote the high-quality development of China's industry, as an important cornerstone and new infrastructure of the fourth industrial revolution, the industrial Internet provides a key support and engine for accelerating the digital transformation of enterprises, which is not only a key path to promote China's industrial digital transformation, but also a key support to promote the high-quality development of the real economy. Yubin, member of the leading Party group and deputy director of the development research center of the State Council, said, "we should comply with the development trend of a new round of industrial revolution, accelerate the construction and popularization of new infrastructure with the industrial Internet as the core, reshape China's new industrial competitive advantage in promoting digital transformation, and lay a solid foundation for the high-quality development of China's economy.". Deep ploughing still needs to be strengthened In weiyiyin's view, China's industrial Internet has entered a critical period of industrial deepening, and there are still many practical problems in promoting the digital transformation of manufacturing industry through the industrial Internet. Weiyiyin raised the following issues: first, data privacy protection, data right confirmation, data asset valuation and data security circulation; Second, the standardization of industrial Internet platform financing, and the lack of standard support for platform "application, resources and data" financing; Third, the problem of industrial application and promotion. The supply of new industrial software based on industrial knowledge precipitation is insufficient, and the development cycle of new fields and industries is long, resulting in difficulties in application replication. Considering that China's industry has a large volume, a large number of categories, a low level of digitalization, a large diversity of needs, and the development of industrial Internet needs to be closely combined with industry-specific technology, knowledge and experience, which has the characteristics of high complexity and long time, weiyiyin suggests that, "While strengthening legislation, improving policies, breaking through technologies, enriching products, innovating models and strengthening applications, we need to make better use of the industrial Internet to realize industrial digital transformation and promote its development in depth". Zhangjiefei, director of the industrial planning department of the Policy Institute of the China Industrial Internet Research Institute, suggested that, in view of the fact that the industrial Internet needs a complete infrastructure to support it, China's industrial infrastructure is being built and promoted at this stage. In the next step, promoting the industrial Internet needs to play a "combined fist" of policies and promote the implementation of policy coordination and integration between central and local governments; Carry out multi-party "team competitions", give play to the positive role of relevant service providers such as manufacturing enterprises and ICT enterprises, and give play to the positive role of the whole industrial chain and innovation chain; We will carry out the "battle to tackle tough problems" of innovation, promote industrial technological breakthroughs through the cooperation of industry, University, research and application, and further deepen and consolidate the industrial foundation. At the same time, longguoqiang, member of the leading Party group and deputy director of the development research center of the State Council, also said that in the next step of developing the industrial Internet, while strengthening the research on the theory of digital economy, we also need to have a global vision and strive to build an industry leading enterprise with international competitiveness.
