The recently held 2023 China 5G+Industrial Internet Conference released a set of data: China's 5G+industrial Internet projects have reached 8000, covering all 41 major categories of industry, and the proportion of 5G applications in the industrial field exceeds 60%. At the same time, the purchase price of 5G base stations by operators has decreased by 53% compared to the initial development of 5G+industrial internet, and the cost of key components has decreased by 90%. From this, it can be seen that the idea of "promoting use through construction and using to lead construction" has achieved good results. 5G and industrial internet are both important driving forces for achieving digital transformation of the economy and society. Among them, the Industrial Internet is not a simple application of the Internet in the industrial field, but a new infrastructure, application mode, and industrial ecology that deeply integrates new generation information technologies such as 5G, big data, and artificial intelligence with the industrial economy. It is the key support for the Fourth Industrial Revolution. 5G is an important direction for the evolution and upgrading of the new generation of information and communication technology, and is a leader in new infrastructure. Compared with previous mobile communication technologies, 5G has the characteristics of high speed, low latency, wide coverage, and connectivity. It can further amplify its role as an engine of the digital economy and is more suitable for industrial internet. The two can be said to be a "perfect match". The integration of 5G and industrial internet is moving from addition to multiplication. Practice has proven that the integration and innovative development of 5G and industrial Internet can not only promote the transformation of manufacturing industry from single point and local information technology applications to overall digitization, networking, and intelligence, but also open up broader market space for 5G, effectively supporting the construction of a manufacturing and network power. Currently, more than half of China's 5G+industrial internet applications are in the industrial sector, and its application scope continues to extend to the core links of production and manufacturing, moving from simple additive effects to multiplier effects of superposition and multiplication. The potential for application is constantly being released, which also stimulates more new formats and models. It should be noted that fusion is not simply a combination of technologies. The integration of 5G and industrial internet needs to move from "one-way empowerment" to "two-way travel". This includes technology integration, such as the deep integration of 5G technology and industrial control system, the integration and innovation of 5G+industrial Internet and new technologies such as artificial intelligence, edge computing, blockchain, etc., to produce "nuclear fusion" and create real "killer" applications; This also includes the integration of modes, such as the transformation of the integration mode from "single point demonstration" to "factory integration", the evolution of enterprise deployment from "local breakthroughs" to "industrial cluster development", continuously promoting the breadth and depth of integration, and cultivating 5G+industrial Internet characteristic industries. Integration cannot be separated by supply and demand. According to reports, the prices of industrial 5G chips, modules, and gateways are currently showing a significant downward trend, especially the price of 5G universal modules has dropped to over 200 yuan. However, the overall cost is still higher than expected by small and medium-sized enterprises, and there is still room for further decline. On the one hand, it is necessary to accelerate the research and promotion of industrial grade 5G products, improve the supply level of 5G industrial equipment, and drive quality improvement and cost reduction through large-scale application; On the other hand, it is necessary to strengthen application traction, focus on solving practical problems for enterprises, and truly bring benefits to enterprises in order to attract more enterprises to invest in applications and promote the resolution of cost problems. Integration also needs to be promoted in different industries and levels. Public data display, objective
