The 2018 Central Economic Work Conference proposed to speed up the pace of 5G business and strengthen the construction of new infrastructure such as artificial intelligence, industrial Internet and the Internet of Things. 5G will usher in a new digital era of the Internet of Things. The industrial Internet is the main application scenario of 5G. The integration and development of the two has become an important direction for the current industry to explore, and will have a significant impact on China's economic and social development.

1、 The development of "5G+industrial Internet" is of great significance

5G is the key support for digital transformation, and the industrial Internet is the important cornerstone of the fourth industrial revolution. "5G+industrial Internet" is of great significance to accelerate the development of digitalization, networking and intelligence, to make the digital economy bigger and stronger, and to promote the integration of the digital economy and the real economy.

（1） "5G+Industrial Internet" is an inherent requirement to comply with the trend of global industrial change.

With the deepening of the new round of scientific and technological revolution and industrial transformation, countries around the world have accelerated the promotion of 5G applications, with industry as the key area. At present, China's 5G and industrial Internet have achieved the simultaneous start and synchronous development with major countries. Actively exploring the integrated application of "5G+industrial Internet" is not only an inevitable choice to comply with the trend of industrial development, but also an objective need for China to seize the historical opportunity of the fourth industrial revolution and take the lead in the new round of global scientific and technological industry competition.

（2） The "5G+Industrial Internet" has injected a strong drive into the digital transformation.

The 5G support application scenario extends from the Internet of Everyone to the Internet of Everything, and from the mobile Internet to the Internet of Mobile Animals, which can meet the needs of massive information collection, big data processing and remote control. The collection and processing of large amounts of data will gradually narrow the product and service differences caused by the technology gap. The integrated application of "5G+Industrial Internet" in the vertical field will drive the digital expansion of industry, form new organizations, new products and new models centered on intelligence in the industrial field, promote the improvement of quality and efficiency and the optimization of economic structure by providing high-quality services, realize the reconstruction and upgrading of all elements of social production, the whole industrial chain and the whole value chain, and help the digital transformation and development of the real economy. With the gradual penetration of "5G+industrial Internet" into agriculture, service industry and other fields, it will promote the emergence of new models and new business forms such as smart energy and smart transportation, constantly cultivate new growth points, expand new space, and inject inexhaustible power into the development of the digital economy.

（3） "5G+Industrial Internet" accelerates the evolution and upgrading of new infrastructure.

The industrial Internet is the product and concrete carrier of the deep integration of the new generation of information and communication technology and the real economy. It integrates advanced information and communication achievements such as mobile communication, big data, artificial intelligence, and creates an important infrastructure for the formation of digital, networked and intelligent development. 5G has the characteristics of high speed, low latency and large connectivity, which is highly compatible with the requirements of industrial Internet connectivity diversity, performance differentiation and communication diversification, and is the key enabling technology for the evolution and upgrading of industrial Internet networks. The integrated development of 5G and industrial Internet will accelerate the building of a high-speed, intelligent, ubiquitous, safe and green new generation of information network, further improve the intelligent level of traditional infrastructure, build new infrastructure, and support the high-quality development of entities.

2、 China's exploration of "5G+industrial Internet" accelerated

In recent years, China's domestic industry has always been driven by innovation and development, adhered to the combination of enterprise main body and government guidance, independent innovation and open cooperation, and accelerated the development and industrialization of 5G, industrial Internet, etc. With the joint efforts of the government, industry, university, research and application parties, China's "5G+industrial Internet" has made new progress, and the integration effect has begun to show, with broad prospects for development.

（1） The industrial foundation has been constantly consolidated.

On the one hand, the development of 5G continues to accelerate. In terms of standard formulation, as of May 2019, the number of patents declared by Chinese enterprises accounted for more than 30% of the global total. In terms of product research and development, Huawei, ZTE and other enterprises have advanced mid-band system equipment; Hisense took the lead in releasing the first 5G base station core chip and multimode terminal chip. In terms of network construction, as of November 21, 2019, 113000 5G base stations have been opened nationwide, which is expected to reach 130000 by the end of the year. In terms of application promotion, actively promote the application of 5G in industrial Internet, Internet of Vehicles, ultra-high-definition video, smart city and other fields. On the other hand, positive progress has been made in the construction of industrial Internet. Manufacturing enterprises actively use the new network technology to carry out the transformation of the factory intranet, and basic telecommunications enterprises accelerate the construction of high-quality enterprise external benchmarking network; Five national top nodes have been built and operated, and the number of logo registration has reached 1.1 billion; There are more than 50 platforms with certain industrial and regional influence. The average number of industrial equipment connections of key platforms exceeds 650000, the average number of registered users is 500000, and the average number of industrial APPs is 1950; The construction of a three-level linkage security system at the national, provincial and enterprise levels has been accelerated. It has been connected with 12 provinces, covering 91000 enterprises and monitoring 135 industrial Internet platforms.
