The 2018 central economic work conference proposed to accelerate the pace of 5g commerce and strengthen the construction of new infrastructure such as artificial intelligence, industrial Internet and Internet of things. 5g will open a new digital era of interconnection of all things. Industrial Internet is the most important application scenario of 5g. The integrated development of the two has become an important direction for the current industrial exploration 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 an important cornerstone of the fourth industrial revolution. "5g + industrial Internet" is of great significance to accelerate the development of digitization, networking and intelligence, expand and strengthen the digital economy, and promote the integration of digital economy and real economy.

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

With the deepening of a new round of scientific and technological revolution and industrial reform, countries around the world have accelerated the promotion of 5g application, and industry is the key field. At present, China's 5g and industrial Internet have started and developed synchronously with major countries. Actively exploring the integrated application of "5g + industrial Internet" is not only an inevitable choice to comply with the industrial development trend, but also an objective need for China to grasp the historical opportunity of the fourth industrial revolution and take the lead in the new round of global science and technology industry competition.

（2） "5g + industrial Internet" has injected a strong driving force into digital transformation.

5g supports the application scenario from the interconnection of everyone to the interconnection of all things, and expands from the mobile Internet to the interconnection of mobile animals, which can meet the needs of massive information collection, big data processing and remote control. The collection and processing of a large amount of data will gradually narrow the differences in products and services caused by the technical 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, and realize the reconstruction and upgrading of all social production factors, the whole industrial chain and the whole value chain, Boost 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 give birth to new modes and new formats such as smart energy and smart transportation, constantly cultivate new growth points and expand new space, so as to inject inexhaustible power into the development of digital economy.

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

Industrial Internet is the product and specific carrier of the deep integration of the new generation of information and communication technology and the real economy. It integrates advanced achievements in information and communication such as mobile communication, big data and artificial intelligence, and creates an important infrastructure for digital, networked and intelligent development. 5g has the characteristics of high rate, low delay and large connection, which is highly consistent with the needs of industrial Internet connection diversity, performance differentiation and communication diversification. It is a key enabling technology for the evolution and upgrading of industrial Internet network. The integrated development of 5g and industrial Internet will accelerate the building of a new generation of high-speed, intelligent, ubiquitous, safe and green 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" has accelerated

In recent years, China's domestic industry has always been driven by innovation and development, adhered to the combination of enterprise subject and government guidance, independent innovation and open cooperation, and accelerated the R & D and industrialization of 5g and industrial Internet. With the joint efforts of government, industry, University, research and application parties, China's "5g + industrial Internet" continues to make new progress, the integration effect is beginning to show, and the development prospect is broad.

（1） The industrial foundation has been continuously consolidated.

On the one hand, 5g development 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 R & D, Huawei, ZTE and other enterprises take the lead in intermediate frequency system equipment; Hisilicon took the lead in releasing the first 5g base station core chip and multi-mode terminal chip. In terms of network construction, as of November 21, 2019, 113000 5g base stations have been opened in China, and it 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, the construction of industrial Internet has made positive progress. Manufacturing enterprises actively use new network technology to carry out factory intranet transformation, and basic telecom enterprises speed up the construction of high-quality external benchmarking network; Five national top-level nodes have been built and operated, and the number of logo registrations has reached 1.1 billion; The number of platforms with certain industry and regional influence exceeds 50, 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 national, provincial and enterprise level linkage security system has been accelerated. It has been connected with 12 provinces, covering 91000 enterprises and monitoring 135 industrial Internet platforms.
