Through years of continuous and in-depth promotion of smart city construction and the accelerated empowerment of multiple new technologies, China is actively building an upgraded version of smart cities. From building various independent "point like" information systems, to providing "line by line" digital applications and services based on management functions, to gradually exploring and promoting cross departmental, cross business, and cross system "surface" integrated applications, China's smart city construction has achieved rapid development through exploration and practice in various regions.

In recent years, the scale of investment in smart city construction in China has been continuously expanding. According to IDC's prediction, the investment scale of China's smart city ICT (Information and Communication Technology) market will exceed 870 billion yuan in 2023, and by 2027, the investment scale of China's smart city ICT market will exceed 1.1 trillion yuan. Various regions in our country are actively exploring the practice of smart cities.

The overall layout plan for the construction of Digital China clearly states the need to connect the major arteries of digital infrastructure. This provides strong support for the digital transformation of urban governance. According to the data of the Ministry of Industry and Information Technology, by the end of May this year, China had built a total of 3.837 million 5G base stations, accounting for more than 60% of the total 5G base stations in the world. The scope of Internet applications has continued to expand, IPv6 resources are abundant, and the scale of computing infrastructure has reached the forefront of the world.

The comprehensive layout of these new basic elements and the integration of new technologies provide new impetus for urban governance and smart city construction in China.

Yu Xiaohui, President of the China Academy of Information and Communications Technology, stated that 5G has penetrated into most of China's national economy and industry sectors to enhance production efficiency. It is predicted that China will further amplify the empowering role of 5G in various fields of the economy and society, and the combination of 5G and technologies such as artificial intelligence will also grow into a new growth curve

Supporting online Q&A anytime and anywhere, processing large amounts of environmental data in real-time, predicting traffic flow at different times... From the key application scenarios of urban construction in China, large models have technological advantages such as fast and accurate identification, logical deduction, and predictive judgment, and have been integrated into various fields such as urban grassroots governance, public safety, and traffic management.

Chen Fengxian, Senior Analyst at the Strategic Development Research Institute of China Telecom Research Institute, stated that the service hotline platform built on a large model has significantly improved the timeliness of public consultation services, greatly reduced online queuing time, and increased service efficiency by 30%.

The integration of Beidou and 5G is becoming a new hotspot in the construction of smart cities, and low altitude economy is regarded as the "new infrastructure" of smart cities
