At present, the digital economy has become the "commanding heights" of many countries in the world competing to seize the initiative in future economic development, what are the characteristics and potential of the development of China's urban digital economy? Why has smart city become an important support for the national economic operation system?
On December 13, a set of data presented by the "China Urban Digital Economy Forum 2021" hosted by the Shanghai Terminus of the Central Radio and Television Corporation said that according to the China Academy of Information and Communications Technology, in 2020, China's digital economy ranked second in the world, with a scale of 39.2 trillion yuan (5.4 trillion US dollars), accounting for 38.6% of GDP.
At the forum, Hu Jianbo, vice president of the China Communications Research Institute, said at the release of the "Report on the Development of China's Urban Digital Economy" (hereinafter referred to as the "Report") that overall, the cities with high competitiveness of China's digital economy are concentrated in the southern and eastern regions, and Beijing, Shanghai and Shenzhen are located in the first echelon of China's digital economy competitiveness.
The "Report" shows that in the national ranking of the digital economy competitiveness index in 2020, from the perspective of east-west distribution, 12 cities in the eastern region are in the top 15 cities, and from the north-south distribution, the top 15 cities are 12 in the south. Large regional differences are presented.
Wu Zhiqiang, an academician of the Chinese Academy of Engineering, explained that China's cities have a wide distribution space and large differences in resource endowments, so the development in the field of digitalization is extremely uneven. Looking at the history of the development of world cities, it can be divided into four stages, the first stage of the city is to provide a place for the exchange of goods; the second stage of the city becomes a gathering place of resources, but does not produce resources itself; the third stage is to enter the industrial revolution, the city with the help of chemical raw materials to produce a large amount of material wealth. Now, the city has entered the 4.0 stage, and the intellectual innovation of the digital and brain determines the quality of urban development. How many cities can enter the "intellectual city" determines whether the whole country can smoothly enter the 4.0 stage.
Wu Zhiqiang pointed out that in the current world, the four stages of human cities coexist, which can be divided into trading cities, material cities, physical (resource) cities, and intellectual cities. "'Intelligence' is the determinant of the quality of cities today, and all cities around the world will be screened as a result."
According to the competitiveness of digital economy cities, the "Report" divides the national cities into three categories: comprehensive leading, characteristic pioneering and potential improvement. Among them, Beijing, Shanghai and Shenzhen have a high strategic positioning of digital economy construction, which is the comprehensive leading city of China's digital economy, which is mainly manifested in the characteristics of huge digital economy, rich innovation elements, complete infrastructure, rich digital formats, strong digital demand, perfect policy support, and obvious driving role of digital economy, which have a leading role in the development of the digital economy in the country.
What challenges do different types of cities face in developing the digital economy?

He Jifeng, an academician of the Chinese Academy of Sciences, pointed out in an exclusive interview with a reporter from China News Network during the forum that at present, such as Shanghai, Beijing and other megacities, there is a good information infrastructure, and based on the data and platform on it, it can play a good role in the fine governance of the city, but the comprehensive construction of information infrastructure nationwide still needs a process. For the first-mover large cities, "informatization should also be limited, not only to achieve the goal of social governance, but also to let the people feel humanized, and to balance technology and people based on the people, which is a difficult point." ”

Nie Junyu, chief expert of Huawei's smart city in China and chief expert of digital economy, pointed out that in the process of developing the digital economy, all regions in China usually face several "common dilemmas": one is how to integrate the regional digital economy into national strategies including "double circulation" and "city clusters"; the other is how to give full play to the location advantages of each region, "the digital economy gives many cities an opportunity to change lanes and overtake, which can forge longboard advantages and make up for shortcomings"; third, the current urban digitalization pays more attention to long-term effectiveness and integrity Therefore, higher requirements are put forward for the systematicness, complexity and logic of the overall solution of high-quality urban development.
How to smoothly expand the digital application from "bonsai" to "panorama", from a single point project to a complete smart city? Wu Zhiqiang believes that the biggest difficulty lies in the iteration of ideological concepts.
"We usually think that smart cities must have a complete central system, the top is the city brain, but in fact, the city has only one brain is not enough," Wu Zhiqiang said, now many single-point scenes have achieved intelligence, such as to be all connected to form a city wisdom network, only one database "brain" will make garbage information aggregation, power consumption increase dramatically, so the city should build a database group as a "crowd brain", synergy with each other, release integrated wisdom.

When talking about how digital technology can change cities in the future, Zhang Lijun, vice president of Tencent and general manager of East China Headquarters, believes that smart cities with digital as the base will change the traditional top-down management model, making individuals the main body of the city. "Smart cities will pay more attention to every bit of daily needs of every person, and the operation of the entire city is to think and develop around all aspects of citizens' lives, and everyone's interaction will contribute to urban development."
