"To promote the modernization of national governance system and capacity, we must do a good job in modernizing urban governance system and capacity." The only way which must be passed by City Secretary Xi Jinping, general secretary of Zhejiang, was to make the city smarter and smarter, which is the only way to promote the modernization of urban governance system and governance capacity.

Experts interviewed by China Economic Times said that smart cities should promote the modernization of urban governance system and governance capacity; the governance experience in anti epidemic work should be transformed into a long-term mechanism to build a modern social governance system that is "easy to use in peacetime and effective in wartime".

"Smart city governance refers to a diversified cooperative governance model based on urban grid space governance technology, with Internet of things technology as the backbone and people as the center." Ye Yumin, a professor at the school of public management of Renmin University of China, told China economic times that smart cities promote the modernization of urban governance system and governance capacity in three aspects.

First, establish a modern urban governance technology system. Through modern cutting-edge technologies such as big data, cloud computing, blockchain, artificial intelligence and digital twin, we can systematically and efficiently collect, count and sort out economic, social and spatial information in urban governance, achieve information symmetry, reduce information search cost and transaction cost of urban governance, improve urban governance efficiency, and enable urban governance to be managed by "gray box" The trend of transparent governance, from fuzzy management to fine governance, provides technological possibility for the city from traditional management to modern governance, and greatly improves the modernization process of governance capacity.

The second is to establish a modern urban governance system based on transparent and symmetrical information system. The smart city has the conditions to construct the system and governance structure of governance decision-making, implementation and supervision, which are balanced by the division of labor, to solve the paradox of "low cost and high efficiency" in the internal operation of the Department and "high cost and low efficiency" in the overall operation of the city in the process of traditional urban management in China, and to effectively promote the long-term existence of "urban management disease" (superficial, beneficial and indifferent) in China Modernization of urban governance system.

Third, the governance system is the system, and the governance ability is the ability to use the system to govern the city. At first, smart city constructs a modern urban governance capability. At the same time, the full use of information technology forces the reform and innovation of urban governance system and governance concept, and promotes the formation of urban modernization system. Therefore, smart city can promote the modernization process of urban governance system and governance capability at the same time.

Ye Yumin said that "seven modernizations" can be used to reflect the characteristics of smart city governance: to reflect the socialization of problems, to determine the standardization of problems, to implement the process of responsibility, to open the supervision process, to analyze problems digitally, to solve problems by law, and to authoritative organizations.

Wang Xiongjun, deputy director and researcher of China Knowledge Center for international development, said in an interview with China economic times that the following three aspects should be focused on in order to transform the governance experience in anti epidemic work into a long-term mechanism and build a modern social governance system that is "easy to use in peacetime and effective in wartime".

First, adhere to and consolidate the huge institutional advantages in the process of epidemic prevention and control. China's epidemic prevention and control has achieved remarkable results in a short period of time, thanks to the significant institutional advantages of the national governance system. For example, adhering to the national unity, mobilizing the enthusiasm of all parties, and concentrating on the institutional advantages of major events, the command and deployment of epidemic prevention and control realized the systematization, integrity and coordination, and formed the people's war, the general war and the Resistance War of epidemic prevention and control. We should fully respect experts, formulate scientific and effective prevention and control policies, and do a good job in knowledge popularization, behavior guidance, emotional comfort, etc. of the public. The advantages of these systems in the process of epidemic prevention and control should be systemized and summarized in time to make these systems more mature and perfect.

Second, the system defects and deficiencies exposed in the process of reform and improvement of epidemic prevention and control. The construction of the national governance system should be based on a long-term perspective, and be amended and improved in time in response to the institutional weaknesses, loopholes and weaknesses in the process of epidemic prevention and control. In view of these problems, we should not only correct and deal with them in time, but also take a long-term stand, and prevent similar problems from happening again by reforming and improving the corresponding system.

The third is to strengthen the new technology support and application practice in social governance. With the rapid development of information technology, there are many new tools for social governance. Such as health code, cloud platform, etc., have played an important role in the epidemic prevention and control. The construction of national governance system should focus on the future, attach great importance to the supporting role of new technology in modern governance system and governance capacity, strengthen the construction of basic system and technical reserve in peacetime, and do well in emergency plan and drill.
