It is recommended to refer to the following papers. Understanding of urban management is a new trend in the process of urbanization and the in-depth development of urban management science, and it is also closely related to Scientific Outlook on Development. Urban management is a very advanced topic in the field of urban management at present. Under the guidance of Scientific Outlook on Development, strengthening Scientific Outlook on Development's urban management is a scientific summary of China's socialist construction and the practice of reform and opening up, and a major strategic thought put forward at a new starting point from the overall development of the cause of the party and the state in the new stage. How to strengthen urban operation and management under the guidance of Scientific Outlook on Development is of great and far-reaching significance to the urbanization process of China in transition. Strengthening urban operation management is not only the inevitable requirement of implementing Scientific Outlook on Development in urban management, but also the inevitable choice of China city at the crossroads of urbanization. I. Rediscovering Urban Operation With the rapid development of economy, urbanization has become an important topic in China today. For various reasons, urbanization was once alienated into the most "explicit" extended urban development road with reinforced concrete consumption as an important indicator, such as building construction projects, building bridges, building large squares and main roads. Even the scientific research of urban management focuses on urban planning and construction, while the research on urban operation is less. In urban management, the problem of attaching importance to planning and construction and neglecting operation management is becoming more and more prominent. There are many problems in urban management, such as putting the cart before the horse, asymmetric information, untimely management, fragmented management and overlapping functions, and various "urban diseases" have emerged. The purpose of urban development is not to build more tall buildings, square bridges and pile more reinforced concrete. The ultimate goal of urban development is to better serve the citizens through more effective urban operation. With the gradual entry of urban operation into the agenda of governments at all levels, the long-standing criticism of "emphasizing planning and construction but neglecting operational management" in urban management has begun to be improved. Beijing 2008 Olympic Games further pushed the long-neglected word "urban management" to the foreground. The Beijing Municipal Government organized and compiled the first "3C City Operation Outline" in China, and based on the outline, relying on information and communication technology, established the first city operation system information platform in China. This is also the first time that the International Olympic Committee has explicitly put forward the requirements for the host city of the Olympic Games to establish an urban operation center. In 2006 and 2007, Beijing "2008" environmental construction headquarters office also compiled and published "Analysis Report on Main Indicators of Urban Operation during the Olympic Games", which attracted wide attention from urban management practitioners and researchers. Second, re-examine urban management In order to better understand urban management, it is necessary to further examine the well-known urban management. Urban management refers to the decision-making, guidance, standardized coordination, service and business behavior around the operation and development of the city by taking the city as an open complex giant system, based on the basic information flow of the city, using a series of mechanisms such as decision-making, planning, organization, command, coordination and control, and adopting legal, economic, administrative and technical means, through the interaction of the government, market and society. Urban management in a broad sense refers to the management of all urban activities, including political, economic, social and municipal management. Narrow urban management usually refers to municipal management, that is, the management of urban infrastructure, public service facilities and social public affairs related to urban planning, construction and operation. The article Three-dimensional Structure of Urban Management from the Perspective of Complexity Science analyzes urban management from three dimensions: knowledge, time and logic, and points out that urban management is a management activity that runs through the whole process of urban planning, construction and operation with the goal of serving urban development and citizens' lives. From the perspective of specialty and industry, urban management includes the management of infrastructure, public utilities, transportation, gardens, environmental protection and other industries, as well as the application of knowledge in natural sciences, social sciences, humanities, geographical sciences and other professional disciplines. From the perspective of time, urban management includes three parts: pre-planning management, mid-term construction management and post-operation management, that is, the syllogism of urban planning, urban construction and urban operation management, which is well known to urban managers. Moreover, there is not a simple linear relationship among urban planning, urban construction and urban operation. There is not only an interactive feedback mechanism between these three stages, but also a constant dynamic change. It is the interaction of these three stages that promotes the development of the city. Three. Urban planning, urban construction and urban operation Urban planning is to plan the development of urban economic structure, spatial structure and social structure on the premise of development vision, scientific demonstration and expert decision-making. It plays an important role in guiding and standardizing urban construction, is the preliminary work of urban comprehensive management, and is the leader of urban management. The complex giant system of a city determines that urban planning is a complex continuous decision-making process that is adjusted, revised, improved and perfected for a long time with the operation and development of the city. Urban construction is based on planning, and transforming urban human settlements through construction projects is a basic and phased work that creates good conditions for urban management, and it is a special economic work with obvious process and periodicity. Urban operation refers to various matters related to maintaining the normal operation of the city, mainly including the management of urban public facilities and the services they carry. In the final analysis, urban planning and construction serve urban operation and citizens. After planning, construction and operation, urban facilities can function, provide services, create a good living environment for citizens and ensure their normal life.
