The traditional urban management model is sloppy, with unclear responsibilities and professional division of labor; the government takes charge of everything and lacks effective supervision; and the manual mode of operation is outdated and ineffective, which is unable to meet the requirements of modern urban management. At the beginning of the research and construction project of grid-based urban management and operation service platform, China's urbanization process was entering a rapid development stage, and the urban management could not cope with the huge increase in the load of the rapid expansion of urban areas and population, which became a bottleneck for the sustainable development of the city. There is an urgent need to rely on digital city information technology, in response to the above complex system requirements, reengineering urban management model and digital processes, to create advanced and efficient information service platform and technical equipment, to strengthen the complexity of urban operation management and multi-party collaborative **** governance capabilities, set the great, into the wisdom, and urgently need to build a comprehensive and integrated information system model capable of enhancing the level of urban management and operation services, refinement, intellectualization, socialization.

The "City of the City of the City of the City of the City" is a comprehensive and integrated information system model.

From Digital City Management to Intelligent City Management: System Modeling and Realization Path compares the evolution of traditional city management, digital city management and intelligent city management. Relying on modern information technology to cope with the challenges of complexity of urban management, it is necessary to first solve the problem of holistic and critical digital expression of the complex system of real city operation, and to solve a series of key technological problems in the construction of the grid-based urban management and operation service platform, so as to realize the standardization and digitization of urban management. Digital city is the foundation of digital city management, which comprehensively uses GIS, RS, GPS, telemetry, network, multimedia and virtual simulation and other technologies to realize automatic collection of information, dynamic monitoring and management and auxiliary decision-making services for urban infrastructure and functional mechanisms. Digital city management is also the foundation of intelligent city management construction.

Digital city management (referred to as: digital city management) through modern digital information technology, based on digital maps and unit grid division, integration of basic geography, geographic coding, municipal and community service components, events of a variety of data resources, urban components, events, management subjects, management objects and management processes of standardization and digitalization. With the development of social and economic environment, ideology and information technology, urban management is also constantly exploring, through the reengineering of management process and the application of new technology, promoting urban management innovation, further improving the level of refinement, intelligence and socialization of urban management on the basis of all-around digitalization of urban management of people, places, objects, things, organizations and situations, realizing the transformation from e-government to e-public service, and from urban management to urban governance. The transformation from e-government to e-public affairs and from urban management to urban governance is being realized.

Wisdom city management is a new development of digital city management and a new stage of information city management under the background of innovation 2.0 and smart city development. Smart city management is a new model of city management under the environment of innovation 2.0 of knowledge society supported by new generation of information technology, realizing comprehensive and thorough perception, broadband ubiquitous interconnection, intelligent integration and application supported by new generation of information technology, and promoting people-oriented sustainable innovation characterized by user innovation, open innovation, mass innovation and collaborative innovation.

From Digital City Management to Intelligent City Management is a series of articles focusing on the development trend of the intelligent evolution of digital city management, from management innovation to platform implementation, key technologies, system modeling, and the path of realization for an all-round interpretation.
