The traditional urban management mode is extensive, the responsibilities are unclear, the industry is specialized, the government does everything, the effective supervision is lacking, the manual operation means are backward, and the efficiency is low, which can not meet the requirements of modern urban management. At the beginning of the research and construction project of grid urban management and operation service platform, China's urbanization process is entering a stage of rapid development, and urban management has been completely unable to cope with the huge increase in the load brought about by the rapid expansion of urban area and population, which has become the bottleneck of urban sustainable development. It is urgent to rely on the information technology of digital cities, rebuild urban management mode and digital process, build advanced and efficient information service platform and technical equipment, strengthen urban operation complexity management and multi-party cooperation ability, and integrate wisdom. It is urgent to build a comprehensive integrated information system model that can improve the refined, intelligent and socialized level of urban management and operation services.

From digital urban management to smart urban management: system modeling and realization path comparison of the evolution process of traditional urban management, digital urban management and smart urban management. Relying on modern information technology to deal with the complex challenges of urban management, we must first solve the problems of the integrity and key digital expression of the complex system of real urban operation, solve a series of key technical problems in the construction of grid urban management and operation service platform, and realize the standardization and digitalization of urban management. Digital city is the foundation of digital city management. It uses GIS, RS, GPS, telemetry, network, multimedia and virtual simulation technology to realize automatic information collection, dynamic monitoring management and decision-making service for urban infrastructure and functional mechanism. Digital urban management is also the foundation of smart urban management construction.

Digital city management (referred to as digital city management for short) integrates various data resources of basic geography, geocoding, municipal and community service components and events through modern digital information technology, based on digital map and cell grid division, and realizes the standardization and digitization of management subjects, management objects and management processes of urban components and events. With the development of social and economic environment, ideology and information technology, urban management is constantly being explored. Promote urban management innovation through management process reengineering and the application of new technologies. On the basis of all-round digitalization of people, places, things, organizations and feelings in urban management, we will further improve the level of refinement, intelligence and socialization of urban management and realize the transformation from e-government to e-government and from urban management to urban governance.

Smart 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 urban management is a new mode of urban management under the environment of knowledge society innovation 2.0 supported by a new generation of information technology. Through the support of a new generation of information technology, we will realize comprehensive and thorough perception, ubiquitous broadband interconnection and intelligent integrated application, and promote people-oriented sustainable innovation characterized by user innovation, open innovation, mass innovation and collaborative innovation.

From digital urban management to smart urban management, a series of articles focus on the development trend of intelligent evolution of digital urban management, from management innovation to platform implementation, key technologies, system modeling and implementation paths. Reference: from digital urban management to smart urban management: platform implementation and key technologies; From digital urban management to smart urban management: system modeling and realization path: from digital urban management to smart urban management: urban management innovation from the perspective of innovation 2.0.
