Abstract: The rapid development of urbanization has brought about increasingly prominent urban management issues. The concept of smart city provides a new idea for solving urban development problems and improving urban competitiveness. Since 2010, the local government has started to explore the smart city construction model spontaneously. Since then, under the guidance of the central ministries, pilot projects on smart city construction in various fields have been carried out, and further coordination and resource integration have been carried out from the national strategic level. Despite the good momentum of China’s smart city construction, it still faces problems such as insufficient strategic planning, widespread information island problems, serious technology orientation, huge construction funding gap, imperfect evaluation system and neglect of information security construction. The 13th Five-Year Plan outlines the establishment of a new type of smart city. Promoting the construction of a new smart city should strengthen overall planning, break the information island, adhere to the people-oriented construction goal, promote classification and promotion, actively coordinate the participation of social forces, strengthen technical and financial security, and build network information security system.
