Urban public security governance is an important part of the modernization of national governance system and governance capacity. In recent years，Shanghai has proposed the goal of “building a safe and resilient city”，comprehensively promoted the construction of “one network unified management” system for urban operation，taken the urban operation platform system and technical support system as the starting point，strengthened the value orientation of “application is the most important and effective is the king”，focused on “observation”，“management” and “prevention” around “efficient disposal of one thing”，and realized “one screen views the whole area and one network management of the whole city”. By strengthening top-level design and policy formulation，improving the urban operation and management system，process and mechanism，and adhering to the principle of closed-loop management in the whole process，Shanghai not only pays attention to the innovative application of a new round of information technology，but also constantly explores new super large-scale urban governance models，improves urban emergency management system and mechanism，and promotes the upgrading and evolution of urban governance.
