The process of urbanization is accompanied by complex and changeable risks, and it is urgent to strengthen the response and explore the effective mechanism and path of urban risk management modernization. On the basis of the traditional research based on the perspective of static events, more attention should be paid to the changes of risk content from the perspectives of "technology", "people" and "events", focusing on the characteristics of complex association, overall emergence, diffusion amplification, multiple superposition and uncertainty of urban risks, and constructing a front-loaded risk governance framework. It is necessary to give full play to the role of digital technology in empowering urban governance, strengthen digital risk research and judgment, improve digital risk prevention and control, improve intelligent decision-making and risk assessment, build an intelligent risk prevention and control coordination mechanism, improve digital risk supervision, and create a full-cycle urban risk governance system. Looking forward to the future, it is necessary to build a "warm" high-quality urban governance system, promote risk governance with a systematic concept, innovate the risk governance system, promote people-centered refined governance, and form a new pattern of risk governance with multiple co-governance.
