Study on the supply of urban public service facilities and the path of cracking based on public health emergencies ——Take Wuhan as an Example

The public service system in public health emergencies indicates the problems of hierarchical mismatch and conducted downward Invalidation in response to explosive demand shocks. This article clarified the fragility of the public service system in response to emergencies, constructed a hierarchical facility supply system of "upper control, middle flexibility, lower feedback” as the core, "evaluation, supply, and management " from the whole process of the facility supply ,emphasizes the framework of "full-link vulnerability assessment, full-coverage hierarchical supply, and full-cycle operation management", based on the overlay analysis of the spatio-temporal dynamics of the magor epidemic's initiation, outbreak, spread ,control and the type, level , spatial distribution characteristics of public service facility system. This article explored the transformation of the supply path of public service facilities under public health emergencies combining with Wuhan to conduct empirical verification.The assessment link should focus on the fragility of public service facilities, and construct a public service system and facility assessment system to ensure the effectiveness of space supply; the supply link should focus on community residents’ needs as the main body, clarify the needs and spatial layout, and ensure the fairness of the supply of public service facilities; The operation and management link should strengthen the construction of the community planner system, establish an operation management mechanism that pays equal attention to supervision and communication between the system and life subjects, and improve the efficiency of matching the supply and demand of community facilities.Further research found that the factors includes the failure in response to community prevention and control positions, imbalances in the configuration of the public service system, significant gaps in public service levels, and lagging online emergency supply are the major causes of the failure of the temporal and spatial correlation between public health emergencies and the supply of public service facilities. Based on these issues, this article proposed a solution to the supply of urban public service facilities to respond to explosive demand shocks: (1) differentiated supply combining centralized and decentralized supply; (2) strengthening service entities to focus on residents' demand orientation; (3) multi-sectoral coordination Implementation process management; (4) planning the operation guidance mechanism of in-depth intervention. Finally, based on these cracking paths a corresponding spatio-temporal emergency prevention and control network strategy is proposed to alleviate the supply crisis of urban public service facilities caused by the strong negative effects of public health emergencies.
