| Public health emergencies can easily cause large-scale property damage and personal health problems in a short period of time,resulting in a state of emergency in society.In order to build a better governance system and improve the governance capacity of public health emergencies,this paper analyzes the spatial and temporal distribution patterns of public health emergencies by using data related to public health emergencies in 31 provinces,autonomous regions and municipalities directly under the central government(excluding Hong Kong,Macao and Taiwan)from 2008 to 2021,and analyzes the spatial and temporal aggregation characteristics of public health emergencies by using geospatial analysis and spatial and temporal scanning statistics.Based on the theory of collaborative governance,a collaborative governance model was developed for public health emergencies at the temporal and spatial levels respectively.The findings of the study are as follows:(1)The overall temporal distribution of public health emergencies shows a decreasing trend year by year,and the prevention and control of emergencies in China has achieved certain results in recent years,but it is still necessary to focus on the normalized prevention and control of public health emergencies and encourage the public to actively participate in the prevention and control work to realize the prevention and control of public health emergencies in life;meanwhile,the spatial distribution of public health emergencies shows a high trend in the western region and a low trend in the eastern Meanwhile,the spatial distribution of public health emergencies is high in the western region and low in the eastern and central regions,and in general,the prevention and control of public health emergencies in China has been effective,but some provinces and cities in the western region of China still have crisis risks and still need to focus on them.(2)According to the results of spatial auto-correlation and spatial-temporal scan analysis,the spatial correlation of public health emergencies in each province in China between 2008 and 2021 shows a positive correlation,and there is a significant aggregation phenomenon in the spatial distribution.Meanwhile,provinces and cities in northern,northeastern,eastern and central China have been in low aggregation areas for a long time,while Xinjiang and Hainan,Guangdong and Guangxi have experienced high values of aggregation at different time periods.This phenomenon may be related to the natural conditions,economic level,medical capacity and the degree of popularization of prevention and treatment knowledge among the public in each province and city.(3)According to the different development cycles of public health emergencies and their nature,a stage-by-stage collaborative governance model for public health emergencies is proposed: a complete collaborative organizational structure and system should be built during the crisis outbreak period to guarantee the effectiveness of collaborative response;the crisis occurrence period should focus on grasping the direction of the situation and avoiding the spread of the event;the crisis decline period should review the event,summarize the experience,improve the emergency management system,and prevent The crisis recession period should be reviewed,experience should be summarized,and the emergency management system should be improved to prevent the recurrence of crisis.In addition,according to the spatial effects of public health emergencies,the "leading-participating" and "autonomous-joining" modes of collaborative governance are proposed respectively,taking into account the different characteristics of high-and low-incidence areas.In addition,based on the spatial effects of public health emergencies,the "leading-participating" and "autonomous-associating" governance models are proposed to improve the prevention and control capabilities of each region and to realize regionalized and coordinated common prevention and treatment of public health emergencies. |
