城市应急管理中灾害演化、结构嵌入与组织间合作关系形成研究OA

The driving mechanisms of collaborative relationships among emergency management agencies is a prominent research topic.However,existing literature lacks sufficient exploration of how disaster evolution and structural embeddedness influence the formation of inter-organizational collaboration.A multi-layer network model is employed in this research to simulate the disaster evolution and response process,proposing research hy-potheses on how disaster evolution and structural embeddedness impact the formation of these collaborations.Utilizing network configurations to characterize the formation mechanisms,an empirical analysis focused on Dis-trict A is conducted.By applying Multi-level Exponential Random Graph Models(MERGMs)to test the hypoth-eses,the intrinsic mechanisms are indicated through which disaster evolution and structural embeddedness drive inter-organizational collaboration.The findings indicate that sectors responding to the same emergency are more inclined to form collaborative relationships.Furthermore,agencies responsible for primary emergencies that trig-ger secondary disasters are more likely to collaborate with others.Simultaneously,two sectors sharing a common partner are more prone to collaborate with each other,and participating units demonstrate a preference for collab-orating with organizations situated at the central positions of the network.Scientific guidance is provided for local governments in this study to strengthen the emergency management systems.
