In order to facilitate the rapid formation of a disaster and accident trans-regional collaborative governance community in response to major emergencies，this study employed fsQCA. It investigated fourteen cases by selecting seven conditional variables across three dimensions: Incentives，mechanisms，and guarantees. These variables included value consensus，existential threats，administrative mobilization，collaborative linkage mechanisms，interest equilibrium mechanisms，legal guarantees，and digital intelligence technologies. The study explored the core influencing factors and the complex causal relationships in the formation of the disaster and accident trans-regional collaborative governance community. Configurational analysis identified three patterns of community formation: party-government-led，value-driven，and crisis-triggered，with each pattern corresponding to typical cases in the case database. The findings reveal that collaborative linkage mechanisms are a necessary condition for the formation of emergency management communities，while the other six variables cannot individually serve as necessary conditions. Optimizing the functionality of collaborative linkage mechanisms can effectively promote the development of trans-regional emergency management communities.
