Abstract
To reveal the interaction and influence mechanism between emergency rescue entities, and to explore and optimize a cooperation mechanism of emergency rescue entities, a tripartite evolutionary game model of emergency rescue cooperation based on government rescue teams, social emergency organizations, and government support institutions was constructed. The stability of each game subject’s strategy choice was explored. Simulation analysis was applied to investigate the influence mechanism of key parameters on the evolution of the game subject’s strategy combination. The research results show that government rescue teams, social emergency organizations, and government support institutions have consistent political demands and rescue targets in emergency rescue cooperation. The game subjects are driving forces for each other to choose positive strategies. The game evolution process of the emergency cooperation model shows a “mobilization-coordination” feature. At the same time, the emergency capital stock formed based on trust relationships, information matching, and institutional norms between game subjects can promote the evolution of the game system toward (1,1,1). In addition, for government organizations with limited emergency resources, the average allocation of emergency resources is not the optimal solution for emergency rescue efficiency. However, it is easier to achieve the overall target of emergency rescue cooperation by investing limited emergency resources in key variables that match the on-site situation. On this basis, combined with the practice of emergency rescues in emergencies, countermeasures and solutions are proposed to optimize the mechanism and improve the efficiency of emergency rescue cooperation.
Highlights
In recent years, with the superposition and coupling of various risk factors, emergencies have shown more obvious complex characteristics, such as intersections, derivatives, chains, and randomness
This study focuses on the horizontal cooperation between the government rescue team, the government support institution, and the social emergency organization, and the administrative constraints of the vertical directive relationship are incorporated into the parametric hypothesis
This study revealed the formation mechanism and path of evolutionarily stable strategies of the government rescue team, the social emergency organization, and the government support institution
Summary
With the superposition and coupling of various risk factors, emergencies have shown more obvious complex characteristics, such as intersections, derivatives, chains, and randomness. It has been difficult for the previous management mode of relying on a single government department to effectively manage all kinds of emergencies [1,2]. In the practice of emergency management, the Chinese government has gradually formed institutional and voluntary emergency cooperation mechanisms [3]. Further exploring cross-organization, the cross-sector mode, and its characteristics formed between emergency organizations has become an important topic in the field of emergency management research [4,5,6]. As an important component of emergency management, an emergency rescue is the most direct link to protect the safety of people’s lives and property, reduce the losses of emergencies, and prevent the occurrence of secondary disasters, which are remarkable characteristics of an emergency cooperation mechanism
