Abstract:

To optimize the emergency material reserve system and enhance the effectiveness of emergency response, a four-party evolutionary game model for collaborative emergency material reserve was constructed, incorporating the government, the emergency industry, the media, and the public, with public participation taken into consideration. The asymptotically stable points of the system and their conditional constraints were determined, and the evolutionary stability strategies were analyzed through numerical simulation. The results show that multiple evolutionary stability strategies exist in the system, which can be mapped to potential scenarios of multi-agent collaborative reserve. It is concluded that the government should guide the public to reserve emergency materials reasonably based on regional risk characteristics. Against the backdrop of frequent emergencies, the government should draw on the supply guarantee model of Shimian County in Ya'an, Sichuan, and the flood and typhoon prevention experience of Zhejiang Province, and enhance public acceptance and awareness of independent reserve through media science publicity and policy guidance. In the context of routine risk response, the government should refer to the experience of Weifang in Shandong Province in establishing an emergency industry alliance, give full play to the market role of the emergency industry, and promote active reserve behavior among the public through media advertising and experiential publicity.
