Research on Coordination Mechanism of Urban Emergency Supply Chain Based on Quadrilateral Evolutionary Game under Emergencies
In recent years,emergencies have had an impact on the supply and price stability mechanism of urban living materials,resul-ting in shortage of materials and soaring prices,which exposes the poor operation of China's urban emergency supply chain and other problems.As important subjects of urban emergency supply chain,the behavioral strategies of government emergency departments,logis-tics platform enterprises,material guarantee enterprises and urban residents will directly affect the final effect of urban living materials emergency supply.Based on this,this paper uses a quadrilateral evolutionary game model to explore the evolutionary rules of the con-struction and operation of the urban emergency supply chain coordination mechanism in China.At the same time,numerical experiments are conducted to simulate and analyze the evolutionary stabilization strategy.The results show that the active participation of government emergency departments,the efficient operation of logistics platform enterprises,the move-in of material preservation enterprises,and the platform procurement by city residents are the key factors to achieve the evolutionary equilibrium of the system.Therefore,the govern-ment emergency department should use subsidies,penalties and other policy tools to guide multiple parties to participate in the construc-tion of synergistic mechanisms,so as to better cope with the impact of various emergencies and ensure"the smooth circulation,produc-tion and supply"of living materials.
