多主体参与下应急物资储备的三方演化博弈研究

Research on the Tripartite Evolution Game of Emergency Material Reserves under Multi-agent Participation

针对医用应急物资需求的特点,从政府监管、公众监督和医药企业储备三方联动视角研究突发公共事件中的医用应急物资储备策略,构建应急物资储备三方演化博弈模型,分析演化博弈系统中各均衡点及其稳定性条件,探讨各个参与主体的策略选择的动态演化过程,并对部分参数进行数值仿真。结果表明:政府监管和公众监督存在互补关系,加入公众监督,可以更好地约束企业的行为,且适当的惩罚和奖励可以提高医药企业储备和公众监督行为的意愿。

According to the characteristics of medical emergency materials demand,the strategy of medical emergency materials reserve in public emergencies was studied from the perspective of government supervision,public supervision and pharmaceutical enterprise reserve.This paper built a tripartite evolutionary game model for emergency materials reserve,analyzed the equilibrium points and their stability conditions in the evolutionary game system,discussed the dynamic evolution process of the strategy selection of each participant,and carried out numerical simulation of some parameters.The results show that there is a complementary relationship between government supervision and public supervision,adding public supervision can better constrain the behavior of enterprises,and appropriate punishment and reward can improve the willingness of pharmaceutical enterprises to reserve and public supervision behavior.
