围绕探讨安全生产市场化服务供求的演化规律,在分析安全生产市场化服务存在问题的基础上,借助演化经济学方法,构建了企业与服务机构行为交往的支付矩阵;通过对交往过程的演化模型分析,揭示了个体策略选择对群体行为的影响;分析了系统演化的6种情形,针对混合策略均衡情形,利用Matlab软件数值仿真演示了两群体不同初始比例和不同参数变化对系统演化结果的影响;并提出了避免陷入"不良"锁定,引导系统向着预期方向演进的建议。
To find out the evaluation law of supply and demand of production safety marketing services,the problems of production safety marketing services are analyzed.The payment matrix of MSEs and service agencies is built by using the method of evaluation economics.By analyzing the evolution model of association between MSEs and service agencies,the effect of individual decision-making on group behavior is probed.Six different scenarios of the system are analyzed,and the effects of different initial condition and different decision parameters on evolution result are discovered by numerical simulation by Matlab software under mixed strategies equilibrium.Suggestions are put forward on how to avoid falling into the bad locked type to go toward the expected direction.
