| In order to solve the problem of low participation rate of residents′ garbage classification, based on evolutionary game theory, this paper constructs a tripartite evolutionary game model with the participation of local governments, property companies and residents, analyzes the stability strategy and implementation conditions of evolution, and uses MATLAB software to simulate the evolutionary behavior of each game player under different parameter values. The research shows that supervision, regulation, classified release strategy is the most practical and stable strategy for the three parties, and its realization is affected by the behavior income, the cost of the three parties′ behavior and the reward and punishment mechanism. The change of the initial state of the three parties will not affect the stable convergence result, but the decision convergence process of the property company and residents will be subject to shocks; adjusting the parameters of the local government reward and punishment mechanism can change the evolution path of the property company and residents to the convergence result at the same time, and increase the convergence speed. |
