说明：  选取政府、配送企业、用户为城市货运过程中的博弈参与主体，为了分析在城市货运政策推广过程中影响各参与主体策略选择的因素，提出了构建政府、配送企业、用户三者之间的演化博弈模型。在分析博弈三方不同策略的成本和收益基础上，采用系统动力学方法对模型进行仿真分析。
(The government, distribution enterprises and users are selected as the participants of the game in the process of urban freight transportation. In order to analyze the factors affecting the participants'strategy selection in the process of promoting the urban freight transport policy, an evolutionary game model among the government, distribution enterprises and users is proposed. Based on the analysis of the cost and benefit of three different strategies, the system dynamics method is used to simulate and analyze the model. The results show that the government, distribution enterprises and users all attach importance to the revenue of the strategy when choosing the strategy;)
