Game Analysis of Investment Subjects in Transportation Facilities Project under PPP Background

针对交通设施PPP项目中投资主体是否投入,以及投资多少的问题,该文通过轮流出价对政府和社会资本进行分析,采用逆向归纳法求解子博弈精炼纳什均衡,从而得到最优合作模型。所得结果不仅为政府和社会资本提供了对PPP项目的投资决策方法,而且为政府管理社会资本准入提供了理论依据。

In the PPP project of transportation facilities,whether the investment subject is invested and how much investment needs to be solved,this paper analyzes the government and social capital through the rotation of bidding,and uses the inverse induction method to solve the subgame perfect Nash equilibrium.Thereby the optimal cooperation model is obtained.The results not only provide government and social capital with investment decision-making methods for PPP projects,but also provide a theoretical basis for the government to manage social capital access.
