交通BOT项目投资的对策分析

GAME ANALYSIS ON THE INVESTMENT OF TRANSPORTATION BOT PROJECT

为了研究交通 BOT项目中政府的最优战略和私人投资者的最优战略之间的关系 ,建立了一个交通BOT项目的投资模型 ,并且采用对策论分析了该模型 ,分别为它们提出了最优战略 .在已经建立好模型后 ,证明了三个研究 Nash均衡解的存在性定理 ,并且给出了解的性质 .证明了政府和私人投资者的利益在特许权期上是一致的 ,换句话说 ,特许权期越长 ,它们的效用越高 ;特许权期越长或通行费越高 ,最优容量越大 ;容量越大 ,最优通行费越高 .

This paper set up an investment model of transportation BOT project to study the interrelations between the optimal strategies of government and the optimal strategy of private investor in transportation BOT project and analyzed the model by employing game theory, bringing forward optimal strategies for them, respectively. After it had set up the model, it showed the three theorems that study the existence of Nash-solutions and gave the natures of solutions. It showed that their profits are coincident in the concession term, in other words, the longer is the concession term, the higher their payoffs. The longer is the concession term or the higher is toll, the larger the optimal capacity. The larger is capacity, the higher the optimal toll.
