基于博弈论的南四湖流域生态补偿理论分析

采用博弈论的分析方法寻找南四湖流域生态补偿主客体的纳什均衡。在静态博弈模型和动态博弈模型得出两个截然不同的均衡：静态博弈的均衡是（不保护,不补偿）,动态博弈的均衡是（保护,补偿）。在静态博弈中进行激励设计,提高补偿客体保护水资源的积极性,实现帕累托最优,应该立法,制定严格的惩罚标准;动态分析是建立在完全信息的基础上,由此要求政府建立良好的信誉,才能保证均衡的长久,从而达到保护南四湖流域生态环境的目的。

The Theoretical Analysis on Ecological Compensation based on the Game Theory in Nansi Lake Basin

This paper uses game theory to explore the Nash equilibrium for the subject and object sides of ecological compensation of Nansi Lake basin.There are two different equilibriums between static game model and dynamic game model： the equilibrium of static game is（no protection,no compensation）,the equilibrium of dynamic game is（protection,compensation）.In the static game,the incentives in order to improve the object＇s motivation to protectwater resources and to achieve the Pareto optimal,related legislations are suggested to set up,which makes strict punishment standard,in order to achieve an expected equilibrium.The dynamic analysis is built on the basis of complete information,which requests the government to establish a good reputation in order to ensure a long-term equilibrium,so as to protect the ecological environment of Nansi Lake basin.
