基于水市场的水权水资源税博弈分析

A Game Playing Analysis of Water Rights and Water Resources Taxes Based on Water Markets

我国水资源紧缺日益严重,这就要求我们对有限的水资源量进行合理配置。以博弈论为基本理论框架,建立序贯博弈模型,在水市场存在的条件下对初始水权和水资源税进行博弈分析,运用倒推法求解子博弈精炼纳什均衡,从而得出如何分配初始水权分配和水资源税征收数额,实现对流域水资源的优化配置。同时对建模思路和解决方法进行阐述,并给出算例予以解释。

The scarcity of water in China is increasingly serious every day, which requires us to allocate our limited water in a more reasonable way. Based on the game theory, under the condition of water markets, this research tries to establish a model of sequen- tial games, which gives game playing analysis to the initial water right and water resource taxes, and then calculates the model by means of backward induction to the result of subgame perfect nash equilibrium,whose conclution is how to allocate the initial water right and makes out the quantity of the water resources taxes collection. Finally, a case study is used to show the construction of the model and its solution, which gives an optimal strategy for water allocation.
