我国水权交易博弈定价决策机理

Price decision mechanics of Chinese water right trade in terms of game playing

结合水权交易双方的效用函数,基于博弈原理及方法分别建立了水权交易准市场阶段和水市场阶段的水权交易博弈定价模型,并对水市场定价模型的纳什均衡解进行了探讨;基于定价相关要素间关系的探讨,解析了准市场阶段和水市场阶段水权交易定价决策机理,结果认为水权交易双方存在利益冲突,并且准市场阶段水权交易定价相对较低,水市场阶段水权交易定价相对较高。

Based on the utility function, the pricing models of water right trade were set up in terms of playing game about near-water market stage and water market stage, the Nash equilibrium of formal water right trade market stage was discussed and the relevant relations about key element to market pricing model of water market stage were analyzed . Thus the pricing decision mechanics were obtained. It was found that there exists benefit conflict in water market, and the water right trade pricing in near-water market stage is comparatively low, and the water right trade pricing in water market stage is comparatively high.
