基于纳什谈判解的水权交易模型研究——以济宁为例

Research on Water Right Transaction Model Based on Nash Bargaining Solution——Taking Jining as an Example

根据我国水权交易市场处于准市场阶段的实际情况,在总结国内外水权交易管理理论与实践的基础上,以合作博弈论为理论基础,建立了符合我国准市场条件下的水权交易模型,分析了水权交易双方的出价策略和收益函数,并利用纳什积计算得出模型的纳什谈判解,即水权交易双方都可接受的水权价格。以济宁市为例,构建工农业水权交易的合作博弈的模型,计算得该模型的纳什谈判解;并对比不同的交易方案,分析得出工农业水权交易模型的纳什均衡点。结果表明,工农业之间进行水权交易可以带来显著的经济效益,模型对工农业水权交易的决策有良好的指导意义。

This paper establishes the water rights trading mode based on the cooperative game theory l. The bidding strategies and the income functions of the water rights trading parties are analyzed and the Nash bargaining solution of the model is obtained. By taking the City of Jining as an example,a cooperative game model of water rights trading between agriculture and industry is established,and the Nash bargaining solution and Nash equilibrium point of the model are obtained. The results show that the water rights trading between industry and agriculture can bring about significant economic benefits,and the water rights transaction model has an important guiding significance for decision-making.
