水资源定价方法与实践研究Ⅱ:海河流域水价探析

以水资源价值内涵分析为基础,对水资源定价理论与实践进行了研究,提出水资源供给价格应包括水资源费、供给成本和水环境补偿税;水资源需求价格通过产业用水经济价值确定;供给价格和需求价格共同作用决定水资源市场价格;在非市场化体系中通过影子价格评价水资源价值;依据水价构成及平衡关系,确定了水资源费的定量评价方法;利用投入产出分析技术构建简化的CGE模型,结合多种评价方法对水资源影子价格、水经济价值、水资源费、供给成本和水环境补偿税分别进行了定量评价,为水价形成机制提供了理论基础,为水资源定价标准提供了方法和实践支撑。研究成果可对实行最严格的水资源管理制度、完善水价定价机制、促进利用价格杠杆调控水资源分配提供参考。

Study on water pricing method and practice II. Discussion on water price of the Haihe Basin

Based on the connotation analysis of the value of water resources, the theory and practice study for price of water resources were developed. The supply price of water resources should be composed of water resources fee, cost of supply and environment compensation fee for water. Demand price of water resources should be determined by economic value of water resources. Market price of water resources should be determined by provide price and demand price, and it could be evaluated by shadow price in non-marketization system. According to the equilibrium relation of water price, quantitative evaluation method for water resources fee was put forward. Based on the simplified CGE model and related methods, some key factors were quantitatively evaluated, such as shadow price, economic value, water resources fee, supply cost and environment compensation fee for water. The output of this study will provide theory support for pricing mechanism of water resources and practice support for pricing standard. The achievements are significant for practicing most strict water resources management, setting up price mechanism of water resources, allocating water resources by price lever.
