摘要
水权交易是实现水资源有效配置的手段,而交易水价的估算又是进行水权交易的重要依据。选定反映水资源稀缺程度和经济发展水平的水资源影子价格作为水资源价值量化手段,提出在水权交易中的水资源影子价格递减效应、递增效应等概念,分析了水权交易中水资源影子价格对交易水量的递减(买方)、递增(卖方)效应,以及对时间的递增效应等对交易水价的影响,并据此推导了水权交易的水价估算方法以及最佳交易水量的确定方法。通过中国甘肃省与宁夏回族自治区之间进行的水权交易实例计算,阐述了具体实现方法。
Water right trading is an effectual instrument for allocating water resources, and estimates of the water price are the primary factor affecting the trading. The shadow price of water resources reflects the scarcity of water and the degree of economic development. Increases or decreases in the shadow price will affect the water price in water right trading. An analytical method was developed to estimate the effects of increases or decreases on the water price and the optimum amount of bargaining water in water right trading. Water trading between Gansu province and Ningxia Hui Autonomous Region is used to illustrate how the method can be implemented.
