摘要
当前我国水资源存在人均占有量低、水资源时空分布不均的问题,促使了水权在不同地区、不同行业之间交易。然而,水资源的效用性使得需水方在获取效益的同时,不得不考虑水资源获取的成本,即水权交易价格。本文首先从水权的边际效用、边际成本理论切入,对水权交易价格的制定进行经济学解释,接下来分析了农业水价综合改革中农业用水精准补贴对水权交易基础价格的影响。然后,以甘肃省水权交易价格形成为例进行了实证研究。最后,在此基础上提出农业节水的政策性建议,为落实农业水价综合改革,建立水权定价机制提供理论支持。
Water resources per capita are low and water resources allocation is uneven, promoting the trade of water rights in different regions and industries. The utility of water resources makes it necessary for the demand side to take into account the cost of water resources acquisition, which is the price of water rights transaction. Firstly, based on the two main theories of marginal utility and marginal cost ,the study explains the pricing of water right transaction economically , then it analyzes the impact of the precise subsidy of agricultural water use on the basic price of water right trade in the comprehensive reform of agricultural water price. Then, taking the price of water rights trading in Gansu Province as an example ,an empirical study. Finally, on this ba- sis, it puts forward the policy recommendations of agricultural water-saving to provide protection for implementation of comprehensive reform of agricultural water pricing and the establishment of water pricing mechanism.
