| 摘 要： | 水权交易是提高水资源配置效率和利用效率的有效途径，但交易过程中第三方回流效应的存在是对水权市场的严峻挑战。如何解决这种第三方效应问题是完善水市场、提高水资源使用效率的关键。根据设计的张掖市甘临高地区可能实现的水权交易情景模式，测算了实际水权交易运行中回流效应的大小；设计一种水权交易比率制度，并使用MATLAB仿真模拟平台进行一般水权交易和水权交易比率制度的模拟。结果表明：农业部门内部水权交易回流效应主要受到交易水量规模的影响，当取最大可交易水量30%、50%和80%时，盈科灌区-骆驼城灌区水权交易引起鸭暖灌区的第三方回流效应分别为-5.97×106 m3、-9.95×106 m3和-1.59×1011 m3，市场规模越大，第三方回流效应越大；水权交易比率制度下的用户用水总效益为1.09×109元，比水权交易的初始分配状态用水效益7.51×108元提高3.41×108元。对比表明水权交易比率制度可以在避免第三方回流效应的同时可以提高水市场的用水效益。

| Abstract: | Water rights transaction is one of effective ways to improve the efficiency of water allocation and utilization. However, there is a severe challenge to the water right market due to the effect of return flows of third party. How to solve the problem of third party effect is the key to a perfect water market and to a higher efficiency of water use. In this paper, the scenarios of water transaction were designed, and the real effect of water rights transaction was estimated in Gan-Lin-Gao district of Zhangye Prefecture. Then a trading-ratio system was designed for water market to simulate the water right exchange rate and general water right trade with MATLAB simulation platform. Research results indicate that the effect of return flow during water right transaction within the agricultural sector is mainly affected by water amount. Taking the maximum tradable water amount as 30%, 50% and 80%, the water rights transaction between Yin'ke and Luotuocheng irrigation districts will result in return flows of third party of -5.97×106 m3, -9.95×106 m3 and -1.59×1011 m3 in Yanuan irrigation district, respectively; the greater the size of the market, the larger the return flows of third party. The total benefit of users under the water rights transaction ratio system is 1.09 billion RMB, which has increased by 0.34 billion RMB as compared with the initial state of allocation. The comparison shows that the water rights transaction ratio system can raise the efficiency of the water market and avoid the effect of return flows of third party simultaneously. |
