中文摘要：
利用价格杠杆提高农业部门的灌溉用水效率意义重大，但同时也可能对农业种植收入造成负面影响。本文通过建立纳入生产函数的农户多目标决策模型，分析黄河上游农业水价对作物用水及种植收入的影响。研究结果表明，随着水价的上涨，用水量对水价将先后经历无弹性、敏感弹性、最后又恢复低弹性的过程。水价提高将使种植收入持续下降。水价政策与适当的定额补贴政策双管齐下将达到既节约用水又兼顾农户种植收益的双赢结果。
英文摘要：
Water pricing is one of the essential policies to improve efficiency of water used in irrigation, but there are also concerns on its impact on farmers＇ income. This paper analyzes the impacts of water pricing policy, based on a novel multi-objective decision system. The results show that as water price increases, the absolute values of water demand elasticity increase from zero to a certain high level and then fallthereafter. The income from crop production would fall with water price. A decoupled compensation mechanism is highly needed to reach a win-win situation for both water conservation and farmers＇ welfare.
