| 摘 要： | 运用经济学理论分析了水价与水资源需求的关系；以实例表明提高农业水价对农业节水的影响；以黄河流域为例，计算农业需水价格弹性，结果表明，当黄河流域农业灌溉水价提高10%，农业亩均用水量将下降5.71～7.41%，将现行水价调整到成本水价，在灌溉面积不变的条件下，可减少用水63.05亿m3，下降22.8%。

| Abstract: | The relationship between water price and water resources demand is analyzed by using economic theory, and case study is conducted to indicate the impact of raising agricultural water prices on agricultural water saving; agricultural water use price elasticity is calculate with the background of the Yellow River Basin. The results show that the agricultural water use can decrease 5.71 % ~ 7.41 % if the agricultural water price increases 10% in the Yellow River Basin, and 22.8 % of water (6.305 billion) can be saved if the current price reaches the cost price in the same irrigation area. |

| Keywords: | agricultural water price water saving demand function demand price elasticity coefficient water price reform |
