提补水价对华北地下水超采区农户生计的影响研究

An Analysis of “Collection and then Refund” Water-Pricing Mechanism's Effect on Farmers' Livelihood in Groundwater Overexploitation Areas

运用DID模型,从农户生计的角度对河北省衡水市桃城区"一提一补"水价政策进行绩效评估,主要对当地水价改革试点村和非试点村农户作物产量和收入进行二重差分分析,结果表明:"一提一补"制度的实施不会对作物产量和农户收入产生负面影响,甚至会提高作物产量,故推行该制度对实现华北地下水超采区"节水保粮增收"具有重大现实意义。

This paper is an attempt to evaluate ＂Collect and then Refund＂ water-pricing mechanism by analyzing the policy＇s effect on farmers livelihood, by using difference-in-difference model. The results show that the implementation of this mechanism will not decrease crop pro- duction and farmers＂ income, and will even enhance crop production. So it is of great significance to pursue this mechanism in groundwater overexploitation areas.
