摘要
河北省衡水市桃城区长期靠超采地下水来保证社会经济发展,长期的地下水超采使桃城区已成为冀枣衡地下深层淡水沉降漏斗区的中心。在如此严峻形势下,该区经过不断探索和实践,于2005年8月首创“一提一补”节水制度。本文利用河北省衡水市桃城区332户农户调研数据,运用倍差法模型定量分析桃城区农业水价改革“一提一补”实施后农户灌溉用水量的变化。研究结果表明,虽然政策对玉米灌溉用水量的影响并不显著,但在小麦种植上,试点村农户比非试点村农户的灌溉用水量显著减少了20%以上,可见“一提一补”水价改革有利于缓解华北平原的地下水超采形势。
This essay,using the rural investigation statistics of 332 households in Taocheng District,Hebei Province,established a DID model to analyze the change of households’ irrigation groundwater consumption after the experimental implementation of the "Collect then Refund"( Yi Ti Yi Bu) Water-Pricing Mechanism.The results show that the implementation of this mechanism has a remarkable water-saving effect and a net significant effect on reducing wheat irrigation groundwater consumption,but it does not have a net significant effect on corn irrigation groundwater consumption.
