黄河流域水权交易机制的多维政策效应研究OA

To support the high-quality development of the Yellow River Basin,this study evaluated the green,coordination and efficiency in-dices of high-efficiency water resource utilization in the basin based on a mixed weighting approach.Using a Difference-in-Differences(DID)model,this study examined the policy shock,multidimensional impacts and policy integration effects following the establishment of the na-tional and Yellow River Basin water rights trading platforms in 2016.The results indicated that:Water rights trading significantly improved the green index of high-efficiency water resource utilization in the Yellow River Basin,with a specific increase of 6.540;The coordination and efficiency indices increased by 1.243 and 1.972,respectively.From the perspective of policy integration,the integration of water-saving poli-cies,afforestation policies and water rights trading policies significantly enhanced the green index of high-efficiency water resource utilization in the basin.Furthermore,the integration of transfer payment policies for key ecological function zones and water rights trading policies contributed to some extent in promoting the coordination index of regional high-efficiency water resource utilization.
