摘要: 选取2002—2017年长江三角洲区域(长三角地区)3省1市的用水总量、固定资产投资总额、就业人数、废水排放量4个投入量及GDP产出量,构造了DEA-Malmquist指数模型,结合环境因素对其绿色用水效率进行了剖析。结果表明,3省1市的绿色用水效率在2010年和2015年处于明显的转折点,显示出节水政策和水污染治理政策落实的重要性;研究期间TFP全要素指数大于1,但技术效率呈现不变甚至退步的趋势,其中安徽省最为明显。因此指出在落实节水政策、保证技术进步、扩大产业规模的同时也要注重产业结构的优化。

Abstract: The total water consumption, fixed assets investment, employment figure, amount of discharged wastewater and GDP output of three provinces and one city in the Yangtze River Delta from 2002 to 2017 were choosed to construct the DEA-Malmquist index model. The green water efficiency of the provinces was analysed,combining with environmental factors. The result showed that year 2010 and year 2015 were two obvious turning points of green water efficiency in three provinces and one city, which showed the significance of water conservation and water pollution governance policy implementation; During the study period, TFP total factor index was greater than 1, but technical efficiency showed a regressive trend, especially in Anhui Province. Therefore, the provinces should pay attention to optimizing industrial structure while implementing water-saving policies, ensuring technological progress and expanding industrial scale.

Key words: green water efficiency, DEA and Malmquist index, economies of scale, environmental protection, Yangtze river delta region
