Abstract: The sustainability of water resource utilization is not only conducive to sustainable social and economic development,but also conducive to protection of ecological environment health.In this paper,we constructed a DEA-Malmquist evaluation model of water resource utilization efficiency,and apply it to analyze water use efficiency of seven major basins(Yangtze River basin,Yellow River basin,Pearl River basin,Haihe River basin,Huaihe River basin,Songhuajiang River basin and Taihu Lake basin)from static and dynamic perspectives in China from 2008 to 2017.The results showed that:(1) The overall water use efficiency of the seven basins in China was relatively high.There were obvious differences of water use efficiency between basins(highest in Haihe River basin and lowest in Yangtze River basin).(2) Technological progress,scale efficiency and pure technology efficiency had negative effect on the water use efficiency increase of the seven basins in China,and the scale efficiency had the most obvious restrain on water use efficiency.The research could provide reference for water-saving society establishment and sustainable water resource use.
