中国地表水资源利用效率区域差异研究

Abstract In this paper China's 31 provinces and autonomous regions are divided into abundant surface water resources area relatively abundant surface water resources area and water resources scarce area. Data envelopment analysis (DEA) method is used to studythe surface water resources efficiency in 2010. Research shows that the surface water resources in the 31 provinces and regions aredifferent. The utilization efficiency of surface water resources scarce area is higher and the surface water use efficiency and the localeconomic development level is not necessarily linked.院地表水资源 利用效率 数据包络分析法 区域差异Key words surface water resources utilization efficiency data envelopment analysis regional differences中图分类号院P641.8 文献标识码院A 文章编号院1006-4311（2014）15-0030-030
