摘　　要：建立了水资源效率DEA模型,以农业用水、工业用水、生活用水、生态用水、就业人数及固定资产投资为输入指标,以GDP为输出指标,对我国31个省、区、市2010年水资源利用效率进行分析,探讨我国各省份的水资源利用效率以及投入冗余情况,为将来的水资源利用政策和决策提供支持。结果表明,2010年没有达到DEA有效的省级地区约占2/3,河北、辽宁、浙江等13个地区投入冗余,产出不足,内蒙古、广东、江西等7个地区规模不匹配。农业用水和劳动力要素过多投入,影响了水资源利用效率改进,生态用水的利用效率则相对较高。基于以上分析,利用DEA投影下的有效目标值对各类用水资源的投入参量进行调整,实现了水资源的最优配置。This paper establishes a DEA model for water resources efficiency, taking agricultural water, industrial water, living water, ecological water, total employment and fixed asset as input parameter and GDP as output parameter. To provide support for future policy and decision-making of water resources utilization, this paper explores water utilization efficiency and input redundancy of 3 l provincial regions in China for the year of 2010. The results show that about 2/3 of the regions＇ DEA is not valid, meaning input redundancy and output lack in 13 regions, such as Hebei, Liaoning, Zhejiang, etc. and scale mismatching in 7 regions, such as Inner Mongolia, Guangdong, Jiangxi, etc.. Too much input of agricultural water and labor directly affect the effective use of resources. In contrast, the use efficiency of ecological water is high. DEA projection results can achieve an optimized water resources allocation.
