摘　　要：2010年初的西南大旱凸显出西部地区水资源利用效率低下的现状。从分析西部12个省会城市入手,采用地区生产总值、固定资产投资总额、用水总量、用水人口等作为投入产出指标,首先运用数据包络分析法对西部12个省会城市2008—2009年的水资源利用效率进行分析和评价,然后运用Malmquist指数方法对2000—2009年西部11个省会城市(拉萨市暂未列入)的序列数据进行了分析。研究结果表明:(1)西部地区整体水资源利用效率低下且呈衰退之势,2000—2009年的TFP指数为0.955。(2)2008—2009年,重庆、西宁、乌鲁木齐和呼和浩特这4个城市达到了DEA有效,其它城市应参考这4个城市进行调整。成都、昆明、西安、兰州、银川和南宁市的生产规模过大,限制了水资源利用效率的提高。重庆、西宁、乌鲁木齐和呼和浩特这4个城市的生产规模应该保持稳定。贵阳和拉萨市应该加大生产规模。(3)科技是制约西部地区水资源利用效率的主要因素。提高水资源利用效率首先应该加大科技投入,优化产业结构;同时西部地区还应该加大水资源合理利用的宣传力度。Drought in the Southwest China in early 2010 highlights the situation of inefficient utilization of water resource in the western regions.This paper selects GDP,total investment in fixed assets,total water used,water-consumed population as input-output indicators,and takes data envelopment analysis method to evaluate the performance of water resource utilization in the 12 western capital cities in 2008 and 2009.Meanwhile,Malmquist TFP index method is used to analyze time series data from 2000 to 2009.The results are as follows：（1） The utilization of water resource in the western regions is inefficient and there is a declining trend.The total factor productivity（TFP） index of the utilization efficiency of water resource from 2000 to 2009 is 0.955.（2） During 2008 and 2009,Chongqing,Xining,Urumqi and Hohhot City are efficient based on DEA,and other cities should adjust according to the experience of the four cities above.The production scale in Chengdu,Kunming,Xi＇an,Lanzhou,Yinchuan and Nanning City are too large,thus it limit the utilization efficiency of water resource.The production scale in Chongqing,Xining,Urumqi and Hohhot City should remain stable while Guiyang and Lhasa should increase the production scale.（3） Technology is the dominant factor in restricting water using efficiency.So,investment in science and technology should be enhanced.In addition,expanding the scale of production and optimizing the industrial structure are also the indispensable way for improving the utilization efficiency of water resource.Finally,the western regions should also increase the propaganda on the rational utilization of water resource.
