摘　　要：运用基于DEA的Malmquist指数方法对我国31个地区"十一五"时期水利投资效率的变化趋势进行分析。研究结果表明:2006—2010年我国水利投资全要素生产率的平均值为1.152,从整体上看呈现逐年递增的趋势。对全要素生产率进行了分解,发现技术效率偏低为0.844,技术进步表现良好为1.568,纯技术效率变化不大,规模效率偏低为0.846。说明全要素生产率的增长主要来自技术进步的提高,水利投资技术效率偏低主要是由于较低的规模效率造成,应适当扩大水利工程建设的规模。从区域的角度来看,西部地区的水利投资效率优于东部和中部地区。The Malmquist index based on the DEA model is used to analyze the trend of water investment efficiency in 31 provinces(Municipalities and autonomous regions) in China during the 'Eleventh Five-year Plan'period. The results show that the total factor productivity of water investment generally has a gradual increase from 2006 to 2010,with the average being 1. 152. The total factor productivity is divided into several sections,and it is found that the technical efficiency,0. 844, is low, the technical progress,1. 568,is satisfactory,the pure technical efficiency changes little,and the scale efficiency,0. 846,is low. It indicates that the growth of the total factor productivity mainly results from the improvement of the technical progress. The low technical efficiency of water investment is induced by the low level of scale efficiency. The construction scale of hydraulic projects should be reasonably expanded. From the regional perspective,the efficiency of water investment in the western region of China is better than that in the eastern and central regions.
