摘要
Abstract
The realization of the most stringent water resources management and the construction of water ecological civilization rely on the improvement of water resources utilization efficiency. So, the understanding of regional water utilization efficiency is necessary. By using DEA( Data Envelopment Analysis) model and taking the GDP of 11 provinces in Changjiang Economic Belt as output index, the fixed asset investment, the amount of agriculture water, industry water, domestic water, ecological water and the employed population are selected as the input index, the water resources use efficiency of 11 provinces( cites) in 2004 and 2012 are analyzed and compared, and the variation trend of water resources use efficiency from 2004 to 2012 is analyzed by Malmquist index. The analysis results show that the general trend of water resources use efficiency in Changjiang Economic Belt is in a downward tendency;the water resources use efficiency of Shanghai City, Zhejiang Province and Sichuan Province are high-er relatively;the main factors restricting the water resources use efficiency is technology development. So, the reinforcement of technology renovation and application is the key route to improve water resources use efficiency.关键词
