Water resource plays an important strategic role in supporting social and economic development. In china, there exist many problems in water use, such as sharp contradiction between supply and demand, serious waste of water resource, water pollution. Low efficiency of water use is an important factor in these problems. Promoting the scientific and efficient use of water resource is an urgent need for the healthy and sustainable development. This paper studies the water use efficiency among large and medium-sized cities in China from 2004 to 2014. The water use efficiency is obtained by data envelopment analysis methodology, with water, labor employment and total investment in fixed assets as input indicators, and with GDP as output indicator. The water use efficiency presents different characteristics for the cities studied. And the research analyzes and evaluates the differences and the change trends of water use efficiency of the cities in the study period. Then, the Tobit regression is performed to estimate the effects that many social and economic factors have on water use efficiency, such as economic development, industry structure, urbanization level, technological factors and natural factors. The study suggests that industrial structure optimization and the adoption of advanced technologies have significant effects on the utilization efficiency of water resource. In addition, some specific advice will be given to improve the water use efficiency for cities in China, which contribute to increase water use efficiency and sustainable development.
