%X The drought which occurred over southwestern China in the early 2010 highlights the situation of inefficient utilization of water resources over these regions. Although it resulted in part from natural factors, people are more clearly aware that the water ecosystem across the region is generally vulnerable, and the ability of drought control is weak. Inadequate infrastructure construction associated with reserving and allocating water resources, which is indispensible to mitigate the uneven spatial and temporal distribution of water resources over there, appears to aggravate water crisis in this region. This paper attempts to examine causes of low efficiency of water utilization across the western regions of China and solutions on how to deal with the grim situation. First, we selected GDP, total investment in fixed assets, annual water supply, and population using water as input-output indicators, and made use of data envelopment analysis to investigate the performance of water resources utilization in 12 western provinces in years 2007 and 2008. Subsequently, we analyzed time series data of the 12 western provinces from 1999 to 2008 using the Malmquist total factor productivity index method. The innovation of this work lies in the dynamic process of analysis. Results show that the utilization efficiency of water resources in Sichuan, Shanxi, Xinjiang, Inner Mongolia, and Guangxi is slightly higher. In order to effectively address an acute shortage of water, other provinces can refer to the experience of the five provinces. Tibet, in particular, should make more efforts to improve the water use efficiency. The total factor productivity index of the utilization efficiency of water resources across western China was found to be 0.956. This means a decreasing trend in water utilization efficiency year by year. Furthermore, the results indicate that technology is the dominant factor restraining water use efficiency for the 12 western provinces. Some suggestions are given including increasing investment in science and technology to improve the overall utilization efficiency of water resources, and expanding the scale of production and optimizing the industrial structure. This paper provides a basis for formulating reasonable water exploitation and protection strategies and policies and would be helpful for achieving the sustainable and coordinated development of resources, economy, and society in western China.
