Abstract: By setting up an inputs price system based on regional factor endowments, we added factor endowments into the analysis framework of industrial water efficiency by employing cost- efficiency DEA model, and calculated China's regional industrial water efficiency from 2002 to 2011 and examined regional convergence tendency. Calculated results showed that almost every region's industrial water efficiency was rising continuously, but regional disparities were huge that three distinct echelons were easy to distinguish. Most regions' inputs structure do not match with their own endowment characteristics. The eastern and central regions' capital investment proportions were generally lower than the optimal level while their water input proportions were generally higher than the optimal level. The western regions' labor input proportions were generally lower than the optimal level while their water input proportions were generally higher than the optimal level. Convergence test results showed that regional industrial water efficiency did not show a strong convergence trend as capital efficiency and labor efficiency did, but both high water efficiency areas and low water efficiency areas exist club convergence. Our findings provide several important enlightenments to improve China's industrial water efficiency. This article provides a more practical analytical framework for the study of resource utilization efficiency by employing cost-efficiency DEA model and factor endowments theory, which may inspire more in-depth researches.
