The improvement of water resources utilization efficiency is of great importance to alleviate the conflict between water resources supply and demand. In this paper, 10 municipalities in the main stream of Hanjiang River Basin was selected, the water resources utilization efficiency from the year of 2008 to 2015 was analyzed by using the method of data envelopment method(DEA). Subsequently, the total-factor productivity with its compositional index of water resources green efficiency was illustrated in detail by using Malmquist index model. The results show that the water resources utilization efficiencies of different cities in the main stream of Hanjiang River had the characteristics of temporal and spatial variability, the water resources economic efficiencies of cities in the middle and lower reaches were generally higher than those of the cities in the middle and upper reaches; the economic developments of cities with a higher water resources green efficiencies were relatively slower and concentrated in the downstream areas of Hanjiang River Basin; from 2008 to 2015, the water resources economic efficiency gradually decreased, while the water resources green efficiency increased first and then decreased; except that the total factor productivities of Wuhan and Ankang had maintained a positive and favorable development trend, the total factor productivities of other cities were mainly affected by technical constraints and scale effect. These research results can provide a reference for the optimal allocation of water resources.
