Abstract:

To make full use of water resources and achieve ecological environment values, the undesirable outputs must be considered when we research water utilization efficiency. Using provincial panel data of China during 2003-2013, the green water utilization efficiency considering environmental pollution was measured with Malmquist-Luenberger productivity index. On this basis, cluster analysis and convergence tests of each region were made. The results showed that: 1) for the country as a whole, the dynamic green water utilization efficiency considering environmental constraints is lower than the water utilization efficiency without considering environmental constraints, namely the water resource utilization efficiency is overrated when ignoring undesirable outputs. This also shows that false high values of traditional water resources use efficiency are at the cost of ecological destruction. 2) The national dynamic green water utilization efficiency increased by 3.3%, in which technological progress has played a positive role, but technical efficiency is an obvious obstacle for improving the water use efficiency. 3) The green water utilization efficiency tend to steady growth in the whole country and in the eastern and central regions, but the growth of green water utilization efficiency in the western area is increasing. The growth rate of green water utilization efficiency in the western area is convergent but is not absolute convergent in β condition. Finally, we propose the following suggestions according to the research results: the economic value and ecological environmental value of water resources should be paid highly attention to; independent innovation and industrial structure adjustment also should be taken into consideration so as to enhance green water resources utilization efficiency by technological progress; the internal dynamic mechanism of water-saving and emission reduction should be established, and the regional gap of green water resources utilization should be reduced.
