摘要
以提高水资源利用效率为目标的节水举措,其有效性会受到水资源回弹效应的影响。以干旱地区甘肃省为例,构建可计算一般均衡(CGE)模型,测算生产用水效率分别提高1%、5%、10%时的水资源回弹效应,讨论生产用水效率提高所带来的经济效应和环境效应。结果表明:提高生产用水效率会促进甘肃省经济发展;甘肃省存在水资源回弹效应,且不同生产部门之间差异较大;从长期来看,各经济主体和各部门的水资源消耗量都随着生产用水效率的提高而出现不同程度的增加,回弹效应呈现出逐年增加趋势。
The effectiveness of water⁃saving measures aimed at improving water resources utilization efficiency will be affected by the rebound effect of water resources.This paper took Gansu Province as an example,and built Computable General Equilibrium(CGE)model to meas⁃ure the rebound effect of water resources when the production water efficiency was increased by 1%,5%and 10%respectively,and dis⁃cussed the economic and environmental effects of the improvement of water use efficiency.The results indicate that improving the water use efficiency of various production sectors will stimulate the economic development of Gansu Province.There is a rebound effect of water re⁃sources in Gansu Province,and there are large differences among different departments.In the long run,the water resources consumption of various economic agents and departments increase to varying degrees with the improvement of production water efficiency,and the rebound effect shows a trend of increasing year by year.
