    摘要:

    提高绿色水资源效率不仅可以有效降低水资源消耗,还有助于促进绿色发展、推进我国经济转型升级。采用包含非期望产出全局参比的SE-SBM模型核算出我国31省份2000-2017年的绿色水资源效率,并结合Tapio脱钩模型,研究水资源消耗、绿色水资源效率与经济增长之间的“脱钩”问题。研究发现:(1)2000-2017年我国绿色水资源效率整体均值为0.852,整体呈现为上升趋势,年平均增长率为5.39%;(2)从区域层面来看,东部地区年平均增长率为6.18%,中部地区为5.37%,西部地区为4.53%,东北地区为4.79%;(3)从水资源消耗来看,我国水资源消耗与经济增长脱钩关系整体表现为弱脱钩;(4)从绿色水资源效率来看,我国绿色水资源效率与经济增长2000-2005年、2006-2010年主要为弱脱钩关系,2011-2017年主要为弱脱钩关系,同时扩张性负脱钩关系表现突出。因此,我国应提高科学技术水平,构建严格的管理制度,坚持产业改革创新,以推进水资源消耗与经济增长的强脱钩及绿色水资源效率与经济增长的扩张性负脱钩的实现进程。

    Abstract:

    Improving the efficiency of green water resources can not only effectively reduce water consumption,but also help promote green development and China’s economic transformation and upgrading.Using the SE-SBM model containing the global reference of undesired outputs to calculate the efficiency of green water resources in China’s 31 provinces from 2000 to 2017,this paper discussed the decoupling problem between water consumption and the efficiency of green water resources and economic growth by the Tapio decoupling model.The study found that:1)from 2000 to 2017,the overall average efficiency of China’s green water resources was 0.852,and the overall performance showed an upward trend with an average annual growth rate of 5.39%; 2)from a regional perspective,the average annual growth rate in the eastern region is 6.18%,followed by 5.37% in the central region,4.53% in the western region,and 4.79% in the northeast region; 3)from the perspective of water consumption,the overall decoupling relationship between China’s water consumption and economic growth is weak decoupling; 4)from the perspective of green water resources efficiency,China’s green water resource efficiency and economic growth are mainly weak decoupling between 2000 and 2005,2006 and 2010; the year between 2011 and 2017 is also featured by weak decoupling and the expansionary negative decoupling relationship is outstanding.Therefore,China should accelerate the development of science and technology,build a strict management system,and adhere to industrial reform and innovation to promote the strong decoupling between water consumption and economic growth,and the realization of the expansionary negative decoupling between green water use efficiency and economic growth.
