摘要:

利用SBM模型(slack based model)计算2004—2018年长江经济带水资源绿色效率,并与传统的经济效率、环境效率测度结果进行比较,分析其动态变化规律,然后分别利用Morans I指数、空间杜宾模型分析其空间自相关性和空间溢出效应,以期确定水资源绿色效率的影响机制,为促进长江经济带水资源绿色利用与优化配置提供参考。研究表明:长江经济带水资源绿色效率呈波动下降趋势,上游、中游地区下降趋势明显;水资源绿色效率存在空间集聚效应;邻省的经济水平、环境规制、工业化水平、第三产业占比对水资源绿色效率有明显抑制作用,而邻省的对外开放水平、城镇化水平、资源禀赋、农业用水比重有正向的空间溢出效应。因此,建议建立长江经济带生态环境协同治理机制,提高对外开放水平,加强城镇化建设,完善交通基础设施,加大对环境治理的资金与技术投入。

Abstract:

This paper utilizes SBM(slack based model) to estimate the green efficiency of water resources in Yangtze river economic zone from 2004 to 2018, which is compared with the traditional economic efficiency and environmental efficiency to study its dynamic changes. Morans index and spatial Dubin model are employed to analyze its spatial autocorrelation and spatial overflow effect to determine the factors influencing water resources green efficiency, in an attempt to promote green use and optimized allocation of water resources in Yangtze river economic zone. Study shows that the green efficiency of water resources in Yangtze river economic zone is declining windingly, more in upper\| and middle\|stream. The green efficiency of water resources is also of spatial concentration, obviously constrained by its vicinities in economy, environmental regulations, industrialized level and proportion of the third industry, but spatially overflowed in openness, urbanization, resources and agricultural water use rate. This paper presents suggestions on establishing mutual management of eco\|environment, boosting openness, intensifying urbanization, improving infrastructures and increasing capital and technical inputs.

Key words: green efficiency of water resources, SBM model, Morans index, spatial Dubin model
