摘要： 推动长江经济带高质量发展是关系国家发展的重大战略,提升城市群水资源绿色效率是保障生态优先绿色发展的基础性问题。在传统水资源利用效率研究中引入“绿色发展”概念,构建了水资源绿色效率评价指标方法体系,通过利用超效率EBM-DEA模型和面板Tobit模型对长江中游城市群水资源绿色效率进行了测算和影响因素分析。结果表明:①水资源经济效率受GDP变化影响较大,水资源环境效率和绿色效率的测度结果更符合实际情况;2009—2020年间,通过各城市圈对比发现,武汉城市圈的水资源绿色效率始终高于环鄱阳湖城市群与环长株潭城市群。②经济水平发达的城市水资源利用效率也高;长江中游城市群水资源充沛地区用水效率略低于水资源贫乏地区;高速的城镇化发展对水资源绿色效率具有抑制作用,因此长江中游城市群需坚持走绿色、新型的城镇化发展道路。

Abstract: The high-quality development of the Yangtze River Economic Belt constitutes a crucial strategy tied to overall national growth. Ensuring ecological priority and green development necessitates addressing the fundamental issue of improving the green efficiency of water resources in urban agglomerations. This study introduces the concept of “green development” into traditional research on water resources utilization efficiency. A comprehensive indicator system for evaluating the green efficiency of water resources is constructed. The super-efficiency EBM-DEA (Epsilon-Based Measure - Data Envelopment Analysis) model and panel Tobit model were employed to calculate and analyze the green efficiency of water resources in urban agglomerations in the middle Yangtze River. The findings reveal: 1) Changes in GDP have a significant impact on the economic efficiency of water resources, and the measurement results for the environmental efficiency and green efficiency of water resources are more reflective of actual conditions. From 2009 to 2020, comparisons among various city clusters reveal that the green efficiency of water resources in the Wuhan city cluster consistently outperformed that of the Poyang Lake urban agglomeration and Changsha-Zhuzhou-Xiangtan urban agglomeration. 2) Cities with thriving economies also exhibit high values of water resource utilization efficiency. Areas with abundant water resources in urban agglomerations in the middle Yangtze River demonstrate slightly lower water use efficiency than areas with scarce water resources. Rapid urbanization exerts a restraining effect on green efficiency of water resource, underscoring the need for urban agglomerations in the middle Yangtze River to adhere to a green and new type of urbanization development path.

Key words: green efficiency of water resources, urban agglomeration in middle Yangtze River, super-efficiency EBM-DEA model, Tobit model
