摘　　要：为推动黄河流域水资源节约集约利用,促进黄河流域走绿色可持续的高质量发展之路,亟须进一步统筹研判、有效提升黄河流域水资源绿色效率。基于黄河流域58个地级市2011—2019年的面板数据,从内部竞争视角,研究黄河流域水资源绿色效率及影响因素。引入二阶段DEA博弈交叉模型分析得出:黄河流域水资源绿色效率较高,呈现下降上升再下降趋势,区域间、地级市间效率水平、变化幅度差异较大。构建Tobit模型分析得出:对外开放程度对水资源绿色效率影响较小,产业结构对其有负面影响,经济发展水平和环境规制对其均有正面影响,上述因素对各区域的影响存在差异。提出了黄河流域统筹治理,对资源类、工业升级型城市分类推进经济发展和水资源治理,细化实化责任、强化重工业等各领域环境污染系统治理,加大科技投入、发挥技术进步对水资源绿色效率的提升作用等政策建议。In order to promote the conservation and intensive utilization of water resources in the Yellow River Basin and promote the green,sustainable and high⁃quality development of the Yellow River Basin,it is urgent to further coordinate and effectively improve the green efficien⁃cy of water resources in the Yellow River Basin.In this paper,a two⁃stage DEA game crossover model using the panel data of 58 prefecture⁃lev⁃el cities in the Yellow River Basin from 2011 to 2019 was introduced to estimate and analyze water resources green efficiency in the Yellow Riv⁃er Basin from the perspective of internal competition among cities.Analysis by the two⁃stage DEA game crossover model revealed that the green efficiency of water resources in the Yellow River Basin is relatively high,showing a downward and later upward and then downward trend.There are significant differences in efficiency levels and changes between regions and prefecture⁃level cities.Analysis by a Tobit model finds that the degree of openness to the outside world has a relatively small impact on the green efficiency of water resources,while the industrial structure has a negative impact on it.The level of economic development and environmental regulations have a positive impact,and the impact of these factors on different regions varies.This paper puts forward policy suggestions on coordinated management of the Yellow River Basin,promoting econom⁃ic development and water resources management by classifying resources⁃based and industrial upgrading cities,refining practical responsibilities and strengthening the systematic governance of environmental pollution in various fields such as heavy industry,strengthening investment in sci⁃ence and technology,and giving play to the role of technological progress in improving the green efficiency of water resources.
