摘　　要：探究黄河流域城市群数字化水平对绿色经济效率的影响,对于促进黄河流域生态保护和高质量发展具有重要意义。本文探讨了城市群数字化水平对绿色经济效率的直接和间接影响机制,并通过空间滞后Tobit模型估计了其影响效果。研究发现,黄河流域城市群数字化水平对绿色经济效率具有显著正向影响,并通过推动绿色创新和产业结构高级化间接提升绿色经济效率;此外,黄河流域城市群数字化水平会负向调节政府干预对绿色经济效率的促进作用,会正向调节基础设施水平对绿色经济效率的促进作用。数字化水平对黄河流域中游和下游地区城市群绿色经济效率具有显著的促进作用,而对上游城市群绿色经济效率的促进作用不明显,存在区域异质性。It is of great significance to explore the influence of digitization level on green economy efficiency of urban agglomerations in the Yellow River Basin for promoting ecological protection and high-quality development of the Yellow River Basin.The paper discusses the direct and indirect influence mechanism for digitization level of urban agglomerations on green economy efficiency,and estimates the effect of digitization level of urban agglomerations on green economy efficiency by the spatial lag Tobit model.It is found that the digitization level of urban agglomerations in the Yellow River Basin has a significant positive impact on green economic efficiency and can indirectly improve green economic efficiency by promoting green innovation and upgrading of industrial structure in urban agglomerations.In addition,the digitization level of urban agglomerations in the Yellow River Basin negatively moderates the positive impact of government intervention on green economic efficiency.It will positively regulate the promoting effect of infrastructure level on the efficiency of green economy.The digitization level of urban agglomeration has a significant promoting effect on the green economic efficiency in the middle and lower reaches of the Yellow River Basin;but the promoting effect on the green economic efficiency of urban agglomerations in the upper reaches is not obvious,and there is regional heterogeneity.
