摘　　要：为探索数字经济发展对黄河流域能源效率的影响以及内在影响机制,依据2011—2021年黄河流域80个地级市的面板数据,运用三阶段DEA方法测度能源效率,采用熵值法测度数字经济发展水平,以数字经济发展水平为解释变量,以能源效率为被解释变量,以金融发展水平、城市人口规模、政府财政支出、科技支出水平、城镇化水平为控制变量,以技术创新水平、产业结构升级水平、环境规制强度为中介变量,以经济发展水平为调节变量,构建个体固定效应模型,实证检验数字经济发展对能源效率的影响,并进行了中介效应、调节效应和异质性分析。结果表明:1)数字经济发展对黄河流域能源效率具有先抑后促的U形影响,当前黄河流域的数字经济发展还处于对能源效率的抑制期;2)技术创新、产业结构升级、环境规制在数字经济对能源效率的影响中发挥部分中介作用;3)经济发展水平在数字经济发展与能源效率之间的U形关系中有负向调节作用,即数字经济发展对能源效率的影响随经济发展水平的提高而弱化;4)数字经济发展对能源效率的影响存在区域异质性和经济发展水平异质性,当前上游地区数字经济发展促进能源效率提升的城市相对较多、中游次之、下游相对较少,经济发展相对落后地区数字经济发展对能源效率的U形影响较经济发展相对发达地区更为明显。文末提出了相关对策建议。In order to explore the impact of digital economic development on energy efficiency in the Yellow River Basin and its internal influ⁃ence mechanism,based on the panel data of 80 prefecture⁃level cities in the Yellow River Basin from 2011 to 2021,the three⁃stage DEA method was used to measure energy efficiency,and the entropy method was adopted to measure the development level of the digital economy.Taking the development level of the digital economy as the explanatory variable and energy efficiency as the explained variable,taking the level of financial development,the size of urban population,government fiscal expenditure,the level of science and technology expenditure,and the level of urbanization as control variables,the level of technological innovation,the level of industrial structure upgrading,and the in⁃tensity of environmental regulation as mediating variables,and the level of economic development as moderating variables,an individual fixed effect model was built to empiratically test the impact of digital economic development on energy efficiency.And the mediating effect,modera⁃ting effect and heterogeneity analyses were conducted.The results indicate that a)the development of the digital economy has a U⁃shaped im⁃pact on the improvement of energy efficiency in the Yellow River Basin,with an initial inhibitory effect followed by a promotional effect.Cur⁃rently,the level of digital economy development in the Yellow River Basin still inhibits the enhancement of energy efficiency.b)Technologi⁃cal innovation,industrial structure upgrading,and environmental regulation partially mediate the impact of the digital economy on energy effi⁃ciency.c)The level of economic development negatively moderates the U⁃shaped relationship between digital economy development and ener⁃gy efficiency,meaning that the impact of digital economy development on energy efficiency diminishes as the level of economic development increases.d)The impact of digital economy development on energy efficiency exhibits
