摘要: 在“双碳”目标与绿色转型的发展背景下，数字经济对能源效率的影响具有重要研究价值。本文以2011~2023年中国30个省级行政区为样本，采用DDF-SFA模型测度全要素能源效率，经自适应弹性网筛选与熵权法测算数字经济综合指数，通过基准回归、中介效应模型及异质性分析展开实证检验。结果表明，数字经济对全要素能源效率具有显著正向净效应，该结论通过内生性及稳健性检验；技术研发能力与政府创新支持是数字经济赋能能源效率提升的关键中介路径。数字经济的正向赋能效应存在显著区域异质性，仅在小省份、低经济水平省份、偏服务业省份显著。
Abstract: Against the backdrop of the dual-carbon goals and green transformation, the impact of the digital economy on energy efficiency carries important research value. This paper takes 30 provincial-level administrative regions in China from 2011 to 2023 as the research sample, and adopts the DDF-SFA model to measure total factor energy efficiency. The adaptive elastic net model is used for indicator screening and the entropy weight method for calculating the comprehensive digital economy index, with empirical tests conducted through benchmark regression, mediating effect model and heterogeneity analysis. The results show that the digital economy exerts a significant positive net effect on total factor energy efficiency, a conclusion verified by endogeneity and robustness tests; technological research and development capability and government innovation support are the key mediating paths through which the digital economy boosts energy efficiency improvement. The positive enabling effect of the digital economy exhibits significant regional heterogeneity, being only prominent in small provinces, provinces with low economic development levels, and service-oriented provinces.
