Influence Mechanism of Digital Economy Development on Total Factor Energy Efficiency:Taking 73 Prefecture-level Cities in the Yellow River Basin as Examples
This paper calculates the digital economy and total factor energy efficiency from 2011 to 2020 using the Gini coef-ficient objective empowerment evaluation method and the undesired SBM model,respectively.With the help of the bench-mark model,this paper empirically tests the role of the digital economy in improving total factor energy efficiency,examines the effects played by the three pathways of digital industry agglomeration,technological innovation,and environmental regu-lation in the transmission process,and analyzes the regional heterogeneity in the upper,middle and lower reaches of the Yellow River Basin.The results show that:(1)The promotion effect of the digital economy is most obvious in total factor energy efficiency in the midstream.(2)The key positive transmission paths in the Yellow River basin are Industrial agglom-eration,technological progress,and environmental regulation.(3)Heterogeneity analysis shows that technological progress is positively mediated in the upstream,midstream,and downstream,while environmental regulation shows negative trans-mission in the midstream and positive transmission in the downstream.
