摘要

Under the strategic goals of ecological protection and high-quality development, whether the Yellow River Basin (YRB) can efficaciously enhance its carbon emission efficiency (CEE) via green technology innovation (GTI) bears significant practical implications for attaining a win-win situation of “green” and “wealth.” Using panel data from 9 provinces in the YRB from 2007 to 2021, this study employs standard deviation ellipse analysis to examine the spatial pattern and temporal evolution of CEE in the region. And it also applies the spatial Durbin model to explore how GTI influences CEE from the perspectives of inventive green technology innovation (INGTI) and improved green technology innovation (IMGTI). Additionally, the study explores the moderating role of industrial agglomeration (IA) in this relationship. The results reveal that the CEE in the YRB is distributed from southwest to northeast, with clustering in the east-west direction. CEE’s center of gravity generally moves towards the northeast of the basin, with an overall stable evolutionary trend. In the YRB, both INGTI and IMGTI can effectively enhance the CEE of neighboring provinces while promoting local CEE. However, their impacts are spatially heterogeneous. In upstream provinces, INGTI has a stronger effect on CEE than IMGTI, whereas in lower-middle stream provinces, the enhancing effects are consistently well demonstrated. Additionally, IA exhibits significant moderating effects, which vary according to the type of GTI. It exerts a significant negative linear moderating effect on the CEE enhancement from INGTI, while demonstrating a U-shaped moderating effect on the CEE improvement from IMGTI. Furthermore, this study presents corresponding policy recommendations to the above results.
