Abstract：The digital economy possesses a dual effect of promoting high-quality economic development and environmental improvement.Therefore,this study employs panel data from nine provinces in the Yellow River Basin from 2011 to 2021 as samples.It utilizes various methods such as Entropy Method,Coupling Coordination Model,Kernel Density Estimation,Moran's Ⅰ Index,and standard deviational ellipse to investigate the temporal and spatial evolution characteristics of the coupling coordination degree between the digital economy and carbon emission reduction capabilities.The results indicate that:① Both the digital economy and carbon emission reduction capabilities in the Yellow River Basin have shown a steady growth trend from 2011 to 2021.② The degree of coupling coordination is increasing year by year,and the number of provinces moving into the coordination stage is gradually increasing.③ Spatially,the coupling coordination degree exhibits a significant positive spatial correlation,but the correlation shows a fluctuating downward trend.④ The standard deviation ellipse is distributed in a northeast-southwest direction,with its center located in Shaanxi and migrating towards the northwest overall.The area of the ellipse has expanded slightly.
