The impact and spatial effects of the digital economy on carbon emission efficiency in the Changsha-Zhuzhou-Xiangtan metropolitan area
The digital economy is a pivotal driver for fostering high-quality economic development in China,which is crucial in attaining carbon peak and neutrality objectives.Given its significance as a core vehicle for national urbanization initiatives,elucidating the influence and spatial implications of the digital economy on carbon emission efficiency at the county and district levels is imperative for China's new urbanization strategy,bolstering ecological civilization and advancing green transformation and development in the contemporary era.Utilizing the entropy weight method and the SBM-DEA model,this study assessed the digital economy's development level and carbon emission efficiency in 19 counties within the Changsha-Zhuzhou-Xiangtan metropolitan area spanning 2011 to 2021.Spatial analysis techniques were employed to delineate the spatiotemporal patterns and clustering characteristics of the digital economy and carbon emission efficiency at the county scale within this metropolitan region.Furthermore,we leveraged the OLS model and the spatial Durbin model to empirically scrutinize the impact and spatial effect of the digital economy on carbon emission efficiency in the study area.The key findings are as follows:(1)There exists a significant disparity in the development of the digital economy and carbon emission efficiency across the Changsha-Zhuzhou-Xiangtan metropolitan area,exhibiting a spatial distribution pattern characterized by"high in the north and low in the south".(2)The digital economy in this metropolitan area consistently exerts a noteworthy stimulatory effect on carbon emission efficiency,and this influence is markedly strengthened upon the inclusion of various control variables.(2)The digital economy in the Changsha-Zhuzhou-Xiangtan metropolitan area exhibits a substantial positive spatial effect on carbon emission efficiency,with a more significant impact on local carbon emission efficiency compared with neighboring counties.
