低碳能源技术创新对碳排放效率的影响研究OA北大核心CHSSCDCSSCICSTPCD

As the foremost emitter of carbon,China faces an imperative to expeditiously achieve its carbon peak goal by bol-stering carbon efficiency in the background of climate change.Low－carbon energy technology innovation(LCETI),recognized as a pivotal strategy in addressing climate change,harbors substantial potential for emission reduction and efficiency enhancement.Therefore,this study investigates the relationship between LCETI and carbon efficiency in China with the spatial Durbin model,in-cluding spatial spillover,moderating,and heterogeneity effects based on data from 286 cities between 2006 and 2022.The main conclusions show that LCETI can both directly increase carbon efficiency in local areas and indirectly accelerate carbon efficiency in surrounding areas.Besides,the promotion of industrial structure optimization,environmental regulation,and technological support has a positive moderating effect of LCETI on carbon efficiency.Moreover,LCETI in western China has significant effects on the car-bon efficiency of the local and surrounding areas.Finally,the innovation of nuclear energy and hydropower technology has the most significant effect in local areas.In contrast,the innovation of geothermal and biomass energy technology has the most significant effect in the surrounding areas.The results of this study help the government and scholars to scientifically utilize low－carbon energy technologies to enhance the collaborative carbon reduction capacity of Chinese society.
