摘要
基于2000−2018年全国30个省份(港澳台、西藏除外)的面板数据,利用面板回归模型和中介效应模型分析了产业结构升级、全要素能源效率及碳排放之间的关系和影响机制。研究发现:产业结构高级化在不同区域对碳排放均呈现显著的抑制作用,不同区域的抑制强度呈现“西部>中部>东部”的规律;产业结构合理化在不同区域对碳排放的抑制作用差异较大,在中西部地区表现为显著的抑制作用,但在东部地区抑制作用不显著;各区域全要素能源效率的提升对碳排放的抑制作用均较为显著,抑制强度呈现“西部>东部>中部”的规律。进一步通过中介检验发现,不同区域的全要素能源效率在产业结构升级与碳排放的作用中具有部分和完全中介效应,能够促进和加强产业结构升级对碳排放的抑制作用。因此,研究认为产业结构升级和提升全要素能源效率是促进碳减排的有效手段,但单独依赖产业结构升级的碳减排效果并不理想,需与提升全要素能源效率相结合才会对碳减排起到有效的促进作用。
Based on the panel data of 30 provinces in China from 2000 to 2018,the mutual relationships and mechanisms of influence between industrial upgrading,total factor energy efficiency and regional carbon emission were investigated.The results show that the sophistication of industrial structure has a significant inhibitory effect on carbon emissions in all regions.The intensity of inhibition in different regions shows a sequence of“western>central>eastern”.The inhibitory effect of the rationalization of industrial structure on carbon emissions varies greatly among the different regions,with a significant restraining influence in the central and western regions,but much less influence in the eastern region.The inhibition of carbon emissions through the improvement of total factor en-ergy efficiency is significant in all regions,and the inhibition intensity shows the sequence of“western>eastern>central”.Furthermore,the mediating effect test shows that the total factor energy efficiency in different regions has either a partial or complete mediating effect on the influence of industrial upgrading on carbon emission,so it can promote and strengthen the inhibitory effect of industrial upgrading on carbon emissions.Therefore,upgrading the industrial structure and improving the total factor energy efficiency are effective means to promote carbon emission reduction.Reducing carbon emissions by relying solely on industrial upgrading is not ideal,and it needs to be combined with improvements in the total factor energy efficiency to effectively promote carbon emission reduction.
