Analysis of the Impact of Industrial Structure Upgrading and Energy Structure Optimization on Carbon Emission Reduction

In China, there has been a significant increase in carbon emissions the new era. Therefore, evaluating influence of industrial structure upgrades and energy optimization on reducing is objective this research. Based provincial panel data 30 provinces cities across China from 1997 to 2019, paper builds up fixed-effect quantile STIRPAT model investigate differences impact emission intensity at different levels perspective, as way causality test, mediation effect adopted empirically test transmission path “industrial upgrading—energy optimization—carbon reduction”. The research results show that: (1) Both have inhibitory effects emissions, are regional heterogeneities. (2) upgrading positive optimizing structure. (3) can not only directly restrain but also indirectly by promoting above conclusions, corresponding policy recommendations proposed provide suggestions for achieve goal neutrality.
