Research on carbon emission efficiency and influencing factors of cement industry in Beijing-Tianjin-Hebei under the"double carbon"goal
With the proposal of the dual-carbon strategy,it has great practical significance to study the carbon emission efficiency and influencing factors of the cement industry for the realization of the dual-carbon goal in Beijing-Tianjin-Hebei.In this paper,the super-subject-bench-marking(Super-SBM)model,which considers carbon emissions as unexpected output,is used to calculate the carbon emission efficiency of the cement industry in Beijing-Tianjin-Hebei from 2010 to 2022.After that,structural vector autoregression(SVAR)model is selected to explore the influencing factors of carbon emissions of the cement industry in Beijing-Tianjin-Hebei.The results show that the average carbon emission efficiency of the cement industry in Beijing-Tianjin-Hebei is in an inefficient state,and the carbon emission efficiency has obvious differences and shows an unstable fluctuation trend;In the short term,increasing the proportion of non-coal energy consumption will help the cement industry in Beijing-Tianjin-Hebei to reduce carbon emissions.In the medium term,economic growth will also contribute to the improvement of carbon productivity.In the long run,the most conducive to carbon emission reduction is the continuous optimization of energy production and the continuous adjustment of energy structure.
