Evaluation and Spatio-Temporal Analysis of Carbon Emission Efficiency Based on Super-Efficiency EBM Model
This paper utilizes carbon emission data from 2014 to 2019 across provinces in China,employs the Su-per-Efficiency EBM and GTWR models to assess provincial carbon emission efficiency and analyze its spatiotem-poral correlations.Findings reveal significant disparities in provincial carbon emission efficiency,with a spatial positive correlation,showing that the carbon emission efficiency in the eastern region is notably higher than other regions.Analysis from the GTWR model indicates an increasingly apparent role of optimizing the secondary in-dustry structures and reducing GDP energy consumption in improving carbon emission efficiency.Spatial hetero-geneity analysis suggests that enhancing openness significantly promotes the transition to a low-carbon economy in the southwest,while the eastern region should focus on enhancing economic effects and leveraging ownership advantages to further improve carbon emission efficiency.The central,northwest,and northeast regions should ac-tively consider enhancing carbon emission efficiency through optimizing the secondary industry structure and en-ergy consumption structures.
