京津冀碳排放效率的提升策略OA

The problem of environmental pollution has long restricted the coordinated development of the Beijing-Tianjin-Hebei Urban Agglomeration.To explore the spatiotemporal distribution characteristics of carbon emission efficiency,this paper employs the super-efficiency SBM model and the GML index model to analyze the carbon emission efficiency of the region during the period from 2011 to 2022.On the whole,the carbon emission efficiency of the Beijing-Tianjin-Hebei Urban Agglomeration has shown an upward trend,with the contribution of technological progress exceeding that of technical efficiency.However,the overall level remains relatively low.In terms of spatial pattern,the carbon emission efficiency in the Beijing-Tianjin-Hebei Urban Agglomeration presents a distribution characteristic of being higher in the east than in the west and higher in the north than in the south.In terms of influencing factors,energy intensity has a significant inhibitory effect on the carbon emission efficiency of this region and its neighboring regions,while the increase of the proportion of the secondary industry has an inhibitory effect on the local carbon emission efficiency,but it has a positive spatial spillover effects on the carbon emission efficiency of neighboring regions.
