Research on Carbon Emission Efficiency and Impact of Construction Industry in National Central Cities
National central cities are at the highest level of China's urban system,and studying their carbon emission efficien-cy in the construction industry is of great practical significance for achieving high-quality goals of peak carbon dioxide emis-sions and carbon neutrality.Firstly,based on super efficiency SBM model,it concluded that the overall carbon emission effi-ciency of the construction industry in national central cities was relatively low,and efforts needed to be made to improve car-bon emissions levels.Then,based on GML index model,it was found that the overall carbon emission efficiency was greatly affected by changes in technological efficiency,and had been steadily improved during the 13th Five Year Plan period.How-ever,the negative impact of extensive development was still rather obvious.Following that,correlation analysis,random forest model,and Tobit model were used to reach a conclusion that carbon emission efficiency was influenced by factors including urbanization,economic development,construction industry development,capital level of construction enterprises,energy in-tensity of the construction industry,and industrial structure,and that extensive development would bring a negative impact on carbon emission efficiency while the supply side structural reform of the construction industry would be beneficial to boosting carbon emission efficiency.Finally,countermeasures were suggested including improving the efficiency of energy consump-tion and optimizing the structure of energy consumption in terms of regions,cities,and factors.
