长江经济带交通业节能减排效率与绿色经济耦合关系研究
Coupling Relationship between Energy Conservation and Emission Reduction Efficiency of Transportation Industry and Green Economy in the Yangtze River Economic Belt
摘要
Abstract
To explore the coupling coordination relationship between energy conservation and emission reduction efficiency of the transportation industry and green economy,this paper took 11 provinces(cities)in the Yangtze River Economic Belt as the research object,and constructed the evaluation index system of energy conservation and emission reduction efficiency of the transportation industry and green economy.Meanwhile,the super efficiency SBM model and entropy method were adopted to measure the energy conservation and emission reduction efficiency of the transportation industry and the development level of the green economy respectively.Then,the coupling coordination degree model was employed to explore the coupling coordination of the two,with the kernel density estimation method and Tobit model utilized to analyze the spatiotemporal evolution characteristics and influencing factors.The results show that from 2013 to 2022,the energy conservation and emission reduction efficiency of the transportation industry in the Yangtze River Economic Belt shows a trend of first decreasing and then increasing,while the development level of the green economy shows an upward trend.The coupling coordination degree of the two continues to improve in time sequence:Spatially,the lower reaches of the Yangtze River are in the lead,the middle reaches are in the middle,and the upper reaches are relatively backward.Scientific and technological innovation,opening up,and industrial structure play a role in improving the coupling coordination degree of this region,energy consumption negatively correlates with it,and environmental regulations have no significant influence on it.Finally,targeted suggestions were proposed based on the research results.关键词
