Research On Total Factor Carbon Emission Efficiency Of Transportation Industry In Yangtze River Economic Belt

As one of the regions with the strongest comprehensive strength and most important strategic support in China,the Yangtze River Economic Belt develops under principles of ecological priority and green development.With the formulation and implementation of relevant strategic policies,construction of the transportation infrastructures in Yangtze River Economic Belt has achieved fruitful results,the network scale has been continuously expanded,and energy consumption and carbon emissions have grown rapidly.Requirements of continuous and consistent social and economic development on transportation industry indicate that the transportation infrastructures,equipment,service demand,energy consumption and carbon emissions will continue to maintain rapid growth in a certain period of time.Following this trend,the contradiction between transportation development and resources and environment constraints in Yangtze River Economic Belt will become more intense.The total amount of carbon emissions in transportation industry will not reach its peak in 2030.Therefore,to support and ensure achieving goal of reaching China’s carbon emission peak in 2030,it has become an inevitable choice to implement more powerful management measures and more efficient technical means to reduce carbon emissions and improve carbon emission efficiency.Proceeding from the perspective of total factor,this thesis systematically studies the measurement and influencing factors of carbon emission efficiency,and proposes countermeasures and suggestions to reduce carbon emissions and improve the total factor carbon emission efficiency.It is of great theoretical and practical significance.The main contents and conclusions are as follows:(1)This thesis analyzes the general situation of the transportation industry in Yangtze River Economic Belt,uses the “top-down” method to measure carbon emissions,and analyzes the time distribution characteristics and regional differences.The main conclusions are: The transportation industry develops fastly and at the cost of energy and environment;Total carbon emissions continue to increase from 2005 to 2016,and carbon emissions per unit GDP and carbon emissions per unit conversion turnover are generally reduced;There are significant regional differences in total carbon emissions,carbon emissions per unit GDP and carbon emissions per unit conversion turnover in Yangtze River Economic Belt.(2)This thesis defines the concept of total factor carbon emission efficiency of transportation industry,measures its value and analyzes its evolution characteristics based on the Directional SBM-GML index model,studies its spatial autocorrelation characteristics by Moran’s I.The main conclusions are: The total factor carbon emission efficiency of the transportation industry refers to the largest conversion turnover,most gross domestic product and minimum carbon emissions that can be obtained under fixed labor,capital and energy input with certain technical conditions;From 2005 to 2016,the value of total factor carbon emission efficiency is at a low level and the mean value is only 0.7346.Technological progress is a major determinant in improving total factor carbon emissions efficiency;the correlation between provinces in Yangtze River Economic Belt is weakly negative.Siphon effect and lack of linkage has been presented in the development of transportation industry in provinces of Yangtze River Economic Belt.(3)This thesis applies path analysis to study the influencing factors of total factor carbon emission efficiency.The main conclusions are: Total factor carbon emission efficiency is affected by internal and external influencing factors of transportation industry,and independence and correlation between different factors coexist;According to the absolute value,the order of comprehensive effect of each factor on total factor carbon emission efficiency is: Industrial Structure>Per Capita GDP>Energy Structure>Transportation Structure>Energy Intensity >Transportation Intensity.(4)Considering the rights of the transportation industry,this thesis studies the dynamic impact of transportation structure and energy intensity on total factor carbon emission efficiency.The main conclusions are: Overall,transportation structure optimization and energy intensity reduction have positive effect on the improvement of total factor carbon emission efficiency,and the effect of transportation structure is greater than energy intensity.However,the existence of Energy Rebound Effects has caused the role of energy intensity underestimated.(5)On the basis of the above research,this thesis proposes countermeasures and suggestions to improve the total factor carbon emission efficiency.These mainly include: Optimizing industrial structure and transforming economic development mode;optimizing transportation structure and reducing transportation intensity;optimizing energy structure and reducing energy intensity;accelerating technological progress;implementing regional differentiation policies and strengthening regional linkage development.
