Value Added And Carbon Emission Research Of China’s Logistics Industry Based On Input-Output Perspective

Today,curbing climate warming and reducing carbon emissions have become main consensuses among the international community.Under the tide of economic globalization,China has been deeply involved into the Global Value Chain(GVC).The logistics industry has also attained rapid development by participating in GVC activities,with higher and higher value-added output.However,as a major energy consumer,the contradiction caused by high energy consumption,high carbon emissions and green development conception is emerging.Meanwhile,the embodied carbon caused by trade activities has a great negative impact on carbon emission reduction policy,making the policy have little effect.Therefore,it is of great practical significance for China’s logistics industry to achieve energy conservation and emission reduction and high-quality development with a comprehensive understanding of its development picture and industrial competitiveness,a grasp of its geographical distribution differences of embodied carbon,and an exploration of its carbon emissions influencing factors’ effects.Based on the above background and problems,and on the bases of summarizing relevant literature on value-added and carbon emissions researches about logistics industry.Firstly,this paper uses the input-output model to study the value-added effect for China’s logistics industry,and analyzes its development circumstances and industrial advantages.Secondly,it calculates and decomposes carbon emissions through the GVC,and analyzes geographical distribution differences of embodied carbon.Finally,it constructs IO-SDA model to study the influencing factors of carbon emissions,and analyzes different effects of each factor on carbon emissions.The study shows that,(1)The breadth and depth of participation of China’s logistics industry in the GVC are obvious,and it has a stronger competitiveness.The total amount of value-added is growing rapidly,and the value-added export is also growing.Although its GVC forward and backward participation do not change obviously,they are more remarkable than others.(2)There are obvious differences in the geographical distribution of import and export embodied carbon for China’s logistics industry.Although both import and export embodied carbon have increased,the export embodied carbon is more.Import embodied carbon is more distributed in the B&R district,while export embodied carbon is more distributed in the nonB&R district,and their major associated countries also changed.In addition,import and export embodied carbon are nearly equivalent in the B&R district for China’s logistics industry,which results in a two-way environmental cost offset.(3)The carbon emission intensity factor has a stronger restraining effect on the growth of carbon emissions.Although the intermediate input technology factor promotes carbon emissions growth,its influences are limited,the final demand factor is the biggest factor of carbon emissions growth.
