A Study On The Impact Of Embedding In Global Value Chains On China’s Trade-Embodied CO₂ Emissions

Using data obtained from the World Input-Output Database,this paper estimates China’s overall and subsector trade-embodied carbon dioxide emissions in global value chains（GVCs）from 2000 to 2014 and examines the drivers of China’s CO₂ emission changes through chaining structural decomposition analysis（Chaining SDA）.Our findings suggest that China’s overall trade-embodied CO₂ emissions in GVCs increased by 198.18%from 2000 to2014.China’s industrial CO₂ emissions in GVCs are mainly concentrated in knowledge-intensive manufacturing industries,labor-intensive service industries and public service industries.The chaining SDA results show that China’s domestic consumption expansion is the biggest reason for the rapid growth in China’s overall CO₂ emissions,while foreign consumption demand fluctuates greatly due to the impact of the international economic situation.The main factor that promotes China’s CO₂ emission reduction is the reduction of carbon emission intensity,but the weakening of its emission reduction effect indicates the increasing difficulty of technological emission reduction.In addition,consumption preferences have reduced CO₂ emissions in industries such as knowledge-intensive services to a certain extent.This paper mainly focuses on the CO₂ emission effects of the GVCs.The chaining SDA results show that participation in the division of labor in GVCs has greatly aggravated China’s overall trade-embodied CO₂ emissions,but its positive impact has gradually decreased in recent years,and in some years it has produced certain reduction to the overall CO₂ emissions.After distinguishing the way of embedding in GVCs,it is found that the final product effect is the main reason and path for the sharp increase in CO₂ emissions caused by China’s embedding in GVCs,and the CO₂ emission reduction effect of GVCs is through the path of intermediate product.After further subdividing the industries,it is concluded that the division of labor in GVCs has a greater impact on the manufacturing industry than on the service industry.The GVCs has exacerbated the CO₂ emissions of China’s capital-intensive manufacturing industries,capital-intensive service industries,knowledge-intensive manufacturing industries,and public service industries through the intermediate product effect and the final product effect.In addition,the GVCs also reduce the CO₂emissions of labor-intensive service industries,labor-intensive manufacturing industries,and primary industries through the path of intermediate goods.Finally,comparing the industrial carbon emission effects of both intermediate products and final products,it is concluded that labor-intensive manufacturing industries,labor-intensive service industries,and capital-intensive service industries should be embedded in the GVCs division of labor in the way of intermediate products,while the knowledge-intensive manufacturing industries,knowledge-intensive service industries,and public service industries in the way of final products,thus to promote China’s overall CO₂ emission reduction.The emission reduction in the service industry should also attract attention.
