Research On The Impact Of Global Value Chain Participation On China's Export Trade Embodied Carbon Emissions

Economic globalization has made the form of international division of labor developed from inter-departmental specialization to intra-departmental specialization,and the global value chain has become a significant feature of the development of international trade.China actively integrates into the division of labor in the global value chain,gaining economic benefits in this process,and also producing a large amount of carbon pollution.Therefore,it is necessary to study the impact of global value chain participation on the embodied carbon of China’s export trade in the context of carbon emission reduction.In view of this,this paper calculates China’s global value chain participation and export trade embodied carbon,and uses a panel measurement model to conduct an empirical study on the export embodied carbon emission effect of global value chain participation.First,based on the 2000-2014 world input-output table,decomposing the value added of China’s exports under the framework of total trade accounting,and China’s global value chain participation indicators are measured.The results show that China’s value chain participation has increased during the inspection period.Backward participation is generally higher than forward participation,and global value chain participation in manufacturing and energy industries is higher than other industries.Secondly,on the basis of the value-added decomposition formula,the carbon emission factor is introduced to calculate the embodied carbon emission of export trade.The results show that the embodied carbon emissions of China’s export trade continue to increase during the inspection period.Export trade embodied carbon is divided into exporting countries’ carbon emissions,importing countries’ carbon emissions and third countries’ carbon emissions.It is found that most of China’s export trade embodied carbon comes from the exporting country’s own carbon emissions,accounting for 90% of the carbon emissions,while importing countries and third countries produce trade embodied carbon emissions account for only less than 10%,indicating that China bears most of the carbon emissions when it conducts bilateral trade with other countries,which are generated by the country and remain in the country.Finally,a panel measurement model is constructed to study the relationship between the export trade embodied carbon emissions and global value chain participation.There is an inverted "U"-shaped relationship between the export trade embodied carbon and China’s participation in the global value chain,the relationship between the two is nonlinear.The panel threshold model is used to further study the specific impact mechanism under the nonlinear relationship,and it is concluded that China participates in the global value chain.In the initial stage,it has an increasing effect on the embodied carbon of export trade.When the degree of participation crosses a certain threshold,the degree of participation in the global value chain begins to weaken the embodied carbon emissions of trade,and with the deepening of the value chain participation,the effect of weakening becomes more and more.The results of panel threshold analysis of China’s different industries indicate that the embodied carbon content of China’s heavy manufacturing,energy,and other industries’ export trade will continue to rise with the increase in participation in global value chains,and lighter manufacturing and service exports.Embodied carbon gradually decreases with increasing participation in global value chains.Based on the above empirical results,relevant suggestions and countermeasures were put forward.China should strengthen local innovation and improve the low-carbon level of production methods.At the same time,it pays attention to quality when participating in the global value chain,optimizes the export structure,and strives to climb up the value chain.
