A Comparative Study On The Trade Profits And CO2 Emissions Of China's Regions In Participating In The Global

In recent years,The contradiction between China's economic development and environmental protection has become increasingly prominent due to the deepening of China's participation in the global value chain(GVC).In this process,the performance and status of China's regional in the global value chain vary widely,not only because of China's vast,uneven of Regional endowments and development levels,but also in closely related with the different trade patterns or the way of participation in the GVC.In order to make China out of the dilemma of "economic development" and "environmental protection",on the one hand to alleviate the pressure of the international community to reduce emissions and achieve low-carbon sustainable development,on the other hand to maintain economic and rapid development to promote our country in the global value chain,It is necessary to compare the profits and carbon emissions costs of regions in China in participation in global value chain.Based on this background,this paper builds a global input-output model embedded in China's sub-region and links the sub-regions in China with other countries in the world industry and trade on the basis of WIOD and China's regional input-output table,to calculate value added and carbon emissions from the regional perspective.The main content of this paper is organized as follows:Chapters 1 and 2 mainly reveal the starting point and research purpose of this paper from the background of reality and the theoretical background.The third chapter specifically introduces the construction of the model;on the basis of this,the fourth and fifth chapter measures the value added and carbon emissions costs in for participation in global trade-induced.Finally,it summarizes and proposes relevant policy recommendations accordingly.Through the above total level of analysis,this paper finds that:Firstly,there is a big gradient difference in the export of value added and carbon emissions in China China's coastal areas is deeply integrated into the global value chain,but it also caused a lot of carbon pollution while supporting China's export interests.Second,the ways in which all regions participate in global value chains vary.Coastal areas participate in GVCs mainly through direct exports,while inland areas indirectly participate in GVCs through the provision of intermediaries in coastal areas.Finally,the share of exports to the United States and Japan,while decreasing in value over time,still accounts for a high share of the value-added and carbon-export destinations(outflows).The majority of the countries that eventually make carbon emissions flow to various regions of China,mainly the coastal areas,with very few flowing into the United States and Japan.Judging from the above two points of comparison,our country has achieved an added value output in international trade,but it has left carbon emissions at home.WWZ decomposition is further carried out in order to gain an in-depth understanding of the source,composition,and path of value added and implied carbon in exports at the sectoral level.The conclusion shows that the domestic value-added content(DVA)is the main source of export value added.From the time trend,the proportion of DVA generally shows a downward trend;on the contrary,the proportion of foreign value added(FVA)has slightly increased.The breakdown of carbon emissions is similar to that of added value.However,in terms of value added or carbon emissions,the share of final product exports in the vast majority of domestic value added(carbon emissions)and foreign value added(carbon emissions).This shows that at this stage of our country,the low-end embedded global value chain is still in the mode of production with the final export of processing and assembly exports.Further decomposition shows that the path of carbon emission shifting is more complicated and more subtle.Based on the above research,this paper argues that China's foreign trade structure should continuously optimize the trade structure of intermediate products,and at the same time change the export mode based on the existing processing trade so as to climb up the upper reaches of the global value chain.Internally,there is a need to focus on the integration of resources between regions,let the coastal areas drive the central and western regions,thereby reducing the gradient difference between regions and effectively integrating the domestic value chain.
