| In retrospect,it takes a long time for the academe to study the trade pollution problems.Recently,along with the deepening threat of global warming and the ecological environment deterioration in developing countries,more and more government agencies and ordinary people have begun to focus on this.As an important global economy participant,China’s trade pollution has gotten world’s attention.So,we are curious about that: does China’s integration into the global value chains benefit or harm to domestic environmental protection? How much cost do we pay for obtaining today’s great status?During this article,we first combed the literature to find a breakthrough: that is introducing the trade benefits into trade environmental analysis.Then we replaced the single indicator of environmental impact with the environmental costs,which means embodied carbon emissions per value added,in order to measure China’s trade pollution.According to this basic idea,we integrated the theory of global value chain,trade in value added as well as the participation of China in global production to explore the links between trade interests and trade pollution problems as support for subsequent model.Next,we introduced input-output model as the main empirical methods which based on China’s national input-output table and the world satellite environmental accounts(published by World Input Output Database).Select the CO2 emission embodied in manufacturing export and value added as the representative of pollution and profit to research the partial balance of China’s export.Compared with the previous study,we not only introduced trade profit,but also built different models which based on their performance in domestic production process to improve the accuracy,when facing the intermediate with different sources.After calculations,we concluded that: assimilating into the global value chain is conducive to China’s environmental protection.Specifically,although the CO2 emissions embodied in export are totally rising,the indicator of embodied carbon emissions per value added is decline in view of our great expand in trade scale owing to China’s accession to WTO.Our environmental costs are declining in integrating process.In the future,we should deepen opening-door policy.On the one hand,help domestic enterprises to improve its position in the value chain and build their own value chain,on the other hand,encourage foreign enterprises to invest in high-tech,clean industry,and increase domestic environmental regulations implementation and supervision. |
