Comparative Study Of BRIC's Export Trade And Global Value Chain Position Under Value-added Trade Theory

The continuous development of economic globalization makes commodity production break through national boundaries and completed by division of labor cooperation by different countries around the world.Traditional export measurement method calculates the final product value and ignores the imports of intermediate goods in the process of production and all kinds of foreign value,leading to an overestimation of a country's total export.Value-added trade theory makes measuring a country's "real" trade status and position possible.BRIC,as important representatives in emerging economies,play an increasingly important role in the world economy.In recent years,facing the economic downturn and internal structure adjustment,BRIC focus on discovering new economic growth point,and promoting north-south cooperation through south-south cooperation,to provide constructive help to promote world economic recovery,so it is important to study BRIC's economic growth model and its comparison with the rest of the world.This paper,by using kpww method and WIOD from 2000 to 2011 provided by OECD,calculates the trade added value and its proportion of total export for altogether 14 countries,including BRIC,and further calculates and analyzes foreign value-added proportion of 35 segment industries.Then calculate and compare Global Value Chain participation and position of 35 segment industries of 14 countries by using former data and Koopman's index.The result shows that the foreign value-added proportion of low technology industry of BRIC and new drill countries,which are called emerging economies,is slightly lower than developed countries,while that of high technology is much higher than developed countries.The dependence on foreign added value is the reason why emerging economies can't resist the support from developed countries in high-tech industries.Generally,Global Value C hain participation of emerging countries is higher than developed countries.But after analyzing the inner structure of its participation we can know that emerging economies mainly rely on the comparative advantages of labor and resources to occupy the high-end of GVC in low and medium technology ind ustries.Developed countries still dominate the high-end of GVC in high technology industries by controlling R&D department.Facing the "real" trade status under value-added trade theory,BRIC,especially China,should invest more in research and technology,fully participate in the world tide of electronic information,use various financial ways to support innovation enterprise,improve labor quality to step into global market under new conditions,implement the export trade industry restructuring and upgrading to change from "low-end embed" into "high-end occupation".
