The Foreign Trade Costs And Dual Margin Of Export Growth In China

The new-new trade theory provides a theoretical basis for studying the micro structure of trade growth,by constructing the heterogeneity model,the theory decomposes the growth of the trade into the intensive margin and the extensive margin,and clarifies the influence mechanism of the trade cost on the dual marginal.Behind the rapid development,there are potential crises in China’s export growth,in order to better analyze China’s export growth model,we should take deep analysis from the micro perspective.This paper is based on the new-new trade theory and use the trade data of HS-6 digits in China and 10 major countries(regions)from 2001 to 2015 to analyze.Firstly,the paper describes the characteristics of China’s export growth,the scale,regional,structural and cost characteristics and finds that China’s export growth is extremely fragile,export growth slowed down,export growth structure is unreasonable,foreign trade costs are still in pressure.And then to calculate China’s export growth of the dual margin and trade costs and finds that in China’s export growth,the intensive margin plays an absolutely dominant role,and the contribution of the extensive margin is smaller both in the export volume level and the export category level.China’s foreign trade costs as a whole showed a downward trend,but in the context of the global economic recovery is weak,there will be ups and downs;Thirdly,to better measure the effect of trade costs on the dual margin,this paper analyzes the various constituent elements of trade cost,the results show that the influence of different factors on the dual margin is different,and the influence of the same factors on the extensive margin and the intensive margin is different,fixed trade costs mainly play a role in extensive margins and variable trade costs are primarily influence the intensive margin.Finally,according to the above analysis,this paper proposes the policy recommendations to promote trade cost reduction and export growth,such as promoting trade liberalization,expand the international market and improving product technical content.
