The Binary Marginal Analysis Of Chinese Exports

China experiences great economic development since the policy of reform and opening up,meanwhile our economic and trade exchanges with other countries increases rapidly:export products' category,total amount of number and value show a rapid growth trend.However,there are some factors hindering the development of our export trade market,that is:export products' profit margins are shrinking along with the rising labor costs;China's export trade market is rather fragile when facing numerous external shocks.Based on the model of enterprise heterogeneity,gathering trade data between China and 11 main cooperation partners(with China)from 2005 to 2015,this essay uses the heterogeneity of multilateral asymmetric model built by Chaney(2008),and then,uses Eviews software to calculate the stylized facts of the dual margin of China export growth as well as its influencing factor from bilateral and multilateral aspects.The innovation lies in:first,innovation of data processing.This paper uses product level trade data,rather than the traditional enterprise level data,thus effectively avoid the falsely decrease of the extensive trade margin since export enterprise usually export more than one kind of product.Second,innovation of research angle.This paper analyses China export growth structure as well as its influential factors.Third,innovation of the research method.This paper define the dual margin of China export growth more specifically,including export products which has already exit export market,meanwhile,analyses more comprehensively of the structure of China export trade from three aspects:export products' category,total amount of number and value.Through the collection and sorting of data,this paper comes into conclusion:in ten years,China export growth is mainly relied on intensive margin rather than extensive margin no matter from bilateral level or multilateral level.When analyzing the influential factors of export trade,the main conclusions are:economies of scale,productivity and multilateral resistance show promoting effect on exports whether intensive marginal or extensive marginal,which is expected;however,the cost of the fixed trade shows positive effect,which is unexpected.Therefore,it is important to take efforts to develop new export products and endeavor new export markets maintain the stability of China foreign trade market.Thus,it requires export enterprise to further enhance productivity,our country to embrace international export.In order to maintain China export trade market stability,our countries should pay more attention to develop new trade relationship with other counties as well as maintaining old trade partners.
