A Study On The Dual Margin Of China’s Export Growth Along The Silk Road Economic Belt And Its Influencing Factors

With the continuous development of the Silk Road economic belt,China and the Silk Road economic belt along the country’s trade cooperation has deepened,at the same time,China is also one of the Silk Road largest trading partner,the largest export markets.So what is the source of China’s export growth along the Silk Road economic belt?What are the influencing factors?In this paper,we use the binary marginal decomposition method of export growth to analyze the contribution of China’s Silk Road economic belt on the basis of the degree of contribution of export growth(the rate of export growth of old products)and the expansion margin(new product export growth rate)The country’s export growth source,and further use the measurement model to test China’s Silk Road economic belt along the country’s export growth factors.This paper first reviews the relevant literature on the export of binary margins and explains the basic concepts and measures.Secondly,through the analysis of the overall scale of exports and the structure of commodities,this paper depicts China’s export trade on the border of the Silk Road economy status quo.On the basis of the above,this paper uses the micro-level data to separate the export trade flows from the countries along the Silk Road economic zone from the two aspects of product category and product value.The results show that China The expansion of the export trade of the Silk Road economic belt was mainly carried out along the margin of integration,and the expansion of export trade to small countries(Uzbekistan,Tajikistan and Georgia)was mainly achieved along the expansion margin;again,Silk Road economic belt along the national export dual marginal status and characteristics of the use of China from 2001 to 2014 on the Silk Road economic belt along the country’s export trade data,select the economic scale,multilateral trade resistance,distance,the organization of virtual Variables,trade freedom and other variables to build an intensive margin and the expansion of the marginal model,the binary marginal factors of the empirical analysis and testing.The empirical results show that the impact of the economic development level of the importing country on the margin of export and the marginal margin of export is more significant and positive,and the influence of multilateral trade resistance on the marginal margin is also positive.Fixed trade costs have a significant negative impact on the binary margin,and the decline in export fixed costs is more conducive to the expansion of the trade margin.Finally,based on the theoretical analysis and empirical research,this paper puts forward the corresponding policy suggestions on the status quo of China’s export trade along the Silk Road economic belt:speed up the negotiation process with the countries along the Silk Road economic zone,And jointly promote the "interconnection" of the infrastructure construction process;gradually reduce the cost of trade,effectively promote the export margin and the expansion of the marginal growth of the dual growth.
