An Analysis Of The Ternary Margin Of Export Growth From The Perspective Of Enterprise Heterogeneity

In recent years,more and more scholars have conducted relevant researches on a country's export growth from the perspective of three-dimension margin.As far as China is concerned,export trade has contributed greatly to the growth of China's economy.But growth slowed after the 2008 crisis,and China's traditional export advantage of cheap labor is fading,with workers' costs rising as land prices rise.These factors have reduced the international competitiveness of our export products.Therefore,the factors affecting export growth and how to ensure the stable export growth are the focus of this paper.This paper,by using 2000-2006 the customs data for Chinese enterprises as a whole,and the annual export dynamic characteristics analysis and reference Hummels and Klenow decomposition method(2005),all the enterprises for reference,to get each of N national enterprise three yuan in the marginal(extended marginal,marginal quantity and marginal price),and then according to the result of decomposition analysis way of the Chinese enterprises to export growth.Then will the customs database database to merge with industrial enterprises panel data,combined with BvD global macro database and CEPII database,from the perspective of enterprise micro level,research the influence factors of export growth,using the new-new trade theory as the theoretical basis of this article,combined with the gravity model,the main analysis enterprise characteristic variables with the national characteristics of our country enterprise three yuan marginal effect of export growth.At last,we explore the mechanism of export growth from quantity margin to expansion margin,and find the effective way of export structure optimization.Through theoretical research and empirical analysis,the following conclusions are drawn:(1)China's export growth is mainly achieved through intensive marginal,and the quantity marginal in intensive marginal is the most important driving force for export growth.(2)In terms of national characteristics,the market size of the country of destination is directly proportional to the expansion margin and quantity margin of export growth,and inversely proportional to the price margin of enterprise export growth;The distance from China to the country of destination,that is,the variable trade cost of enterprise export has restrained the growth of enterprise export.The number of enterprises exported to the country of destination,that is,the number of competitors of the exporting enterprise has a inhibiting effect on the expansion margin of the enterprise,and the price margin of export growth is inversely proportional to the change,while the quantity margin of export growth is positi vely proportional to the change.(3)In terms of enterprise heterogeneity,total factor productivity and expansion margin of enterprise export growth,price margin and quantity margin show u-shaped curve changes;The variety innovation of an enterprise has a significant positive effect on the expansion marginal and price marginal of the enterprise,while the quantity marginal is an inhibitory effect on the enterprise.The export scale of enterprise and the marginal impact of enterprise expansion are positive,and the marginal intensity of enterprise is inversely proportional.The ratio of capital labor to price margin to quantity margin changes in direct proportion,but it restrains the expansion margin of export growth.In terms of the financing constraints of enterprises,the improvement of the financing ability of enterprises is conducive to the expansion margin of the export growth of enterprises,which has a significant negative impact on the intensive margin of China's export growth.For the size of the enterprise,the larger the size of the enterprise,the faster the export growth.That is to say,the marginal triad of export growth and the size of enterprises are all proportional changes.As for the dummy variable of impact(whether to join WTO or not),the conclusion is drawn that impact variable promotes the extension marginal and quantity marginal,while inhibits the price marginal.The possible innovation points of this paper:(1)to study the ternary marginal of export growth from the perspective of micro enterprises;(2)the three marginal factors influencing the export growth of enterprises are investigated by combining the national characteristics and enterprise characteristics,and expansion of heterogeneity variables affecting enterprise export growth.
