The Enterprise Heterogeneity, Technical Innovation And Product Export

International trade theory develops from the original classical tradedevelopment to the new classical trade, And to the new trade theory, Until thepresent trade theory (heterogeneous firm trade theory) which makes reasonableexplanation to the reasons、 ways and the distribution of interests from themicroscopic enterprise. Foreign scholars have studied the applicability of this theoryin the developed countries in both theoretical and empirical. They come toconclusion that the enterprises which have higher productivity exports more; Thelow productivity of the enterprise serve the domestic market; the lower productivityof the enterprises are forced to withdraw from the market. Although china is adeveloping country, it has become the second largest economy and the biggestexporter in the world in2010，so its international market position and role can not beignored. In our export products，Textile industry is always one beautiful branch,which has made great contribution to the economic development. The domesticscholars have studied the heterogeneous firm trade theory’s applicability in China。But they generally choose a large range of manufacturing industry, not confined to asingle industry, especially in the textile industry. In order to maintain and promotethe development of China’s textile industry, improving the internationalcompetitiveness of China Textile Enterprises, this paper does research on the specificrelation of export and productivity based on the heterogeneity of enterprises tradetheory on textile industry.With the progress and promotion of science and technology，people’s productionand life has changed a lot. Although the textile industry has been the traditionallabor-intensive industries, the development of any industry is inseparable fromtechnological innovation in information technology era. High technology enterpriseshave high productivity, low cost and more export competitive advantage. With therising raw materials and labor costs, to maintain textile industry advantage we must seek production process improvement and technology innovation application.This paper elaborates the on development of the international trade theories andcombines with the theoretical and empirical research of domestic and foreignscholars, which introduces the classical model on the basis of the heterogeneous firmtrade theory and the impact of technology innovation on export model detailedly.Then we analyze the influence of the heterogeneity and the technological innovationof textile industry to export using the1993-2008data empirically. In the study, wecalculate the total factor productivity of textile industry by setting the KeBu-Douglasproduction function firstly, represent technological innovation and export with patentapplication quantity and the growth rate of exports for a stationary test. Then weinspect the long-term relationships of the three variables through cointegrationanalysis. They all have positive correlation relationship with the export, promoteexport growth and make a more comprehensive explanation for export together.Finally, based on study conclusion, we put forward some specific suggestions topromote our country textile enterprises export growth and productivity.However, restricted by study and research conditions and my ability, the articlehas many deficiencies.
