The Mechanism Analysis And Empirical Research Of The Firm Heterogeneity And Export Behavior

With the further study of the international trade theory,the new-new trade theory has gradually come to the stage of history,It abandons the common assumption of traditional trade theory and new trade theory:the enterprise is homogeneous.The new theory frame is constructed by re-establishing the hypothesis that the enterprise is heterogeneous and following the idea of monopolistic competition and economies of scale following the new trade theory.Initially,scholars observes a simple fact that only a part of the enterprise carry out export trade,while the rest stay in the domestic market.In this regard,foreign scholars have conducted in-depth research,Melitz as the representative,he believes that due to differences in the productivity of the enterprises,enterprises will choose different export behavior,higher productivity firms choose export,and lower productivity will not choose it.This paper tries to explore the application of heterogeneous enterprise theory in our country and multi-dimensional heterogeneity factors on export behavior,the contribution rate of heterogeneity factor,therefore,the general equilibrium analysis method,statistical analysis method,Logit model,regression analysis was applicated.This paper mainly discusses the influence of enterprise heterogeneity on export behavior.It is divided into six chapters.The first chapter is the introduction,summarizes the research background and significance of the theme,and then describes the research contents,ideas and methods,finally,the key content of this paper is summarized,and points out the possible innovation.The second chapter is literature review,which is mainly around the various factors influence export behaviors,narrating respectively from the macro and micro aspects of narrative,emphatically introduces the micro factors,such as the impact of enterprise productivity,scale,performance,innovation ability,cost,level and location of export enterprises.At the same time,the existing studies are reviewed.The third chapter is the theoretical analysis of enterprise heterogeneity and export behavior.It introduces the development course of trade in international trade,from traditional trade to new trade theory,and then to new-new trade theory.Then it focuses on the Melitz model,and finally analyzes the internal mechanism of multiple heterogeneity and its export behavior.The fourth chapter is descriptive statistics of export behavior and enterprise heterogeneity of Chinese industrial enterprises.In order to accurately describe the variables,on Chinese industrial enterprise data processing,on this basis,from three aspects,firstly,Chinese four major industrial sectors export intensity,secondly,the differences of individual heterogeneity factors between exporters and non exporters,lastly,because of the enterprise heterogeneity,the difference of export behavior.The fifth chapter is the empirical analysis of enterprise heterogeneity and export behavior.Based on the analysis of the mechanism of the third chapter,firstly,the connotation of heterogeneity is expanded,constructs the index system,and then establishes the basic model,with enterprises export delivery value as the explained variables,the basic characteristics of enterprises as the explanatory variables,and then on this basis,the other factors are added to the explanatory variables,analysis their impact for export enterprises.In addition,in order to further study the "self-selection" effect,this paper classifies the sample enterprises according to the technical level of enterprises,the probability of export status as explained variables,the Logit models are established,and the results are analyzed.Finally,combining the empirical model and the theory Shorrocks constructed,the contribution degree of each factor affecting the export behavior of enterprises is analyzed in detail.The sixth chapter is research conclusions,policy recommendations and prospects.According to the analysis of the previous research results,this paper draws several basic conclusions,and takes these as the starting point,and puts forward some policy recommendations at the two levels of government and enterprises.At the same time,the future research of enterprise heterogeneity and export behavior are prospected.Through theoretical research and empirical analysis,the paper gets the following conclusions:(1)overally,Chinese industrial enterprises do not meet the "self-selection" effect of firm heterogeneity theory,but showed the opposite situation:productivity is higher,its exports less.This also shows that Chinese industrial enterprises exist the special phenomenon:"productivity paradox",that is to say,the productivity of export enterprises is not higher than that of non export enterprises,but to some extent,export enterprises have lower productivity.(2)in different industries,low-middle technology industry,there is no "self-selection"effect,but the performance of high technology industry is similar to foreign developed economies,which consistent with the heterogeneous firm theory,namely high productivity enterprises tend to export,low productivity enterprises tend to service the domestic market.(3)from full sample,labor input,capital investment,capital and technology intensive enterprises' survival time,scale,performance,innovation ability,labor costs,subsidies intensity have a significant positive effect on the export enterprises;the productivity of the enterprise,financing costs have a significant negative impact on the export enterprises.Foreign invested enterprises,central enterprises,coastal enterprises,eastern and central enterprises are more inclined to export than domestic enterprises,local enterprises,inland enterprises and western enterprises.(4)the contribution rate of enterprise productivity to its export behavior is the highest,the innovation ability,level,location is second,performance,subsidy and cost contribution rate is smaller,and the contribution rate of enterprise scale is the smallest.The possible innovations of this paper are as follows:(1)the expansion of heterogeneous variables affecting firm export;(2)the contribution rate of firm heterogeneity to firm export is quantified by the regression decomposition method.
