Study On The Impact Of Firm Multiple Heterogeneity On Firm Export Behavior

With the emergence of Heterogeneous Firm Trade Theory,the perspective of study on international trade has shifted from the macro-level to the micro-level.And the relationship between firm heterogeneity and firm export behavior has become the new research trends of the international trade.Some scholars at home and abroad have found that single productivity can't be used to explain the whole of firm export behavior.Based on it and combined with our unique economic environment,the paper extends firm heterogeneity form the single productivity to the multiple heterogeneity which includes productivity,enterprise scale,capital intensity,innovation ability,financing ability,human capital,enterprise brand and enterprise age to explore its impact on firm export behavior.The paper discusses the impact of firm multiple heterogeneity on its export behavior from both theoretical and empirical perspectives based on the analysis framework of Heterogeneous Firm Trade Theory.Firstly,the paper summarizes the literature at home and abroad and makes a review.Secondly,the paper defines the related concepts and examines the influence mechanism of firm multiple heterogeneity on firm export behavior by means of the theoretical analysis framework of Melitz(2003)and Bernard and Jensen(2001,2004).Thirdly,Combined with Chinese manufacturing firm-level data from 2005 to 2007,the paper measures the related indexes and illustrates the existence of firm multiple heterogeneity by means of statistical analysis method.Fourthly,the paper analyses the impact of firm multiple heterogeneity on its export behavior by means of metrological analysis which includes Porbit random effects model,Logit random effects model,fixed effects model and panel quantification model.Finally,the author puts forward some suggestions based on the research results.The conclusions of this paper are as follows:First,on the firm heterogeneity and export participation:(1)enterprise productivity,enterprise scale,enterprise innovation ability,enterprise financing ability,enterprise human capital,enterprise brand and enterprise age have significant positive impact on firm export participation,while enterprise capital intensity has a significant negative impact on firm export participation.(2)Under different dimension groups,enterprise productivity,enterprise innovation ability,enterprise age have a positive effect on firm export participation,and enterprise capital intensity has a strong negative effect on firm export participation.While there are significant industry differences,ownership structural difference and region difference about the impact of other heterogeneous variables on export participation.Second,on the firm multiple heterogeneity and its export scale:(1)enterprise productivity,enterprise scale,enterprise innovation ability,enterprise financing capacity,enterprise human capital,enterprise brand and enterprise age have a significant positive impact on its export scale,while capital intensity has a significant negative impact on the firm export scale.(2)In addition to financing capacity,capital intensity and human capital,the positive effect of firm's other heterogeneous variables on its export scale enhances with the increase of firm export-level.(3)Under the different dimension group,the positive effect of enterprise productivity and enterprise scale on firm export scale is robust.The influence of other heterogeneous variables on the scale of enterprise export has significant industry differences,ownership difference and regional difference.
