中国高技术企业出口影响因素分析——基于异质企业贸易理论的视角

笔者采用我国2008年近2万家高技术企业的微观数据,运用LS和probit两种计量模型进行实证研究发现,我国高技术企业的出口并没有生产率方面的优势,出口企业的生产率低于非出口企业.企业性质、企业资本劳动比才是出口的主要影响因素.高技术产业中加工贸易企业的大量存在是造成这一现象的主要原因.

An Analysis of the Factors Influencing the Export of China's High-tech Firms——A Review from the Perspective of Heterogeneous Firm Trade Theory

The rapid increase in the export of high-tech products in recent years is very impressive.Using the data of 20,000 firms in China’s high-tech industry in 2008,applying LS and Probit models,the authors made an empirical study.The findings show that the export of China’s high-tech firms did not have advantage in productivity.The productivity of export firms is lower than that of non-export firms.Using four methods of measuring productivity,the authors got the same result,which shows the conclusion is reliable.The research also found that the nature of firms and the ratio of capital to labor are the major factors influencing export.The authors explored the underlying reasons for the situation and found the large number of processing firms in the high-tech industry is the main reason for this phenomenon.
