生产率与中国高技术企业出口相关性研究——基于异质企业贸易理论的视角

Research on Correlation between Productivity and China's High-tech Enterprises' Export ——From the Perspective of Heterogeneous Enterprise Trade Theory

高技术产业出口近年来迅速增加,容易使人得出我国贸易结构升级,国际竞争力加强的结论。我国2008年近两万家高技术企业的微观数据分析表明企业出口与生产率呈现负相关关系,这一现象不符合异质企业贸易理论。研究发现企业性质、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其违反异质企业贸易理论的根本原因。

The rapid increase in export of high-tech industries in recent years makes people easily draw the conclusion that China＇s trade structure has been upgraded and its international competitiveness has been strengthened.However,based on the micro data analysis of nearly 20,000 high-tech enterprises in China in 2008,it is found that high-tech enterprise export has a negative correlation with productivity,which is not consistent with the heterogeneous enterprise trade theory.The research found that the nature of an enterprise and the ratio of capital and labor are the major factors influencing export.The large number of processing trade high-tech enterprises is the fundamental reason for its inconsistence with the heterogeneous enterprise trade theory.
