多元视角“生产率悖论”研究述评

Literature Review on Multi-Perspective Studies of the “Productivity Paradox”

Melitz(2003)构建了异质性企业贸易模型,得出出口企业的生产率高于内销企业的生产率。在那之后,国内外学者纷纷用各国的工业企业数据进行实证检验。当用中国工业企业数据进行检验时,发现我国出口企业的生产率比内销企业生产率还低,这与异质性企业贸易理论的结论相违背,学者们称之为"生产率悖论"。针对中国出口企业"生产率悖论",国内学者从不同视角做出了解释,文章回顾了近年来学者们提出的一些主流观点并加以述评。

Melitz（2003） has built a model of heterogeneous-firm trade theory which comes to the conclusion that export enterprise＇ s productivity is higher than domestic enterprise＇ s. Since then, scholars, home and abroad, have tested the conclusion with different country＇s in- dustry firm data. However,when using China＇ s industry firm data,domestic scholars discovered that the export enterprise＇ s productivity of our country is lower than domestic enterprise＇ s which is contrary to the conclusion of heterogeneous-firm trade theory, which, hence, is called ＂productivity paradox＂. This issue has been investigated from various perspectives, which is summarized comprehensively in this paper with further comments.
