中国制造业出口企业存在生产率悖论吗——基于企业出口状态转换的视角

Is There Productivity Paradox in China's Manufacturing Export Firms:Basing on the Perspective of Firm's Export Status Transition

基于出口状态转换的视角,按照存续期内的出口状态将企业划分为持续出口、新出口、退出出口、间断性出口和始终不出口等五种类型,在此基础上考察出口与企业生产率的关系。研究结果否定了出口企业存在生产率悖论:任何类型出口企业生产率都要高于始终不出口企业;持续出口企业具有显著自选择和干中学效应,间断性出口企业效应不显著。

Basing on the perspective of firm＇ s export status transition,according to their export status within a period,this paper divides the firms into five categories,firms that export all the time,firms that newly enter export market,firms that quit from export market,firms that export randomly and firms that never export,on which relationship between export and firm ＇s productivity is investigated. The result indicates that there doesn＇ t exist productivity paradox in China＇ s export,which means that all kind of export firms have higher productivity than firms that never export,firms that always export have significant self-selection and learning- by- doing effect in the export market while the effect is not significant for firms that export randomly.
