出口贸易技术溢出与企业生产率——基于中国制造业企业微观面板数据

摘要

Using the balance panel data of 2006-2008 from China manufacturing enterprises,the relation between export spillovers and enterprises productivity is studied.The empirical results show that horizontal linkage export spillover and backward linkages export spillovers for enterprise productivity have significant positive effect.We further found that domestic enterprises are the main source of export spillovers.For foreign-funded enterprises,its horizontal linkage export spillover is less,and its backward linkages export spillovers show a negative effect.The strong competitiveness,the buyer power,and the strict protection of intellectual property are the possible explanation of this phenomenon.%利用2006年—2008年中国制造业企业的平衡面板数据集,研究了出口贸易溢出与企业生产率之间的关系。实证结果表明,出口贸易的水平溢出和后向关联溢出均对企业生产率有显著的正效应。我们进一步的研究发现,内资企业溢出是出口贸易溢出的主要来源;对于外资企业而言,其出口贸易的水平溢出效应较小,并且其后向关联溢出效应为负;外资企业过于强势的竞争力、形成的买方势力和对知识产权的严格保护是这一现象的可能解释。
