【摘要】 基于中国工业企业微观数据,实证研究集聚外部性与企业全要素生产率之间的关系,衡量集聚外部性对不同产权和企业类型下企业全要素生产率的影响。研究结果表明:在全样本范围下,专业化、多样化及竞争对企业全要素生产率均有显著的促进作用。在分产权和分企业类型的实证结果中,专业化对非国有企业全要素生产率表现为负向作用,但并不显著;对低技术企业全要素生产率表现为显著的负向作用,对国有企业、资源型企业及中高技术企业则表现为正向影响;多样化和竞争对企业全要素生产率始终具有正向作用。更多还原

【Abstract】 Based on the micro data of Chinese industrial enterprises, this paper conducted an empirical study on the relationship between agglomeration externalities and total factor productivity of enterprises, and measured the influence of agglomeration externalities on total factor productivity of enterprises under different property rights and enterprise types. The results show that, in the full sample range, specialization, diversification and competition have a significant effect on total factor productivity. The empirical results of property rights and enterprise types tell that specialization has a negative but not significant effect on total factor productivity of non-state-owned enterprises, a significantly negative effect on that of low-tech enterprises, and a positive effect on state-owned enterprises, resource-based enterprises and medium-high tech enterprises. Diversification and competition always have a positive effect on total factor productivity.更多还原
