【摘要】：本文利用我国制造业企业普查数据检验了不同企业规模和集聚(城市)规模条件下,集聚动态外部性对企业创新能力的影响。结果表明:所有企业创新能力都得益于马歇尔外部性和雅各布斯外部性,同时影响程度又取决于企业规模和集聚规模。具体来说,小城市中,马歇尔外部性对企业创新能力的影响较大;大城市中,雅各布斯外部性对企业创新能力更显著。就不同规模的企业而言,小型企业显著受益于雅各布斯外部性,但大型企业很少得益于雅各布斯外部性。小城市中的小型企业的创新能力主要得益于马歇尔外部性,而大城市则主要得益于雅各布斯外部性。本文研究结论可以为区域产业政策和企业创新政策的制定提供有益的参考。
[Abstract]:This paper examines the influence of dynamic externality of agglomeration on the innovation ability of enterprises under the conditions of different size of enterprises and scale of agglomeration (city) using the survey data of manufacturing enterprises in China.The results show that the innovation ability of all enterprises is due to Marshall externality and Jacobs externality, and the degree of influence depends on the scale of firm and agglomeration.Specifically, in small cities, Marshall externality has a greater impact on enterprise innovation ability, and Jacobs externality has more significant effect on enterprise innovation ability in large cities.For businesses of different sizes, small firms benefit significantly from Jacobs externalities, but large ones rarely benefit from Jacobs externalities.The innovation ability of small enterprises in small cities is mainly due to Marshall externality, while Jacobs externality is the main reason for large cities.The conclusions of this paper can provide a useful reference for the formulation of regional industrial policy and enterprise innovation policy.
