产业集聚与知识溢出的交互作用:基于联立方程的实证检验

Interaction of Industrial Agglomeration and Knowledge Spillovers:An Empirical Test Based on Simultaneous Equation

产业集聚和知识溢出是经济生活中的两种重要现象,两者是否存在互动关系?纵观现有的国内外文献,单独研究产业集聚和知识溢出的文献较多,关注两者互动关系的文献却并不多见。文章基于产业经济学和技术经济学中的相关理论,在深入剖析知识溢出促进产业集聚、产业集聚推进知识溢出以及两者互动机制的基础上,分别通过单方程模型、联立方程模型实证检验了产业集聚与知识溢出之间的单向关系和互动关系。最后根据理论分析和实证结果,提出促进产业集聚和知识溢出良性互动的对策建议,以期充分发挥产业集聚和知识溢出对区域经济发展的促进作用。

Industrial agglomeration and knowledge spillovers are two important phenomena in the economic filed. Is there any interactive relationship between them？ According to the existing domestic and foreign literatures, there are many literatures about either industrial agglomeration or knowledge spillovers, but few literatures about the interactive relationship between them. This paper is based on the related theories of industrial economics and technical economics. The paper, by deeply ana- lyzing knowledge spillovers to promote industrial agglomeration and industrial agglomeration to promote knowledge spillovers as well as the interaction mechanism between them, empirically tests unidirectional relationship and interaction relationship between industrial agglomeration and knowledge spillovers by using single equation model and simultaneous equation model respectively. Finally, the paper, on the basis of theoretical analysis and empirical results, proposes countermeasures and sug- gestions to promote the positive interaction between industrial agglomeration and knowledge spillovers in order to give full play to the role of industrial agglomeration and knowledge spillovers in improving regional economic development o
