产业集聚与区域创新的双向影响机制及检验——基于行业异质性视角的考察

从理论和实证两个层面考察了产业集聚与区域创新的双向影响机制及产业异质性影响。采用2006—2015年中国31个省域高技术产业细分行业的面板数据,运用面板联立方程模型和动态面板模型验证了产业集聚与区域创新的双向影响机制和产业异质性影响。研究发现,产业集聚与区域创新存在显著的双向促进作用。产业集聚通过技术溢出效应和规模经济效应促进了区域创新,区域创新通过增长极效应和知识溢出效应促进了产业集聚。产业集聚与区域创新的双向促进作用存在显著的产业异质性,不同高技术产业的集聚对区域创新的促进作用呈现出差异,同时区域创新对不同高技术产业集聚的反向影响亦呈现出差异。东部地区产业集聚与区域创新的双向影响程度相对中西部地区更大。

The Interaction between Industrial Agglomeration and Regional Innovation:The Empirical Research from the Perspective of Industry Heterogeneity

In this paper,we examine the interaction mechanism and the industrial heterogeneity between industrial agglomeration and regional innovation from both theoretical and empirical perspectives,and based on the industry panel data of high-tech industries provincial-level administrative regions in China from 2006 to 2015,we examined the interactive influence and mechanism of industrial agglomeration and regional innovation by using the simultaneous equation model. The results show that industrial agglomeration and regional innovation have a significant two-way promoting effect. Industrial agglomeration promotes regional innovation through technology spillover effect and scale economy effect,and regional innovation promotes the industrial agglomeration level through the growth pole effect and knowledge spillover effect. There is significant industrial heterogeneity in the interaction promotion effect between industrial agglomeration and regional innovation. The promotion effect of different hightech industrial agglomeration on regional innovation is different,and the reverse promotion effect of regional innovation on different high-tech industrial agglomeration is also different. This study shows that industrial agglomeration and regional innovation can achieve a double synergy. It's important to focus on the interaction effects,and to maximize these effects to the greatest extent.
