科技人才集聚、产业集聚和区域创新能力——基于京津冀、长三角、珠三角地区的实证分析

Sci-tech talents Agglomeration , Industry Agglomeration and Regional Innovation capability—— Empirical Analysis based on the Jing-jin-ji Region, the Yangtze River Delta and Pearl River Delta

摘要:

基于Cobb-Douglas生产函数构建面板数据模型，对科技人才集聚、产业集聚及其交互作用对区域创新能力的影响进行了实证研究。研究发现：制造业集聚和生产性服务业集聚都与科技人才集聚形成正向的交互效应，推动区域创新能力的提升。科技人才集聚对于区域创新能力的贡献更大，科技人才集聚对区域创新能力的影响显著为正，而产业协同集聚的效应则显著为负，产业协同集聚对区域创新能力影响存在门槛效应，当科技人才集聚的对数值超过0.2543时，产业协同集聚对区域创新能力的总效应为正，低于0.2543时，产业协同集聚则对区域创新起着抑制的作用。

Abstract:

Based on Cobb-Douglas production function to construct the Panel Date model, this paper makes an empirical research on the impact of sci-tech talents agglomeration, industry agglomeration and their interaction on regional innovation capability. It is found that the agglomeration of both manufacturing and productive services forms positive interactive effects with the sci-tech talents agglomeration and promotes the improvement of regional innovation capability. Sci-tech talents agglomeration contributes more to regional innovation capability than industry agglomeration. It is more dependent on the level of sci-tech talents agglomeration to promote the regional innovation capability. Sci-tech agglomeration has a significant positive impact on regional innovation capability, but industry co-agglomeration has a significant negative impact. There is a threshold effect on regional innovation capability of the industry co-agglomeration. When the log value of sci-tech talents agglomeration exceeds 0.2543, the total effect of industry co-agglomeration on regional innovation capability is positive, and it is lower than 0.2543, industry co-agglomeration has an inhibitory effect on regional innovation capability.
