知识密集型服务业集聚、高技术制造业集聚及二者协同集聚的创新驱动效应

知识密集型服务业集聚、高技术制造业集聚及二者协同集聚能够促进创新进而驱动经济增长与绿色发展。运用中介效应分析方法实证检验了3种类型集聚在经济增长、绿色发展方面的创新驱动效应水平差异，结果表明：知识密集型服务业集聚能够驱动经济发展，对绿色发展的正向驱动作用不显著，创新在其集聚驱动经济增长、绿色发展的过程中未表现出显著的中介效应；高技术制造业集聚能够驱动经济发展与绿色发展，创新在此过程中的中介效应显著；相比单个产业集聚，二者协同集聚对经济发展与绿色发展具有更强的正向驱动作用，创新在此过程中的中介效应也更显著。基于上述结论，提出加快创新驱动发展的3项政策建议。

The Innovation Driving Effect of Knowledge-Intensive Business Service Agglomeration,High-Tech Manufacturing Agglomeration and Co-Agglomeration of the Two

Knowledge-intensive business service agglomeration, high-tech manufacturing agglome ration and co-agglomeration of the two can drive economic development and green development by promoting innovation. This paper empirically tests the differences in the level of innovation driving effect of the three types of agglomeration in economic development and green development using the mediating effect model, the research results show that knowledge-intensive business service agglomeration can drive economic development, but not have an significant driving effect on green development, the innovation has not shown significant mediating effect in the process of its agglomeration driving economic development and green development; high-tech manufacturing agglomeration has been capable of driving economic development and green development, and the mediating effect of innovation in these process are significant ; comparing with single industrial agglomeration, the co-agglomeration of the two has a stronger positive driving effect on economic development and green development, and the mediating effect of innovation in these process are also stronger. According to the results, three policy suggestions are proposed to accelerate innovation-driven development.
