Urbanization,Technology Innovation and Economic Growth

经济增长中技术创新的作用日益突出,城市在专业化与多样性、人力资本积累、信息交流网络形成、交易效率提高以及基础设施等方面的优势使其有利于技术创新的产生及扩散,城市化通过技术创新的中介效应推动经济增长。时序及横截面数据的相关分析显示,我国城市化水平与技术创新之间高度正相关,投入产出模型证实城市化有利于技术创新;基于省级面板数据的多模型估计发现,城市化与技术创新对经济增长具有正向促进作用,当前技术创新的中介效应还不是十分明显,结论对于提升技术创新能力,推动经济持续增长具有启示意义。

The capacity of technology innovation is important to economic growth. The characters of cities are propitious to innovation and provide appropriate conditions for innovation diffusion, Technology innovation can be look as the intermediary factor between urbanization and economic growth. Empirical analysis shows that urbanization is highly correlative with technology innovation. Urbanization is really propitious to technology innovation, Urbanization and technology innovation promote economic in some extent. The effect for technology innovation to combine urbanization with economic growth is not obvious. In the end, recommendations are discussed.
