摘要
通过将国家创新型城市建设看作是创新驱动发展的自然实验,本文基于中国2003—2016年281个地级市面板数据,运用双重差分方法和三重差分方法实证检验创新驱动如何实现高质量发展。研究结果表明,创新型城市政策能够显著推动经济高质量发展,基于PSM-DID方法和多种稳健性检验,结论仍然稳健。机制分析表明,创新型城市政策通过创新要素投入与创新环境建设两种作用机制,分别产生了积极的创新效应和结构效应,二者是创新驱动实现经济高质量发展的基本途径。本文的重要政策含义在于:明确创新驱动经济高质量发展的理论机制,为继续深入推进国家创新型城市建设,提升经济高质量发展水平提供依据。
By taking the construction of national innovative cities as a natural experiment of innovation-driven development,this paper empirically tests how innovation-driven can achieve high-quality development by using the difference-in-difference method and the triple difference method based on the panel data of 281 prefecture-level cities in China from 2003 to 2016.The results show that innovative city policies can significantly promote high-quality economic development,and the conclusions are still robust based on the PSM-DID method and a variety of robustness test methods.The mechanism analysis shows that innovative city policies produce the positive innovation effect and the structural effect through two mechanisms of action:innovation factor investment and innovation environment construction,respectively,both of which are the basic ways for innovation-driven to achieve high-quality economic development.The important policy implications of this paper may lie in clarifying the theoretical mechanism of innovation-driven high-quality economic development,so as to provide a basis for continuing to promote the construction of national innovative cities in depth and improving the level of high-quality economic development.
