本文基于我国2003-2014年省级面板数据,将创新和城镇化引入经济增长空间扩展模型,在揭示创新产出通过城镇化影响经济增长的内在机理并控制劳动、资本、土地、产业结构等因素影响后,采用空间计量的方法对创新与城镇化对经济增长的空间溢出效应进行经验检验。研究结果表明:(1)创新能够有效促进经济增长,创新驱动命题成立;(2)就全国以及东中西三大区域而言,城镇化对经济增长均表现出显著的正向促进作用;(3)我国省域间存在技术溢出,城镇化的创新效应存在并具有门槛特征,对地区经济增长的影响存在异质性,城镇化水平会影响地区技术的吸收能力,创新与城镇化的融合发展对促进地区经济持续健康发展具有重要作用。
Based on the provincial panel data from 2003 to 2014 in our country, this paper introduces innovation and urbanization into the expansion model of economic growth, reveals the inherent mechanism of economic output through innovation and urbanization and controls such factors as labor, capital, land and industrial structure After the impact, the method of spatial measurement is used to empirically test the spillover effects of innovation and urbanization on economic growth. The results show that: (1) innovation can effectively promote economic growth and innovation-driven proposition holds; (2) urbanization has a significant positive effect on economic growth both in China and in the three major eastern, central and western regions; (3) ) There is technology spillover between provinces in our country, the innovation effect of urbanization exists and has threshold characteristics, and the heterogeneity of the impact on regional economic growth. The level of urbanization will affect the absorptive capacity of regional technology and the integration of innovation and urbanization. Promote the sustained and healthy development of the regional economy has an important role.
