互联网发展水平对城市创新效率的影响研究

Research on the Impact of Internet Development on Cities’Innovation Efficiency

随着信息技术时代的到来,互联网技术的发展和普及能够促进技术进步,成为经济增长方式转换的关键。在系统梳理互联网发展与城市创新效率的作用机制基础上,结合2003—2017年中国277个地级市的面板数据,实证分析了互联网发展水平对中国城市创新效率的影响效果。结果表明:互联网发展水平能够显著促进城市的创新效率,这种促进作用主要通过提升创新产出而非创新投入来实现,并随着时间趋势逐步增强;城市的物质环境和人才环境反向调节互联网发展水平对城市创新效率的促进作用,即一个城市的经济发展水平和人力资本水平越高,互联网对其创新效率的正向推动作用越小,而城市金融环境的调节作用并不显著;互联网对创新效率的影响存在显著的区域异质性,西部最大,中部和东部次之,但各区域均在2012年以后才显著提升创新效率。为了更好地挖掘创新潜力,在加强信息技术发展的同时,应进一步提高落后地区的创新环境水平。

With the advent of the information technology era,the development and popularization of Internet technology can promote technological progress and has become the key to the transformation of Chinese economic growth mode.On the basis of systematical analysis of the action mechanism of Internet development and urban innovation efficiency,combined with panel data of 277 prefecture-level cities in China from 2003 to 2017,this article empirically analyzess the effect of Internet development level on urban innovation efficiency in China.The results show that the Internet has a significant promotion effect on the improvement of urban innovation efficiency,and the promotion effect is mainly achieved by promoting innovation output rather than innovation input,and gradually strengthens with time.The urban physical environment and talent environment reversely regulate the Internet to promote the efficiency of urban innovation,that is,the higher the level of economic development and human capital of a city,the smaller the positive impact of the Internet on its innovation efficiency.While the regulating effect of urban financial environment is not significant.The influence of the Internet on innovation efficiency has significant regional heterogeneity,with the western region being the largest,followed by the central and eastern regions.However,innovation efficiency was not significantly improved in all regions until 2012.In order to better tap the innovation potential,China should strengthen the development of information technology at the same time,further improve the level of innovation environment in backward areas.
