【摘要】 信息化对于促进新旧动能转换、加快创新型国家建设具有非常重要的意义。本文从异质性和非线性视角,利用中国2003-2016年省际面板数据,使用面板固定效应模型和门槛模型,分析信息化投资与区域创新能力之间的关系,研究发现,信息化投资显著提升了区域创新能力,在人力资本、金融发展、技术市场和交通基础设施方面水平较高,地方政府干预程度较小的地区,这种作用更加明显;2006年国家信息化发展战略实施之后,信息化引致的创新溢出效应显著增强;信息化投资对区域创新能力的促进作用不仅没有呈现明显的边际递减效应反而表现出显著的网络效应,即当网络用户规模超过24.19%的临界值时,信息化投资对区域创新能力的促进作用更为强劲。更多还原

【Abstract】 Informatization is of great significance for China to promote the new and old kinetic energy conversion and to speed up the construction of an innovation-oriented country.From the perspective of heterogeneity and nonlinearity,this paper used the provincial panel data of China from 2003 to 2016 and panel fixed effect model and panel threshold model to empirically analyses the relationship between informatization investments and regional innovation capability.The study finds that informatization investments significantly improve regional innovation capability,especially in areas with high levels of human capital,financial development,technology market and transportation infrastructure,and low level of intervention from local government. Since the implementation of the national informatization development strategy in 2006,the innovation spillover effect caused by informatization has been significantly enhanced. Moreover,informatization investments have not yet demonstrated obvious marginal decreasing effect on regional innovation capability,but have a significant network effect.That is,when network users exceeds the critical value of 24.19%,informatization investment will promote regional innovation capability more strongly.更多还原
