摘要
区域科创走廊是优化创新要素配置的重要途径,也是驱动企业科技创新的策源地。基于创新链视角,本文以长三角G60科创走廊试点为准自然实验,选取2010—2021年中国A股上市公司为研究样本,运用双重差分模型探究G60科创走廊建设对企业双元创新的作用路径及效果。研究结果表明,企业所在地加入G60科创走廊后能够显著促进企业的实质性创新和策略性创新,且对实质性创新的激励效应更大。机制研究发现,科创走廊建设主要通过缓解融资约束和优化人力资本两条渠道提升企业创新效应。异质性分析表明,G60科创走廊对企业双元创新的激励效应在小规模企业、非国有企业和高吸收能力企业中表现得更为突出。本文不仅为我国稳步推进科创走廊建设、完善创新链配套体系提供了一定的经验指导,而且为引导我国企业自主创新提供了实践参考。
Regional S&T(S&T)innovation corridor serves as a crucial pathway for optimizing allocation of innovation elements and acts as a wellspring for driving technological innovation in enterprises.Based on the innovation chain perspective,this paper took the pilot G60 S&T innovation corridor in the Yangtze River Delta as a quasi-natural experiment and selected Chinese A-share listed companies from 2010-2021 as the research sample.We used the differences-in-differences model to explore the path and effect of the G60 S&T innovation corridor on the dual innovation of enterprises.The research results indicated that joining the G60 S&T innovation corridor significantly promotes both substantive and strategic innovation of enterprises,with a greater incentive effect on substantive innovation.The mechanism study revealed that construction of the S&T innovation corridor mainly enhances the innovation effect of enterprises through two channels:easing financing constraints and optimizing human capital.The heterogeneity analysis showed that the incentive effect of the G60 S&T innovation corridor on enterprises′dual innovation is more prominent in small-scale enterprises,non-state-owned enterprises,and enterprises with high absorption capacity.This paper has not only provided some empirical guidance for China to steadily promote the construction of the S&T innovation corridor and the improvement of the supporting system of the innovation chain but also offered some practical references for guiding the independent innovation of Chinese enterprises.
