点战略性技术创新作为政府支持企业创新活动的重要模式,是实现产业自主可控的重要路径。本文以2010一2021年111家制造业单项冠军企业为样本,从企业与政府研发目标的匹配性视角阐述了战略性技术创新内涵,并提出了战略性技术创新投入的测度方式,探究了企业战略性技术创新对产业自主可控水平的促进作用及其主要机制。研究发现,企业战略性技术创新能够促进产业自主可控水平提升。机制分析表明,战略性技术创新投入可以通过缓解创新融资约束的基本机制、促进组织边界延伸的关系强化机制、推动技术迭代升级的资源集成机制提升产业自主可控水平。进一步分析发现,战略性技术创新投入对产业自主可控水平存在显著的中长期影响,民营企业战略性技术创新投入对产业自主可控水平的短期作用更强。非战略性技术创新对产业自主可控水平也存在正向影响,国有企业的战略性与非战略性技术创新投入之间存在替代效应。本文丰富了产业自主可控水平影响因素的相关研究,可为企业技术创新战略选择和高质量发展提供借鉴。
