关键核心技术创新是培育新质生产力的重要源泉。本文以2010—2022年战略性新兴产业上市公司为样本，探究关键核心技术创新对企业新质生产力的影响。研究发现：焦点企业关键核心技术创新能够驱动同业企业新质生产力提升；机制分析表明，焦点企业关键核心技术创新通过衍生技术创新，推动同业企业新质生产力水平提高；技术邻近性和社会邻近性在关键核心技术创新与同业企业新质生产力之间发挥负向调节作用。本研究揭示了关键核心技术创新对企业新质生产力的正向溢出效应及其作用机制的“黑箱”，对于找到加快培育新质生产力的着力点，增强高质量发展的新动能具有参考价值。

   Key core technology innovation is a vital source of new quality productive forces. Using the sample of listed companies in the strategic emerging industries from 2010 to 2022, this paper examined the effect of key core technology innovation on firms′ new quality productive forces. The study found that focal firms′ key core technology innovation has significant positive spillovers, and enhances peer firms′ new quality productive forces. The mechanism analysis further revealed that the focal firms′ key core technology innovation promotes the peer firms′ new quality productive forces by stimulating derivative technology innovation. Technological proximity and social proximity play negative moderating roles in the relationship between focal firms′ key core technology innovation and peer firms′ new quality productive forces, while geographical proximity is not significant. This research has uncovered the "black box" of the positive spillover effect of key core technology innovation on enterprises′ new quality productive forces and its mechanisms, and it will offer useful guidance for identifying effective pathways to cultivate new quality productive forces and sustain high-quality economic development.
