摘　　要：为厘清研发外部性如何影响数字化对绿色创新的作用,以2012—2022年中国A股工业上市企业为例,探究企业数字化对绿色创新的影响以及研发外部性的调节作用,并考察企业生命周期理论和政府补贴的异质性。实证结果表明,工业企业数字化显著促进绿色创新,在缓解内生性问题后结论稳健;行业研发外部性会弱化数字化对绿色创新的促进作用,通过稳健性检验后结论不变;异质性分析结果表明,行业研发外部性对成熟期工业企业的影响效果更显著,政府补贴能够有效缓解行业研发外部性的负向影响。To clarify how R&D externality affect the role of digitization in green innovation,A-share industrial listed companies in China from 2012 to 2022 were used as an example to explore the impact of enterprise digitization on green innovation and the moderating effect of R&D externality.The heterogeneity of enterprise lifecycle theory and government subsidies was also examined.The empirical results show that industrial enterprise digitization significantly promotes green innovation,and the conclusion is robust after alleviating endogenous problems.The R&D externality weakens the promotion effect of digitization on green innovation,and the conclusion remains unchanged after robustness tests.The results of heterogeneity analysis show that the impact of industry R&D externality on mature industrial enterprises is more significant,and government subsidies effectively alleviate the negative impact of industry R&D externality.
