【摘要】 以企业为主体打造战略联盟是中国企业打破外部创新路径限制，推动创新突破的现实基础。本文基于2010—2022年中国上市公司发明专利相关数据，以专利间引用关系为基础，采用FO算法构建创新突破的测度指标，探究企业战略联盟对创新突破的影响及作用机制。研究发现，企业战略联盟能够促进创新突破。机制检验表明，企业战略联盟通过提升资源配置效率、拓展知识宽度、提高风险共担能力三方面促进创新突破。异质性检验发现，在医疗研发和化工能源行业企业、非合资子公司中，企业战略联盟对创新突破具有更为显著的提升效应。本文为理解企业战略联盟助推创新发展提供新的实证证据，也为企业构建自身创新体系、实现技术路径突破提供启示与参考。更多还原

【Abstract】 Establishing strategic alliances with enterprises as the core actors constitutes a critical foundation for Chinese firms to overcome constraints in external innovation pathways and achieve innovation breakthroughs. Drawing on patent data from Chinese listed companies between 2010 and 2022, and leveraging citation networks among patents, this study employs the FO algorithm to construct a measurement index for innovation breakthroughs and investigates the impact and underlying mechanisms of enterprise strategic alliances on such breakthroughs. The findings indicate that strategic alliances significantly enhance innovation performance. Mechanism analysis reveals that these alliances facilitate innovation breakthroughs through three primary channels: improving resource allocation efficiency, broadening knowledge acquisition, and strengthening risk-sharing capabilities. Heterogeneity analyses further show that the positive effects are more pronounced in the pharmaceutical R&D and chemical energy sectors, as well as in firms without joint venture subsidiaries. This study contributes novel empirical evidence to understanding how strategic alliances foster innovation, and offers practical insights for enterprises seeking to develop robust innovation systems and achieve technological path-breaking.更多还原
