摘　　要：生物医药行业具有高度复杂性、不确定性和高风险性,但当前的研究缺乏针对生物医药企业特点的专门理论框架,且所采用有关数量化指标并不能完全反映这一行业知识溢出的质量和影响力。为此,基于内生增长理论,构建柯布-道格拉斯生产函数模型,以345家中国生物医药上市公司2015—2022年的面板数据为研究样本,实证分析创新投入对生物医药企业知识溢出的影响机制,以及知识存量在创新投入与企业知识溢出之间的调节作用。结果发现:创新投入正向影响生物医药企业的知识溢出;知识存量对企业知识溢出具有显著正向促进作用,且正向调节创新投入对生物医药企业的促进作用;与非国有企业相比,创新投入对生物医药企业知识溢出的促进作用以及知识存量的正向调节作用在国有企业中更加显著。最后,从企业和政府两个层面为促进生物医药企业加大创新投入并增强其知识溢出效应提出相应的政策建议。To ensure the long-term and sustainable development of the biopharmaceutical industry,it is essential to increase investment in innovation,strengthen the original innovation capacities of enterprises,promote knowledge spillover among companies,and enhance the industry's overall innovation capabilities.However,existing research lacks a specialized theoretical framework tailored to the unique features of biopharmaceutical companies(characterized by high complexity,uncertainty,and risk),and the current use of quantitative indicators alone cannot fully reflect the quality and impact of knowledge spillovers.To this end,based on the endogenous growth theory,this paper constructs a Cobb-Douglas production function model and empirically studies the impact mechanism of innovation investment on knowledge spillover,taking 345 China's listed biopharmaceutical companies from 2015 to 2022 as research objects.Moreover,the moderating role of knowledge stock between innovation investment and corporate knowledge spillover is further discussed.The results find that innovation investment positively affects the knowledge spillover of biopharmaceutical enterprises,and knowledge stock positively regulates the promotion effect of innovation investment on biopharmaceutical enterprises.Further compared with non-state-owned enterprises,the promoting effect of innovation investment on the knowledge spillover of biopharmaceutical enterprises and the positive regulating effect of knowledge stock are more significant in state-owned enterprises.Finally,policy recommendations for knowledge management and enterprise innovation development in biomedical enterprises are proposed at both the enterprise and government levels,in order to promote increased innovation investment by biopharmaceutical companies and enhance their knowledge spillover effects.
