创新投入对生物医药企业知识溢出的影响机制研究

Research on the Impact Mechanism of Innovation Investment on Knowledge Spillover in Biopharmaceutical Enterprises

摘要:

加大生物医药产业创新投入，提升企业的原始创新能力，促进生物医药企业知识溢出、提升产业整体创新能力对生物医药产业长效可持续发展至关重要。本文基于内生增长理论，构建Cobb-Douglas生产函数模型，选取2015-2022年我国345家生物医药行业上市公司为研究对象，实证研究创新投入对生物医药企业知识溢出的影响机制，以及知识存量对二者影响机制的调节作用。研究发现：创新投入正向影响生物医药企业的知识溢出，且知识存量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生物医药企业的发展提出相应的政策建议。

Abstract:

Increasing innovation investment in the biopharmaceutical industry, enhancing the original innovation capability of enterprises, promoting knowledge spillover of biopharmaceutical enterprises and improving the overall innovation capability of the industry are crucial to the long-term sustainable development of the biopharmaceutical industry. Based on the endogenous growth theory, this paper constructs the Cobb-Douglas production function model, selects 345 listed companies in China's biomedical industry from 2015 to 2022 as the research object, and empirically researches the influence mechanism of innovation input on knowledge spillover of biomedical enterprises, as well as the moderating effect of knowledge stock on the influence mechanism of the two. The study finds that: innovation investment positively affects knowledge spillovers of biomedical enterprises, and knowledge stock positively regulates the promotion effect of innovation investment on biomedical enterprises; compared with non-state-owned enterprises, the promotion effect of innovation investment on knowledge spillovers of biomedical enterprises and the positive regulating effect of knowledge stock are more significant in state-owned enterprises. Finally, corresponding policy recommendations are proposed for the development of biopharmaceutical industry from both the corporate and government levels.
