Abstract: In this paper, based on the data of Chinese biotechnology firm in 2003-2016 and using fixed-effect Quasi-Poisson model, we investigated the effect of firm’s geographic proximity to other firms in the same industry on its innovative performance, and at the same time, we also consider the structure of the firm’s internal inventor collaboration network and investigated its moderating effect. The results show that geographic proximity promotes firm’s innovation performance; the clustering of intra-firm network positively moderate the relation between geographic proximity and innovative performance; the average path length of the intra-firm network negatively moderate the relation between geographic proximity and innovative performance. The conclusion in this paper provide theoretical guidance to the coordination of firm’s internal knowledge network.

摘要： 本文运用2003-2016年中国生物技术企业的面板数据，考察了地理邻近对企业创新绩效的影响，同时将企业内部网络特征纳入研究框架，分析了企业内部网络的集聚度和平均路径长度对地理邻近与企业创新绩效关系的调节作用。研究结果表明，地理邻近促进企业创新绩效的提升；企业内部网络的集聚度正向调节地理邻近对企业创新绩效的促进作用；企业内部网络的平均路径长度负向调节地理邻近对企业创新绩效的促进作用。本文研究结论对中国企业的内部知识结构设计提供借鉴。
