摘要 运用MOA（motivation, opportunity and ability）理论、吸收能力理论、关系强度理论和结构洞理论，探究研发人员外部知识搜索对内部知识扩散的作用机制，并验证其自我中心网中关系强度和结构洞的调节效应。基于全球33家最大的医药企业1975～2014年在美国申请的专利数据，借助社会网络分析方法和固定效应的负二项回归模型进行实证分析，研究表明：外部知识搜索和内部知识扩散之间呈负向关系；关系强度和结构洞均负向调节上述关系。
Abstract：Drawing upon MOA（motivation, opportunity and ability） theory, absorptive capacity theory, tie strength theory and structural hole theory, this study explores the relationship between external knowledge search and internal knowledge transfer by inventors, and further examines the moderating effects of tie strength and structural holes in their ego networks on the above relationship. Based on American patent data of the 33 largest pharmaceutical firms worldwide from 1975 to 2014, social network analysis and negative binomial regression with fixed effects indicate that external knowledge search is negatively related to internal knowledge transfer, and both tie strength and structural holes moderate such relationship negatively.
