Abstract: Intraorganizational knowledge flows lay the foundation for innovation through which inventors integrate existing knowledge and create new knowledge. As channels for resource transfer, research and development collaboration networks, represented by relational and structural embeddedness such as tie strength and structural holes, shape the efficiency and effectiveness of knowledge flow within organizations. However, existing studies present inconsistent views on the coupling of tie strength and structural holes, and have largely overlooked its impact on knowledge flow as well as the contingent role of inventor types. To address these gaps, this paper draws on U.S. pharmaceutical patent data to examine the influence of the coupling of tie strength and structural holes on knowledge flow within organizations, and further explores the moderating effect of inventor types. The findings indicate that the coupling of tie strength and structural holes positively affects intraorganizational knowledge absorption but negatively influences intraorganizational knowledge transfer. Furthermore, such contradictory effects vary with different inventor types. In particular, the positive impact of tie strength with structural holes coupling on intraorganizational knowledge absorption of key inventors is stronger than that of general inventors. However, such relationship is opposite in intraorganizational knowledge diffusion. These findings validate the interaction between network attributes and individual attributes, providing targeted managerial implications for understanding the coupling mechanisms of network embeddedness and optimizing knowledge flow within organizations.

摘要： 组织内部知识流动是研发人员整合既有知识与创造新知识的基础。作为资源流动的渠道，研发合作网络中的关系嵌入与结构嵌入特征具体表现为关系强度与结构洞影响组织内部知识流动的效率与效果。然而，当前围绕关系强度与结构洞之间的耦合存在不一致的观点，并且较少探讨其对知识流动的影响，以及揭示研发人员类型的权变作用。鉴于此，本文基于美国医药专利数据，研究关系强度与结构洞耦合对组织内部知识流动的影响，并进一步分析研发人员类型的调节效应。研究结果表明：关系强度与结构洞耦合对内部知识搜寻产生正向影响，但对内部知识扩散则具有负向作用；相较于一般研发者，关系强度与结构洞耦合对关键研发者内部知识搜寻的正向作用更大，而对其内部知识扩散的负向作用更小。研究结论验证了网络属性与个体属性的交互作用，为管理者准确把握网络嵌入性的耦合机制、优化组织内部知识流动提出了针对性建议。
