中文摘要：	作为企业创新活动的重要形式，企业内部的发明者合作网络已成为企业创新成果的重要来源。大量的研究围绕发明者合作网络的结构和内容与个体和企业创新之间的关系进行了广泛的探讨。然而，此类研究通常假设发明者的自我网不会随着时间的推移而变化，并将稳定性视为自我网价值的来源。事实上，由于主观和客观的原因，发明者的自我网经常发生变化。因此，基于动态视角考察发明者自我网的变化与创新之间的关系更合理，且对于推动个体的创新至关重要。 尽管越来越多的研究开始关注发明者合作网络的动态变化，但个体层面社会网络动力学的研究主要关注发明者合作网络变化的前因，并重点围绕影响网络联系形成、维持和终止以及自我网和整体网络变化等的因素进行了深入的研究。尽管越来越多的研究开始关注自我网变化或稳定性对焦点发明者创新的潜在影响，但仍缺少一致性和更细粒度的理解。因为发明者的自我网变化由新合作伙伴进入和合作伙伴退出两种基本变化驱动，但两种变化可能以不同的机制影响焦点发明者的创新，甚至可能对焦点发明者的创新产生相反的影响。因此，探讨新合作伙伴进入和合作伙伴退出对焦点发明者创新的影响机制有助于更深入的理解自我网变化与焦点发明者创新之间的关系。 因此，本研究结合社会网络理论、知识基础观、知识重组观和以合作伙伴为中心的视角，深入探讨了新合作伙伴进入和合作伙伴退出对焦点发明者创新的影响，并分析了其中介机制。具体而言，首先，从自我网层面出发，本研究分别探讨了新合作伙伴进入和合作伙伴退出如何影响焦点发明者的创新，并识别了重要的边界条件。其次，从知识层面出发，本研究重点分析了新合作伙伴进入和合作伙伴退出与焦点发明者创新之间的中介机制，并探讨了影响上述中介机制的边界条件。为实现上述研究目标，本研究基于华为2004-2021年在中国申请的专利数据，对提出的假设进行了实证检验，并得出了以下主要结论： 第一，基于社会网络动态视角和以合作伙伴为中心的视角，本研究调查了个体层面的新合作伙伴进入对焦点发明者创新的影响，并进一步探讨了新合作伙伴的自身属性（创新绩效）和网络结构属性（在合作网络中的中心性和结构洞）对上述关系的调节作用。研究结果表明平均而言新合作伙伴进入与焦点发明者的创新正相关，且新合作伙伴的比例越高越有利于焦点发明者的创新。此外，新合作伙伴的创新绩效、在合作网络中的中心性和结构洞均正向调节上述关系。即当新合作伙伴具有更高的创新绩效、在合作网络中处于中心位置以及占据更多结构洞时，焦点发明者表现出更高水平的创新。 第二，基于社会网络动态视角，本研究考察了合作伙伴退出对焦点发明者创新的影响，并进一步探讨了退出者的自身属性（过往创新绩效）及其与焦点发明者的二元关系属性（知识相似性和联系强度）对上述关系的调节作用。研究结果表明平均而言合作伙伴退出与焦点发明者的创新负相关，且退出者的比例越高越不利于焦点发明者的创新。本研究进一步发现退出者的过往创新绩效及其与焦点发明者的联系强度均正向调节合作伙伴退出与焦点发明者创新之间的负向关系。即退出者的过往创新绩效越高以及退出者与焦点发明者的联系强度越强，合作伙伴退出越不利于焦点发明者的创新。然而，退出者与焦点发明者的知识相似性对上述负向关系的负向调节作用没有得到支持。 最后，基于社会网络动态视角和知识重组的观点，本研究实证检验了新知识获取在新合作伙伴进入以及合作伙伴退出和焦点发明者创新之间的中介机制，并进一步探讨了现有知识的属性（知识的多样性）和新知识元素的属性（组合潜力和组合机会）对上述中介机制的调节作用。研究结果表明新知识获取在新合作伙伴进入和合作伙伴退出与焦点发明者之间起到部分中介作用。具体来讲，本研究发现新合作伙伴进入和合作伙伴退出分别促进和抑制新知识获取，进而分别有利于和不利于焦点发明者的创新。在此基础上，本研究发现焦点发明者现有知识的多样性负向调节新合作伙伴进入（合作伙伴退出）与新知识获取之间的正相关（负相关）关系。即相比知识多样性低的发明者，知识多样性高的发明者与新合作伙伴建立联系通常获取更少的知识。合作伙伴退出对焦点发明者获取新知识的不利影响随着焦点发明者知识多样性的提升而减弱。最后，本研究发现新知识元素的组合潜力和组合机会均正向调节新知识获取与焦点发明者创新之间的正向关系。即焦点发明者获取的新知识元素的组合潜力和组合机会越高越有利于其创新。 本研究的创新点体现在以下三个方面。首先，本研究揭示了新合作伙伴进入以及新合作伙伴的创新绩效、中心性和结构洞对焦点发明者创新的影响机理。传统的研究主要基于静态视角和以自我为中心的视角考察发明者自我网的结构和内容属性对其自身创新的影响。本研究整合了动态视角和以合作伙伴为中心的视角，较早的考察了新合作伙伴进入对焦点发明者创新的影响机理，并识别了重要的边界条件。因此，本研究弥补了传统静态研究的不足，为理解自我网变化及其影响提供了更细粒度的见解，有助于更全面的理解新合作伙伴进入这一现象的潜在影响，为探讨社会网络与创新之间的关系提供了新的研究视角。 其次，本研究揭示了合作伙伴退出以及退出者的过往创新绩效及其与焦点发明者的知识相似性和联系强度对焦点发明者创新的影响机理。先前的研究主要关注个体层面合作伙伴退出或合作关系终止的前因，鲜有研究关注合作伙伴退出对焦点发明者创新的影响。本研究基于社会网络动态视角，较早的对合作伙伴退出如何影响焦点发明者的创新进行了深入分析。因此，本研究为揭示自我网变化与焦点发明者创新之间的关系提供了更深入的见解。在此基础之上，本研究探讨了退出者的过往创新绩效及其与焦点发明者之间的知识相似性和联系强度对合作伙伴退出与焦点发明者创新之间关系的影响机理。因此，本研究识别了重要的边界条件并有助于更全面的理解合作伙伴退出与焦点发明者创新之间的关系。 最后，本研究揭示了新知识获取在新合作伙伴进入和合作伙伴退出与焦点发明者创新之间关系的中介机制，并揭示了现有知识的多样性和新知识元素的组合潜力和组合机会对上述机制的影响。首先，本研究基于社会网络动态视角，较早的探索和揭示了新合作伙伴进入以及合作伙伴退出如何通过影响新知识获取来间接促进或抑制焦点发明者的创新活动。因此，本研究在一定程度上揭示了发明者自我网变化与创新之间复杂关系的“黑箱”。其次，本研究基于知识重组观点，较早的对现有知识元素以及新知识元素的属性如何影响新知识获取及其有效性进行了深入的分析。因此，本研究揭示了现有知识和新知识及其属性在知识重组过程中的差异化影响，深化了对知识重组观点的理解。
英文摘要：	As a significant form of organizational innovation activity, intra-firm inventors’ collaboration networks have become a crucial source of firms’ innovation outcomes. Extensive research explored the relationship between the structure and content of inventors’ collaboration networks and innovation. However, such research often assumes that inventors’ ego networks are stable and regards stability as the source of their value. In fact, due to both subjective and objective factors, inventors’ ego networks frequently undergo changes. Therefore, examining the relationship between inventors’ ego networks and innovation from a dynamic perspective is not only more reasonable but also crucial for fostering individual innovation. Although an increasing number of studies have turned their attention to the dynamic changes of inventors’ collaboration networks, research on social network dynamics at the individual level mainly centers on the antecedents of collaboration network changes, with a particular focus on the formation, maintenance, and termination of network ties, as well as changes in inventors’ ego networks and whole networks. Although a growing body of research is beginning to focus on the potential impact of changes or stability in ego networks on the innovation of the focal inventor, there is still a lack of consistency and a more refined understanding. This is because the changes in an inventor’s ego network are driven by the entry of new collaborators and the exit of existing ones. However, these two changes may influence the focal inventor’s innovation through different mechanisms and may have opposite effects on the focal inventor’s innovation. Therefore, exploring the mechanisms through which the entry of new collaborators and exit of collaborators influence the innovation of focal inventors contributes to a deeper understanding of the relationship between ego network changes and focal inventor innovation. Therefore, this study integrates social network theory, the knowledge-based view, the knowledge recombination view and the perspective of alter-centric to explore the impact of the entry of new collaborators and exit of collaborators on focal inventors’ innovation, and analyzes the underlying mediating mechanisms. Specifically, starting from the level of ego networks, the study examines how the entry of new collaborators and the exit of collaborators affect focal inventors’ innovation, identifying the boundary conditions, respectively. Additionally, starting from the level of knowledge, this study examines the mediating mechanism between the entry of new collaborators and the exit of existing collaborators and focal inventors’ innovation, and explores the boundary conditions that affect the mediating mechanism. To achieve these research goals, based on the patent data filed by Huawei in China from 2004 to 2021, the study conducted empirical tests on the proposed hypotheses and draws the following main conclusions: First, based on the social network dynamics perspective and the alter-centric perspective, this study investigates the impact of the entry of new collaborators at the individual level on focal inventors’ innovation and further explores the moderating effects of new collaborators’ individual attributes (innovation performance) and network structural attributes (centrality and structural holes in the collaboration network) on the aforementioned relationship. The findings indicate that, on average, the entry of new collaborators is positively associated with focal inventors’ innovation, meaning that, a higher proportion of new collaborators is beneficial for focal inventors’ innovation. Furthermore, the innovation performance, centrality, and structural holes of new collaborators positively moderate this relationship. Focal inventors exhibit higher levels of innovation when new collaborators demonstrate greater innovation performance, hold central positions, and occupy more structural holes within the collaboration network. Second, from the perspective of social network dynamics, this study examines the impact of the exit of collaborators on focal inventors’ innovation a and further explores the moderating effects of the exiting collaborators’ individual attributes (past innovation performance) and the dyadic relationship attributes with the focal inventor (knowledge similarity and tie strength) on the aforementioned relationship. The results show that, on average, the exit of collaborators is negatively correlated with the focal inventor’s innovation, and a higher proportion of exits is more detrimental to the focal inventor’s innovation. The study also finds that the past innovation performance of the exiting collaborators and the tie strength between the exiting collaborators and the focal inventor both positively moderate the negative relationship between the exit of collaborators and focal inventor’s innovation. Specifically, when exiting collaborators have higher past innovation performance and a stronger tie strength with the focal inventor, the exit of collaborators becomes more detrimental to the innovation of focal inventors. However, However, the negative moderating effect of knowledge similarity between the exiting collaborators and the focal inventor on the aforementioned negative relationship was not supported. Finally, from the perspective of social network dynamics and the view of knowledge recombination, this study empirically examines the mediating mechanism of the acquisition of new knowledge between the entry of new collaborators, the exit of collaborators and the innovation of focal inventors. It further explores the moderating effects of existing knowledge attributes (knowledge diversity) and new knowledge element attributes (combinatorial potential and combinatorial opportunities) on the aforementioned mediating mechanism. The findings reveal that the acquisition of new knowledge partially mediates the relationship between the entry of new collaborators, the exit of collaborators and focal inventors’ innovation. Specifically, the study shows that the entry of new collaborators and the exit of collaborators respectively facilitate and hinder new knowledge acquisition, which in turn has positive and negative effects on focal inventors’ innovation. Additionally, this research finds that the diversity of existing knowledge of focal inventors negatively moderates the positive (negative) relationship between the entry of new collaborators (the exit of collaborators) and new knowledge acquisition. In other words, the inventors with higher knowledge diversity tend to acquire less knowledge. The negative impact of the exit of collaborators on new knowledge acquisition diminishes as the diversity of the focal inventors’ knowledge increases. Finally, the study finds that the combinatorial potential and combinatorial opportunities of new knowledge elements positively moderates the relationship between new knowledge acquisition and focal inventors’ innovation, indicating that a higher combinatorial potential and combinatorial opportunities of the new knowledge elements acquired is more advantageous for focal inventors’ innovation. The innovation points of this study are reflected in three key aspects. First, this study reveals the impact of the entry of new collaborators, along with their innovation performance, centrality, and structural holes, on focal inventors’ innovation. Prior research has primarily examined the influence of the structure and content attributes of an inventor’s ego network on his/her own innovation from static and ego-centric perspectives. This study combines the network dynamic perspective with an alter-centric perspective, explores the impact of the entry of new collaborators on focal inventors’ innovation, identifying some important boundary conditions. Therefore, this study overcomes the limitations of traditional static research, providing more granular insights into understanding the inventors’ ego network changes and their impacts. It contributes to a more comprehensive understanding of the potential effects of the entry of new collaborators and provides a new research perspective for exploring the relationship between social networks and innovation. Second, this study reveals the impact of the exit of collaborators, as well as the past innovation performance of the exiting collaborators and their knowledge similarity and tie strength with the focal inventor, on the focal inventor’s innovation. Previous research has mainly focused on the antecedents of the exit of collaborators or the termination of collaboration relationships. This study, from the perspective of social network dynamics, conducts an early in-depth analysis of how the exit of collaborators impacts the focal inventor’s innovation. Therefore, this research provides more granular insights into the relationship between inventors’ ego network changes and innovation, enriching the literature related to the termination of collaboration relationships. Building on this, the study explores the mechanisms through which the exiting collaborator’s past innovation performance, knowledge similarity and tie strength with the focal inventor, influence the relationship between the exit of collaborators and the focal inventor’s innovation. Therefore, this study identifies important boundary conditions and contributes to a more comprehensive understanding of the relationship between partner exit and focal inventor innovation. Finally, this study reveals the mediating role of new knowledge acquisition in the relationships between the entry of new collaborators, the exit of collaborators and focal inventors’ innovation. It reveals how the diversity of existing knowledge, the combinatorial potential and combinatorial opportunities of new knowledge impact the mechanism. From the perspective of social network dynamics, this study explores and uncovers how the entry of new collaborators and the exit of collaborators indirectly promote or hinder focal inventors’ innovation by affecting new knowledge acquisition. Thus, this study sheds light on the “black box” of the complex relationship between an inventor’s ego network change and innovation. From the knowledge recombination view, this study conducts an early and in-depth analysis of how the attributes of existing and new knowledge elements influence the acquisition and effectiveness of new knowledge. Therefore, this research reveals the differentiated impacts of existing and new knowledge and their attributes in the process of knowledge recombination, deepening the understanding of the knowledge recombination view.
