关键研发者自我中心网络变化对企业创新绩效的影响:以整体网络为中介变量

关键研发者作为组织创新的重要参与者,对创新绩效具有显著影响,但其影响机制不明确。以整体网为中介变量,利用36家通讯制造企业专利数据,分两个步骤探究关键研发者对创新绩效的影响机制。第一步,探索关键研发者的个人网络特征、网络规模及网络密度变化对整体合作网络和知识网络中介中心势的影响;第二步,研究整体网络的中介中心势变化(正向和负向)与创新绩效的关系。结果表明:在合作网络中,关键研发者自我中心网络规模变化幅度增大会引起整体合作网络中介中心势变化幅度增大;关键研发者引起的合作网络中介中心势变小会使企业创新绩效显著降低;在知识网络中,关键研发者自我中心网络规模与网络密度变化幅度增加均会使整体知识网络中介中心势变化幅度显著增大。由关键研发者引起的知识网络中介中心势变小会使企业创新绩效显著提升。

The Research on the Impact of the Ego-Network’s Changes from the Key Inventors to the Innovation Performance: the Whole Network as an Intermediary Variable

Key inventors as an important participant in organizational R & D has a significant impact on innovation performance.But its impact mechanism is not clear.In this paper,the whole network as an intermediary variable,we use 36 communications manufacturing enterprise patent data,in two steps to reveal the impact mechanism of the key inventors on the R&D performance.Firstly,from the respective of cooperative network and the knowledge network,considering the influence of size and density of network’s change on the rangeability of network’s betweenness centrality.Moreover,this paper divides the rangeability of two network’s betweenness centrality into the positive and negative changes,the effects of these two changes on organizational innovation performance are discussed respectively.The results show that:①the key inventor can influence the rangeability of the cooperative network’s betweenness centrality by changing rangeability of the size of self-cooperation network,and decrease of the rangeability of the cooperative network’s betweenness centrality will cause the enterprise’s innovation performance decrease；②the key inventors can influence the rangeability of the knowledge network’s betweenness centrality by changing rangeability of the size and density of self-knowledge network,and decrease of the rangeabilith of the knowledge network’s betweenness centrality will cause the enterprise’s innovation performance increase.
