【摘要】：在网络多样性与子群相关研究基础上,将分裂断层理论引入技术创新网络,从身份、地理和知识三个多样性属性分析分裂断层在技术创新网络中的具体表现。利用2000年至2013年我国电子信息产业联合申请专利为样本构建组织间技术创新网络,运用多元分层回归方法实证检验分裂断层、成员异质性与位置嵌入性对子群结构的共同影响。研究结果表明:由多个不同成员构成的技术创新网络,节点属性聚合能产生潜在的分裂断层,但分裂断层对子群极化的直接影响并不显著;然而,在控制成员异质性或位置嵌入性的共同效应后,分裂断层的直接作用变得显著,并且当成员异质性程度适中时,分裂断层对子群极化的影响比成员异质性很低或很高时更强;此外,当位置嵌入离散性程度较高时,分裂断层对子群极化的作用显著提升。研究结论为理解技术创新网络结构变化的微观过程提供了新的理论视角,也对探索网络子群形成和发展的内在机理具有指导意义。
[Abstract]:Based on the research on the relationship between network diversity and subgroup, the split fault theory is introduced into the technological innovation network, and the concrete performance of the split fault in the technological innovation network is analyzed from the three diversity attributes of identity, geography and knowledge.From 2000 to 2013, the joint patent application of electronic information industry in China is used as a sample to construct an inter-organizational technological innovation network. The multivariate stratification regression method is used to empirically test the split fault and the influence of member heterogeneity and location embeddedness on the subgroup structure.The results show that the clustering of node attributes can produce a potential split fault, but the direct effect of the split fault on the polarization of the subgroup is not significant.After controlling the common effect of member heterogeneity or position embeddedness, the direct action of splitting fault becomes significant, and when the member heterogeneity is moderate, the effect of splitting fault on subgroup polarization is stronger than that of member heterogeneity.In addition, the effect of splitting faults on the polarization of subgroups is significantly enhanced when the degree of embedding dispersion is high.The research results provide a new theoretical perspective for understanding the microscopic process of network structure change of technological innovation, and also provide guidance for exploring the internal mechanism of the formation and development of network subgroups.
