非对称视角下技术创新网络社群结构涌现及其对双元创新的影响研究

Study on the Emergence of Technological Innovation Network Community Structure and Effect on Ambidexterity Innovation in Asymmetric Perspective

针对介于全局网络与自中心网络间的社群现象及其网络结构的创新悖论,分析了不同层面网络社群结构的涌现特征,从组织间关系的非对称视角,探究网络社群动态变化对双元创新的差异性影响。利用高科技生物制药行业的合作与专利数据,使用快速压缩社群识别算法和多元回归模型进行实证检验。研究结果表明:宏观层面的全局网络存在显著"抱团"的多社群巨元组结构;中观层面的网络社群存在选择偏好的核心-边缘结构;微观层面社群组织动态的跨社群运动和成员流动二维变化加剧;社群动态的二维变化对突破式创新具有正向影响,与渐进式创新呈现倒U型关系;位置非对称性正向调节社群动态对双元创新的影响,技术非对称性的调节作用不显著。研究结论有助于揭示技术创新网络社群的合作创新模式,对提升组织创新能力,维持创新网络平稳运行具有重要意义。

In order to deal with the technology innovation community phenomena between global network and ego network, and the innovation paradox of radical and incremental innovation in the network community, this paper analyze the emergence characteristics of technological innovation network community structure on different levels to explore the effect of dynamic community structure on ambidexterity innovation in asymmetric perspective. Then an empirical test is made by fast unfolding of communities＇ algorithm and multiple regressions with high-tech bio pharmacy industry data. The results show that there exists a giant component of multiple network communities on the macro level of the global network ; the meso level of network community has selection preference features with core-periphery structure; in the micro level of ego network , the two dimensional dynamic individual behaviors are drastic changed . Membership turnover and movement across different network communities not only have significant positive relationship with radical innovation , but also have the approximate U-shaped correlation with incremental innovation. In the relationship between dynamic communities and ambidexterity innovation, the posi- tion asymmetry moderated effect is confirmed, but technology asymmetry has no significant moderated effect. This research can reveal the collaboration pattern of network communities. It is significant for the behavior of innova- tion organization and stability of technology innovation network.
