技术创新网络节点退出因素实证研究

Empirical Study on the Factors of Technology Innovation Network Node Exit

技术创新网络中节点的退出会影响网络的稳定性,甚至导致网络瓦解。研究网络中节点退出的影响因素,有助于网络中节点关系的治理。使用社会网络分析法和统计分析法,以集成电路产业专利合作网络为例对节点退出影响因素进行分析。研究表明,节点规模越大、网络关系密度越大、节点中间中心性越大,节点越不易退出网络;网络规模多样性越大、网络规模差异性越大,节点越容易退出网络。

Nodes exit from technology innovation network will affect stability of the network, even lead to network collapse. The study on influencing factors of nodes exit from network will help nodes＇ relationship management. This paper analyzes influencing factors of nodes exit as an example of the patent cooperation network based on social network analysis and statis- tical analysis. Studies show that the larger the size of node, the higher the density of the network and the higher the node centrality degree would be ; node is more difficult to exit the network ; the larger the diversity of network size, the larger the difference in size would be, and node is more likely to exit the network.
