生物技术产业集群技术网络演化研究——以波士顿和圣地亚哥为例

Research on evolution of technology network of biotechnology clusters:In the cases of boston and san diego

论文分析生物技术产业集群的技术网络结构,以及现有网络结构影响之后技术间新连接形成的机制。研究样本为美国波士顿和圣地亚哥集群1976-2006年间的技术网络。通过网络可视化技术,论文发现两个集群都存在组元分割的网络结构。在网络演化过程中,存在特定技术领域兴起和衰落的现象。基于负二项回归,研究发现整体网中心性高的技术会得到更高的被引数量,而桥接位置的作用在两个集群间存在差异,集群的演化是一个涌现过程。

We explore the network structure of technology in biotechnology industrial clusters and how prior structure affects formation of ties among technologies from a network perspective. We select technology networks in Boston and San Diego from 1976 to 2006 as cases. Based on visualization techniques of networks,we find both clusters have a separate components structure pattern. We also observe a phenomenon of boom and decline of technology during the evolution process. Based on Negative Binomial Regression,we find that core position of global network has a positive relation with formation of ties. Effects of bridge position are different in two clusters.Evolution of clusters is an emerging process.
