根据1992-2009年成都市软件产业集群内企业的数据信息,对该产业集群构建隶属网络并衍生出"企业-企业"单模网络,利用Pajek软件分别从集群企业自我中心网和整体网络两方面进行网络可视化分析,从而研究网络的演化机制。结论表明:1)集群内大多数企业未发生转型,而转型企业的演化过程遵循逐级稳步发展的态势;2)企业自我中心网表现出以同业者增多为主、企业多元化发展为辅的演化机制;3)集群整体网络表现出节点增长、关系增加的演化机制。
Abstract
Based on the enterprise data collected from the year of 1992 to 2009 in Chengdu software industry cluster, the "enterprise- enterprise" one-mode network is derived from the cluster’s affiliation network, and its evolution mechanisms are analyzed based on both aspects of the ego-centered network and the whole network through network visualization by using software Pajek. Several conclusions are drawn as follows: Most enterprises in the cluster have no transformation, and the others which have the transformation mostly follow a steady development trend. The ego-centered networks grow based primarily on the increase of the same-business enterprises, and supplement by enterprises’ diversified development. The whole network grows based on the increase of nodes and relationships.
