摘要
无标度网络的发现,为人类认识复杂网络提供了一个全新的思路,而BA模型的建立为研究复杂网络提供了一个很好的方法。在BA模型的择优连接机制中加入适应度和度饱和值来模拟集群创新网络演进过程,进而对此类集群创新网络的无标度性特征进行模拟分析。研究得出,基于焦点企业成长的集群创新网络是一类异质性的网络,并具有集聚性、稳定性和脆弱性的特征。
The discovery of scale - free network provides people with a brand new thought for the study of complex .network, and the built of the BA model offers us with a good method on the study of complex network. Under the perspective of focal firms, it added de- gree fitness and degree saturation value in the prior joint mechanism of the BA model, to simulate the evolution process of cluster inno- vation network based on focal firms growth, and then to simulate and analyze the characteristics of such cluster innovation network. The research concluded that the cluster innovation network which based on focal firms is a kind of heterogeneous network, and possesses the nature of agglomerate, stable and vulnerable.
