摘　　要：采用有向加权网对集群网络进行更加现实的刻画,从企业微观创新决策行为角度出发,通过构建随机阈值模型,运用仿真方法探讨了不同网络类型集群创新扩散的稳定性和脆弱性问题。研究结果表明:集群网络结构对创新扩散的稳定性和脆弱性具有明显的影响;小世界网络集群的鲁棒性较差而脆弱性不显著;相比而言,无标度网络集群的稳定性更好但脆弱性更明显;还分析了集群内部企业的决策方式对创新扩散稳定性和脆弱性的影响,进一步从网络角度说明了不仅是网络连接的方式包括权重、方向等,而且网络节点企业的决策行为都对集群创新扩散的鲁棒性和脆弱性产生影响。Combining weighted directed network with stochastic threshold model to delineate the cluster networks from individual firm decision perspective,this paper studies the robustness and fragility of innovation diffusion in an industry cluster through computer simulation.The results indicate that cluster network structures have significant impact on both robustness and fragility of innovation diffusion.While clusters with small-world network have weak robustness as well as lower fragility,clusters with scale-free network have good robustness and higher fragility.In addition,this paper also analyzes the influence of firms＇ decision modes on diffusion process,showing that the robustness and fragility of innovation diffusion process is not only affected by cluster network structure bus also by firms＇ decision behavior at micro-level.
