| 摘 要： | 根据WS小世界模型的思想，构建了从规则网络到随机网络的一系列扩散网络图，通过虚拟采纳个体的决策过程，研究了网络结构与性质对创新微观采纳和宏观扩散的影响。不同于已往的研究，本文将创新采纳与创新扩散统一起来，运用复杂网络的方法，研究了网络结构与创新扩散之间的动态相互关系。数值模拟结果表明：存在介于规则网络和随机网络之间的小世界扩散网络；外部因素和内部因素共同决定一个成功的扩散过程；网络的簇系数决定扩散的最终水平，而网络平均距离决定扩散速度；网络个体间的异质性程度越大，越不利于创新扩散。

| Abstract: | According to the idea of WS Small-World Model,this paper construct a series of diffusion network graphs which range from regular graph to stochastic graph.By simulating the decision-making process of adoption individuals,we study the influence of network structure on innovation micro-adoption and macro-diffusion.Unlike the previous studies,this paper unites the innovation adoption and diffusion as a whole and probes into the dynamic relationship between network structure and innovation diffusion by using the method of complex network.The numerical simulation results illustrate: there is a small-world diffusion network between regular and stochastic graph;the external and internal factors decide a successful diffusion process together;the network cluster coefficient decides the diffusion ultimate level and network average length determines the diffusion velocity;the extent to the network individuals' heterogeneity is in inverse proportion to the ultimate innovation adoption rates. |
