摘要
在基于协调博弈和动态网络的基础上,构建了一个社会网络与创新扩散的共生演化模型,采用仿真与计量相结合的方法,分析了创新扩散、网络整体收益和社会网络之间的相互影响。研究表明,个体行为与社会网络结构对创新扩散的影响,取决于创新自身相对优势的大小,具有相对优势的创新在密集的网络中和规则连接方式下更容易扩散。网络整体收益不仅与创新自身以及采用个体的自身特征有关,也与局部网络效应强弱和个体之间建立联系的成本相关。创新扩散微观层面中个体策略选择行为特征会导致社会网络结构特征(如网络异质性、小世界效应,度相关性)的变化。
Based on coordination game and dynamic network, this paper uses a co-evolution model with so- cial networks and innovation diffusion to analyze the interplay of innovation diffusion process, the total benefits and structure of the social networks,by using the methods of simulation and ecconometrics. The results show that the impact of agent action and social network structure on innovation diffusion has rela- tionships with the relative advantage of innovation itself. When the relative advantage of innovation is good enough, it is easser to diffuse in dense network or by the regular connection rules in local network. The to- tal benefits of the social networks do not only depend on the characteristics of innovation and adopters, but also the local network effects and structure of the social networks. Furthermore, the strategic choice of agents in the micro-level of innovation diffusion changes the characteristics of social networks, such as the heterogeneity of degree distribution, the small world property and degree correlation. Those conclusions not only give insight into the dynamic coupling and bidirectional feedbacks between social networks and in- novation diffusion, but also give us a new angle of view to understand the inherent mechanisms of innova- tion diffusion.
