基于企业网络的创新扩散过程

基于企业间合作关系网络的拓扑特征构造了具有自然选择特点的创新扩散过程:具有适应性r的创新在企业网络中扩散,并以概率P扩散到整个网络,且r越高的创新,P也越高.研究表明:创新扩散过程受网络拓扑结构和企业行为模式的影响;网络异质性越高、平均度越低时,网络结构越有利于创新的自然选择,而正的度相关和小世界效应则不利于创新的自然选择;企业行为模式的影响也很显著,主动行为模式下高适应度的创新更容易存活,而被动行为模式甚至会压制创新的自然选择;企业网络的结构性差异会显著影响网络上各种动力学过程,进而影响网络的整体功能.

Research on Diffusion of Innovation Based on Firm Network

Based on the topology of firm's cooperations network,this paper constructed the natural selection process of innovation: an innovation of fitness r diffuses in the firm's network and occupies the whole network with probability P;while the higher the fitness r is,the bigger the fixation probability P is.The results show that the diffusion process of innovation is influenced by the topology of network and behavioral mode of firm: the higher heterogeneity and the lower connectivity of network favor the selection of innovation while the positive degree correlation and small world effect go against it.Moreover,the behavioral mode of firm shows the distinct influence.The active behavioral mode favors the passive of higher fitness while the passive behavioral mode even suppresses the selection of innovation.The structural difference of firm network will remarkably influences the dynamics on network,and then influences the integral function of network.
