基于信息扩散理论,利用演化博弈的方法建立有限理性条件下潜在信息吸纳者间的演化博弈模型,分别从科技信息扩散生命周期的不同阶段探讨潜在信息吸纳者间的相互作用对宏观扩散的影响机制。研究结论表明:在介绍期,潜在信息吸纳者趋向于共同吸纳,表现出协同效应;在成长期,潜在信息吸纳者数量迅速增多,即科技信息扩散速度最快;在成熟期,潜在信息吸纳者趋向于单独吸纳,科技信息扩散速度减慢;在衰退期,潜在信息吸纳者趋向于共同不吸纳,即科技信息退出市场,生命周期停止。
The paper establishes an evolutionary game model between potential absorbers under bounded rationality based on information diffusion theory and explores effects of interaction between potential absorbers on macroscopic diffusion from each period of life cycle. The research shows that: during the introduction period, both potential absorbers tend to ab- sorb the S&T information, which presents the synergistic effect; the number of potential absorbers increases rapidly and the rate of S&T Information diffusion gets its peak during the growth period; potential absorbers tend to result in solo absorbing S&T information and the rate of diffusion slows down; neither of potential absorbers tends to absorb S&T information, which indicates the S&T Information is supposed to withdrawal from market. It comes to an end of the life cycle of diffusion.
