摘要
在微分系统建模理论的基础上,构建了互联网市场中存在细分市场的网站竞争模型,用全局定性分析的方法对三网站竞争模型进行了稳定性分析.分析结果显示:在强竞争市场中,市场细分为弱势网站提供了在竞争中生存甚至胜出的机会,而在弱竞争市场中,市场细分为网站带来的却是较低的市场份额;数值仿真验证了稳定性分析结果的正确性.
A model to describe the competitive dynamics of websites is presented on the internet market on the basis of the theory of differential system modelling,and the stability of the model for three websites is analyzed by means of global qualitative analyses.The analytical results show that some weak websites can survive,even win through market segmentation in the strong competitive environments.While in weak competitive environments,market segmentation can only lead to lower market share.By numerical simulation,the results of stability analyses are verified.
