In this paper, a comprehensive numerical study that investigates the evolutionary process of condensed subgroup in political participation based on mobile phone was carried out, putting forward the conception of “condensed subgroup cardinality” considering that it is a finite Markov chain. Then a mathematical model was constructed which allows us to depict the evolutionary process of condensed subgroup and analyze a public media forum based on mobile phone with accuracy. The numerical result demonstrates the usability of this model in predicting the evolutionary process of virtual condensed subgroup based on mobile phone. Analyses on the evolutionary mechanism of condensed subgroup were also given and finally a preliminary stochastic differential equation was advanced to describe it.
