The simulation findings uncover that : either a higher inefficiency level of e - marketplace, or a higher opportunity cost that a seller in the traditional marketplace takes, or a low upper limit of active sellers in e - marketplace, or a higher probability of taking stochastic actions, or less information to form expectation, can be propitious for spurring the shift from the traditional marketplace to the e - marketplace. as for the popular “ thorough shift ” presumption, this paper puts forward that, an aggressive shift from traditional marketplace to e - marketplace is probably built on an effort by the buyer to constrain his own bargaining power or to share benefits with the supplier. by developing economic models and leveraging the general game theory, this paper also finds out that cost is the critical factor that governs the evolution of monopolistic market, monopolistic competitive market and oligarchic market
