Game analysis on minimax of honest behaviors in electronic commerce

In electronic commerce, honesty often becomes a major obstacle to a successful trading for both parties involved in the transaction because they don´t know each other. This paper applied the Game Tree to describe two types of trading models in electronic commerce, and adopted the method of minimax analysis to analyze both parties´ choice strategies in the models. Based on this, some specific conditions and suggestions have been proposed to guarantee that a transaction can be conducted honestly, i.e., a reputation system and the adjustment of certain parameters in the game process with a third party existing can help both parties choose honesty and buying in the transaction.
