Abstract: The reverse auctions have made great challenge to the operational model of the traditional supply chains.It is the most urgent task for buyers and suppliers to integrate this new tool into the operational process of enterprises in developing of e-business.Firstly,a non-cooperative static game is constructed to analyze how to achieve long-term cooperative conditions of supply chain,and which is the pure strategies Nash Equilibrium in this paper.Then,basing on that,the evolution of the paths and the influence of factors are analyzed with the idea of evolutionary game.At last,the influence of diversity decision-making parameters and variation of initial condition on evolution result through reliable numerical simulation.

Key words: supply management, reverse auction, evolutionary game, opportunistic bidder
