Abstract: In order to remedy deficiencies in present studies on cooperation between supply chain enterprises, a bargaining game model is proposed with important traits of random offer pattern and breakdown possibility during the negotiation. Based on this model, two conditions of with and without other options are discussed respectively. It is proved that the subgame perfect equilibrium result is unique under either condition. Then subgame perfect equilibrium strategies of both sides are given out.Further analysis of gaming result proves that this game model has three characteristics of first mover advantage, external revenue pertinence as well as cooperation advantage.
