Abstract:Aiming at twostage reverse supply chain which consists of one manufacturer and one thirdparty recycler, a game model of knowledge sharing among reverse supply chain enterprises is proposed. Then the equilibrium strategies of knowledge sharing in reverse supply chain are indicated with the model. Furthermore, two conditions for cooperation are also discussed in the paper, which are: i) manufacturers’ share ratio of cost saving must be greater than a threshold value; ii) manufacturers’ proportion of the overall benefits must be greater than manufacturers’ costsharing ratio of knowledge sharing. Finally, the costsharing ratio of knowledge sharing and the amount of overall recycling which have effect on the amount of knowledge sharing and the costsharing ratio and marginal revenue which have effect on the costsharing ratio of knowledge sharing are both analyzed.
