Abstract: A recycling and remanufacturing system consisting of the remanufacturer， retailer and thirdparty recycler was investigated. In this dualchannel recycling model， product recycling of the closedloop supply chain was determined by the remanufacturer and thirdparty recycler. In addition， pricing mechanisms and coordination strategies were analyzed under decentralized and centralized decision with the method of game theory. Based on the Rubinstein bargaining model and discount factor theory， coordination strategy and Pareto improvement were established. Finally， a numerical example was given to illustrate the effectiveness of the pricing mechanisms and coordination strategies. This study proves that the dualchannel recycling model can not only improve all parties’ benefits but also promote the overall efficiency of this recycling and remanufacturing system.
