With an enhanced awareness of concepts such as environmental protection and sustainable development, recycling has aroused the attention of enterprises and scholars. Because of the difference between the acceptance of re-manufactured products and the popularity of new products, these two products' pricing processes are different. It is assumed that the manufacturer only produces new products in the first stage, and both new products and re-manufactured products in the second stage. Under this assumption, the pricing decisions about system of supply chain and reverse supply chain between the manufacturer and the retailer are studied under the different market situations. The results show that, in the second stage, sale prices of new and re-manufactured products are both lower than those of only new products. When the former is chosen, it will obtain more benefits. Furthermore, the retailer will do better when more money is paid for waste products. And the manufacturer's wholesale price is determined by the cost of new products, recycled products and recycling prices. The study further shows that the overall supply chain will obtain maximal profits when the retailer dominates the market, and the overall supply chain will obtain minimum profits when manufacturer dominates the market. However, when the authority between the two is not obvious, the overall supply chain profits will be in the middle.%伴随着环保思想、可持续发展观念的逐渐加强,废旧产品的回购、再利用开始越来越引起国内的企业和学者的关注.由于最终消费者对再制品的认可度与最终消费者对新产品的喜爱程度之间存在着差别,所以这两种产品在实际定价过程中有着明显的区别.本文在假定第一个生产阶段只生产新品,而第二个生产阶段可生产新品和再制品的情况下,研究了"单个制造商和单个销售商"所构建起来的闭环供应链系统中,不同渠道力量下的产品定价问题.研究结论显示,制造商同时生产新品与再制品时新品与再制品的销售价格均不超过只生产新产品情况下的销售价;此外,当制造商所支付的回收价格越高,销售商对回收终端废旧产品的努力程度越大,而制造商批发价格的制定又由新品、再制品的成本及废旧品回收价格等因素决定.研究进一步显示,以销售商为主的市场整体供应链收益最大;以制造商为主的市场整体供应链收益最小;当两者渠道力量差距不明显时,市场整体供应链利润居于中间.
