电子商务的迅速发展和产品回收法规的实施，使越来越多的制造商开始重视网络渠道和产品再制造策略。采用数理建模方法研究传统背景下制造商的基本定价策略，给出制造商实施双渠道和产品再制造策略时采取的统一定价和利润最大化两种定价策略。以利润最大化模式为基础给出双渠道策略和再制造两种衍生定价策略，以基本定价策略下制造商和零售商的价格和利润为基础对上述策略进行研究，并分别讨论零售商市场份额、网络渠道销售成本、价格弹性系数和渠道价格敏感性系数等因素对4种定价策略影响。探讨不同参数对不同定价策略的影响。研究结果表明，当再制造产品成本较低时，实施产品再制造策略可以同时提高制造商和零售商的利润，使整个供应链系统得以优化；网络渠道的引入显著增加制造商的利润，降低零售商的利润，导致渠道冲突，此时制造商采取产品再制造策略可同时提高制造商和零售商的利润；市场的价格弹性系数对帝3造商引入网络渠道有重要的影响。

英文摘要：

With the development of e-commerce and the implementation of product recycling regulations, the Internet channel and remanufacturing strategies increase much attention by manufacturers. Employing mathematical modeling method, this paper dis- cusses manufacturers＇ basic pricing strategies in the traditional background and provides the equal-pricing strategy and the total profits maximization strategy when manufacturers implement the dual-channel and product remanufacturing strategy. We describe derivative pricing strategies, i.e. dual channel strategy and remanufacturing strategy, based on the total profit maximum strategy and explore the two strategies based on the manufacturers＇ and retailers＇ prices and profits in the basic pricing strategy. We also explore the effects of market share of retailers, costs of Intemet channel marketing, price elasticity and channel price sensitivity on four pricing strategies, as well as the impacts of various parameters on the different manufacturer＇s pricing strategies. The re- suits show that： ①product remanufacturing strategies contribute to increase manufacturers＇ and retailers＇ profits so as to optimize the whole supply chain when the remanufactured products＇ cost is low; ②the introduction of an Internet channel brings a signifi- cant increase to manufacturers＇ profits and reduces retailers＇ profits, leading to the channel conflict. Manufacturers＇ adopting product remanufacturing strategy can increase manufacturers＇ and retailers＇ profits; and ③in addition, price elasticity coefficient has an important effect on introducing an Intemet channel.
