Abstract: Considering the characteristics of durable goods can be used in multi-period, we construct a remanufacturing decision model for durable goods monopolist from the perspective of consumer utility. By using the stationary equilibrium analysis method, some conclusions are drawn. The existence of a second-hand market would reduce the cost threshold for durable goods monopolist to choose remanufacturing strategy, and raise the optimal pricing for new durable goods, and moreover, reduce the optimal pricing for remanufactured goods. The larger the value of new durable goods is, the lower the remanufacturing costs are, and the more influence a second-hand market has on the optimal decision for durable goods monopolist. At last, the theoretical results are tested by numerical analysis.

摘要： 考虑耐用品可多周期使用的特点,从消费者效用角度建立了无限周期中存在二手市场时耐用品垄断厂商再制造决策模型。运用稳态均衡分析方法得到,二手市场会降低耐用品垄断厂商选择再制造策略的成本临界值;提高再制造耐用品的最优定价、降低新耐用品的最优定价;新耐用品价值越高、再制造成本越低,二手市场对耐用品垄断厂商的最优决策影响越大。最后,通过数值分析验证了理论分析的结论。
