基于消费者效用模型的耐用品垄断商回购与再制造决策研究

运用消费者效用模型，研究了二手市场条件下耐用品垄断商回购并进行再制造的两周期动态决策问题。研究得到，当耐用品的生产成本与再制造成本低于临界值时，耐用品垄断厂商才应该选择回购并进行再制造；再制造不仅可以对二手市场产生挤兑效应，而且可以获得市场增长效应，新耐用品成本越高，则挤兑效应与增长效应越明显；耐用品垄断厂商有提高消费者对再制造耐用品的认可程度与降低耐用品耐用度的激励。

Durables Monopoly’s Buy-back and Remanufacturing Decision Based on the Consumer’s Utility Model

Based on the consumer utility model, the monopoly's buy-back and remanufacturing decisions under the second-hand market are discussed in a two-period dynamic model. Several conclusions are obtained. First of all, only if the manufacturing cost and remanufacturing cost are lower than the critical values, the durable goods monopoly should choose the buy-back and remanufacturing strategy. Secondly, the remanufacturing strategy not only cannibalize sales of the second-hand market, but also lead to the market growth. Moreover, the higher the manufacturing cost is, the more obvious the cannibalization effect and growth effect are. The monopoly can gain more profits by increasing the consumer's willingness to pay for the remanufacturing durable goods and the remanufacturing cost savings.
