中文摘要：

通过研究收购价格对旧件回收和再制造的影响,在制造商、再制造商和回收商构成的供应链系统中,新品和再制造品分别在一级市场和二级市场上销售,且两类市场需求相互独立。根据旧件评估价值是否包含附加值,推导出旧件收购价格与评估价值、顾客返回意愿与旧件附加值、旧件回收量与收购价格之间的关系式。然后,就旧件评估价值不包含附加值和包含附加值两种情形的制造商、再制造商、回收商和系统利润进行比较。研究发现：在旧件定价时,考虑旧件附加值并确定合适的成本利润率有利于提高旧件回收量、供应链成员利润和系统利润。

英文摘要：

The influence of acquisition price on returning and remanufacturing is studied, in the supply chain system with manufacturer, remanufacturer and collector, new items and remanufactured items were sold in primary market and secondary market respectively, and the demands of two markets were independent. Based on whether assessed value of cores including value-added, the mathematical relations are derived respectively between acquisition prices and assessed values of cores, return willingness of customers and value-added of cores, return willingness of customers and assessed values of cores, return quantity and acquisition prices of cores. Then, profits of the manufacturer, the remanufacturer, the collector and the system are compared in cases where assessed value of cores includes value-added or not. The results show that when cores are priced, it favors the increase of core return quantity, members＇ profits of supply chain and the system profit to consider the value-added of cores and to determine the right profit to cost ratio.
