生产商回收下包装尺寸决策研究

包装尺寸和价格对生产商的盈利能力有直接影响，包装价格的变化相对来说比较清晰和透明，但是包装尺寸的变化却不易被消费者察觉。针对一个由单一生产商、单一零售商和消费者组成的闭环供应链系统，通过刻画与包装尺寸和价格相关的需求函数，来研究包装尺寸对闭环供应链回收渠道的影响，并探讨生产商回收下最优的包装尺寸决策。研究结果表明：当单位尺寸生产成本增加时，企业应尽可能地提供小包装的产品；当大包装中最后一单位的消费量增加时，企业应适当减小大包装产品的包装尺寸；企业应根据自身情况与外部条件灵活选择包装尺寸策略。

Study on Decision-Making of Package Size Under Manufacturer Recovery

Packaging size and price have direct impacts on the profitability of manufacturers. The change in packaging price is relatively clear and transparent, while the change in packaging size is not easily detected by consumers. A closed-loop supply chain system composed of a single manufacturer, a single retailer and consumer was studied by describing the demand function related to packaging size and price. In order to make the optimal package sizes decisions, the influence of packaging size on the recovery channel of closed-loop supply chain was studied. The results show that: with the increase in the unit size production cost, the enterprise should supply the small package products as much as possible. When the consumption of the last unit in the large package increased, the enterprise should appropriately decrease the package size of the large package products. Enterprises should choose packaging size strategy flexibly according to their own conditions and external conditions.
