通过分析2个零售商之间的竞争博弈，得出他们的均衡库存，研究了损失厌恶和产品替代率对零售商库存决策的影响。研究结果表明：存在替代品竞争的情况下，当缺货损失大于过量订货损失时，损失厌恶使得零售商库存和行业总库存增大；反之，损失厌恶使得零售商的库存和行业总库存减少；数值实验说明，当市场需求的分布不同时，产品替代率对零售商最优库存决策的影响不同，零售商在进行产品定位时，应考虑市场需求的分布。

This paper studies the loss-averse newsboy problem based on competition between sub- stitutable products. We first analyze the game between two competitive retailers, each of which is loss-averse. Then we obtain the equilibrium inventory level of them. Finally we develop the effect of loss-averse preference and product substitutability on the loss-averse retailer＇s inventory level. The re- sult shows that the inventory level of both the single retailer and the whole industry increase with the retailer＇s loss-averse effect when the underage loss is less than the overage loss. ; otherwise, the inven- tory level of both the single retailer and the whole industry decrease with the retailer＇s loss-averse preference. The numerical study shows that the effect of product substitutability on the retailer＇s in- ventory level is different when the demand distribution is different, the retailer should consider the de- mand distribution when deciding its product position.
