为了研究供应链中纵向成员信息共享及横向成员之间的需求信息泄露行为发生机理，针对服从伯川德竞争的替代产品，建立了由一个批发商与两个竞争型零售商（在位零售商和跟随零售商）组成的基本模型，探讨了批发商泄露与不泄露在位零售商产品定价信息时两个零售商的产品差别定价策略，分析了批发商的泄露行为选择机理。研究表明：当批发商泄露在位零售商定价信息时，零售商一定进行分离均衡定价；当在位零售商定价高于分离均衡高价格时，跟随零售商判断市场为高需求状态，反之为低；当在位零售商的产品定价位于最小泄露区间时，批发商一定泄露在位零售商的定价信息。
為瞭研究供應鏈中縱嚮成員信息共享及橫嚮成員之間的需求信息洩露行為髮生機理，針對服從伯川德競爭的替代產品，建立瞭由一箇批髮商與兩箇競爭型零售商（在位零售商和跟隨零售商）組成的基本模型，探討瞭批髮商洩露與不洩露在位零售商產品定價信息時兩箇零售商的產品差彆定價策略，分析瞭批髮商的洩露行為選擇機理。研究錶明：噹批髮商洩露在位零售商定價信息時，零售商一定進行分離均衡定價；噹在位零售商定價高于分離均衡高價格時，跟隨零售商判斷市場為高需求狀態，反之為低；噹在位零售商的產品定價位于最小洩露區間時，批髮商一定洩露在位零售商的定價信息。

In order to study information sharing between longitudinal members and horizontal members ′de-mand information leakage mechanism in a supply chain , a basic model consisting of one wholesaler and two competing retailers ( incumbent and entrant ) is established .The selling products are alternative and sub-ject to Bertrand competition .The differential pricing strategies of the two retailers are discussed under the conditions of information confidentiality and information leakage .The supplier′s choice mechanism is ana-lyzed .The results are as follows:Once the leakage occurs , the retailers will choose the separating equilib-rium price .The entrant can judge that the market is high when the incumbent′s price is higher than sepa-rating equilibrium price , and otherwise low in market demand .When the product pricing of the incumbent is at the minimum interval , the wholesaler will disclose the incumbent′s pricing information .
