不同市场竞争环境下生产成本信息分享决策

考虑由一个制造商和两个竞争性的异质零售商组成的二级供应链,在外生批发价格的情形下,研究制造商在不同市场竞争环境下的生产成本信息分享策略:均分享、仅分享一个零售商和均不分享.研究发现,在零售商的成本估计值均大于真实生产成本的情形下,当市场竞争不激烈时,制造商的最优策略为均分享,否则,为均不分享.当存在零售商的成本估计值小于真实生产成本的情形下,制造商的信息分享策略与市场竞争程度和退货成本有关.随着退货成本的增加,当市场竞争程度非常激烈时,制造商越不愿意分享生产成本信息,否则,制造商越愿意分享生产成本信息.成本信息分享在市场竞争激烈或非常激烈的环境下能改进所有供应链成员的利润.

Production cost information sharing strategiesunder various market competition

In a supply chain consisting of a manufacturer and two heterogeneous retailers with price competition and exogenous wholesale price, we study the production cost information sharing strategies from the manufacturer's perspective in terms of sharing with both, one or none retailers. We find that, if the truthful production cost is less than both production cost estimation of retailers, when the market competition is weak, sharing with both retailers is optimal, and otherwise, no sharing is optimal. However, when the truthful production cost is larger than one of the production cost estimation of retailers, the manufacturer's optimal production cost sharing strategies rely on both market competition and return cost. With the increasing of return cost, when the market competition is very intensive, the manufacturer prefers to share with production cost information, and otherwise, the manufacturer prefers to not share with production cost information. More importantly, we find the production cost sharing can improve the profit of all members in the supply chain under very intensive or intensive market competition.
