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.
Considering a two-level supply chain consisting of one manufacturer and two competitive heterogeneous retailers, under the condition of exogenous wholesale prices, we study the manufacturer’s information sharing strategy of production cost under different competition environment: share equally, only Share a retailer and do not share.The study found that in the retailer’s cost estimates are greater than the real cost of production in the case of market competition is not intense, the manufacturer’s optimal strategy for sharing, otherwise, are not Sharing.When the retailer’s cost estimate is less than the real cost of production, the manufacturer’s information sharing strategy is related to the degree of market competition and the cost of return.With the increase of return cost, when the degree of market competition is very intense, the manufacturer The less willing they are to share production cost information, the more they are willing to share manufacturing cost information Cost information sharing improves the profitability of all supply chain members in highly competitive or highly competitive markets.
