中文摘要：

针对由2个生产商和1个零售商组成的供应链,研究生产商作为领导者时,零售商采用加成定价法且提供通用服务对参与方定价和服务决策的影响。结果表明：随着服务敏感系数的逐渐增大,产品的批发价、零售价相应提高。当产品价格弹性增大时,零售商降低服务水平,而当产品之间替代性减弱时,零售商提高服务水平。提供通用服务虽然导致零售商利润先增大后减小,但供应链中每个参与方的利润都比不提供服务时大。

英文摘要：

The influence of service cost of the retailer on the optimal price and the service decision are studied in a supply chain composed of two manufacturers each of whom makes a kind of product and a common retailer who adopts the strategy of markup pricing and provides the universal service. The results show that the wholesaling price and retailing price both increases with the service-related parameters increases. The service level is low when the sales of products are effected dramatically with the change of the price, but high about the two kinds of similar products. Although the profits of the retailer first increase and then decrease with the service from the retailer, the profits about everyone of the supply chain is more bigger than that without universal service.
