基于Hotelling模型的双寡头零售商服务策略选择研究

A Research on Service Strategy Selection of Duopoly Retailers Based on Hotelling Model

针对两个传统零售商组成的双寡头市场,考虑其中一个零售商选择增加服务的提供,研究该零售商采取何种服务策略的问题。基于Hotelling模型构建在单个零售商采取收费提供服务策略和免费提供服务策略两种模式下的零售商决策模型,得出零售商的最优利润、最优价格以及零售商增加服务的效果,并比较两个零售商在不同模式下的最优利润和最优价格。算例分析验证结果表明,无论是采取收费提供服务策略还是免费提供服务策略,增加服务的零售商都可以获得比其不增加服务时更高的利润;当收费提供服务的价格在较低范围内时,零售商采取收费提供服务策略更优;当收费提供服务的价格较高范围内时,零售商采取免费提供服务策略更优。

Aiming at the duopoly market composed of two traditional retailers,a case that one of the retailers chooses to increase service provision is considered,and what kind of service strategy the retailer adopts is studied.Based on the Hotelling model,a retailer's decision-making model is constructed under the two modes of a single retailer adopting a charging service strategy and a free service strategy to obtain the retailer's optimal profit,optimal price and the effect of the retailer's increased service,and the optimal profit and optimal price of two retailers under different modes are compared.Finally,a numerical example analysis and verification show that whether it is a strategy of providing a service for a fee or a strategy of providing a service for free,the retailer who increases the service can obtain higher profits than if it does not increase the service.When the price of charging services is within a lower range,it is better for retailers to adopt a charging service strategy;when the price of charging services is within a higher range,it is better for retailers to adopt a free service strategy.
