Service-based Product Differentiation: one Mechanism of Service-enhancement

摘要本文以“制造业服务增强”研究为起源,在经典的地点差异化模型框架内,构建了服务延伸产品差异化的完全信息动态博弈模型:“同质化模型”和“附加服务的差异化模型”,并求取其均衡解,从经济学角度对“服务增强”的重要机制———服务延伸产品差异化以增强产品竞争力并获取价值进行了分析。模型构建和讨论表明:(1)服务能有效延伸产品差异化并增强产品竞争力,它提升了厂商价值和消费者剩余,是提高社会总福利的“双向增强”;(2)消费需求模式的变化是服务增强现象出现的关键因素,而厂商移动的边际成本对其采取差异化竞争战略有重要影响;(3)服务增强是一个动态过程,具有明显的行业差异性。 Based on theoretical framework of Hotelling differentiation model, this article developed two game-theory model to explore an important mechanism of service-enhancement in manufacturing firms, that is, service enhance the competence and value of product by extending product differentiation. This article found：（1） service is an efficient way to extend product differentiation, it not only enhances the competence and value of product but also promote consumer surplus; （2） change of consumer demand pattern is a key factor to lead to service enhancement; （3） service enhancement is an ence is evident. dynamic process and its inter-industry difference is evident.
