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.
