现实垄断竞争市场中的“最适差异化空间”

Chamberlain’s ‘The Most Suitable Space of Alienation’ in the Realistic Monopoly Competence Market

张伯伦有关在垄断竞争市场厂商短期可获得超额利润,长期转而获得平均利润的论断,不仅可运用霍特林模型证伪,而且遭遇波特等管理学家的质疑与挑战。在现实的垄断竞争市场中,有可能存在由"最适市场细分度"、"最适差异偏好度"、"最适产品生命周期"、"最适固定费用"、"最适信息对称度"、"最适市场集中度"共同约束形成的"最适差异化空间"。在这一特殊空间内,厂商有可能长期稳定地获得超额利润。

According to Chamberlain’s theory of monopolistic competition,manufacturers ’ excess profits received in short term will be converted into average profits in the long run,which can not be only falsified by using Hotelling’s Model but also has been challenged by Porter and other management theorists.In real economic life,there may exist an optimal differentiated space subjected to the optimal market segmentation,the optimal difference preference,the optimal product life cycle,the optimal fixed costs,the optimal information symmetry,and the optimal market concentration.In this particular space,manufacturers can have long-term excess profits consistently.
