产品差异、转移成本和市场竞争

Competitive Markets with Product Difference and Switching Costs

文章通过在豪泰林空间差异模型的基础上结合转移成本构建的博弈模型,主要研究转移成本和产品差异的存在对于企业价格竞争和策略性行为的影响。文章发现纯策略价格均衡是否存在以及在位企业容纳还是遏制竞争对手的潜在进入,都依赖于转移成本相对于产品差异程度的大小。

This article examines the effect of product difference and switching costs on price competition and strategic behavior of firms. The game models are developed based on the Hotelling＇s model of spatial differentiation with switching costs. We get the conclusion that the relativity of switching costs and product difference determines whether pure strategic price equilibrium could exist or not. It also determines whether the incumbent could accommodate or deter the entry of potential entrants.
