摘要
我国在加入WTO后,一些重要的服务领域面临着全面对外开放。由于转换成本的存在,使得该领域中本来在购买前功能相近的同质商品或服务,在购买后成为异质的商品。企业因而拥有相对于消费者的事后垄断的权力。为此,企业有动机在初期采取战略行为吸引消费者。这既缓和了后续阶段的企业间竞争,也在整体上将该行业的产品价格维持较高水平。它可能会降低社会效率和消费者福利。文章通过分析企业间在同质商品市场竞争的市场效果和福利后果,为在我国该领域反垄断立法提供了理论解释。
After entering WTO, some key industries with switching costs in China will face competition from abroad. Switching costs turn the homogeneous products ex-anti into heterogeneous ex-post when they are bought. Firms thus gain the ex-post monopolistic position. Therefore, firms have incentives to attract consumers strategically in order to soften competition afterwards, hence may maintain higher prices. This may lower the social efficiency and especially consumers＇ welfare. We provide a theoretic foundation for Antitrust Legislation in this filed in tween firms in markets of homogeneous China by analyzing competition beproducts.
