双边市场的理念自提出以来,自身的理论不断完善,具有不同于单边市场的新特征,如交叉网络外部性、价格非中性和市场的相互依赖性。这些特征对反垄断法中相关市场的界定方法如假定垄断者测试法的适用提出挑战。尽管同样是双边市场,不同类型的双边市场在适用反垄断法时存在不同特点。根据双边市场的类型来界定相关市场是一种比较好的思路。解决反垄断法中双边市场条件下相关商品市场的界定问题必须应该以双边市场的特性为基础,展开新的思考,同时要考虑不同类型双边市场的特点。 Since its introduction, the idea of ​​a bilateral market has continuously improved its own theory and has new characteristics that are different from unilateral markets, such as cross-network externalities, price non-neutrality and market interdependence. These features challenge the definition of the relevant market in the antitrust laws, such as the presumption of the application of the monopoly test method. Although also a bilateral market, different types of bilateral markets have different characteristics when applying antitrust law. According to the type of bilateral markets to define the relevant market is a better idea. To solve the definition of the relevant commodity market under the bilateral market conditions in the antitrust law, we must start with new thinking based on the characteristics of the bilateral markets, taking into account the characteristics of different types of bilateral markets.
