Abstract

We propose an analysis of platform competition based on the academic literature with a view towards competition policy. First, we discuss to which extent competition can emerge in digital markets and show which forms it can take. In particular, we underline the role of dynamics, but also of platform differentiation, consumers multi-homing and beliefs to allow competition in platform markets. Second, we analyze competition policy issues and discuss how rules designed for standard markets can perform in two-sided markets. We show that multi-sided externalities create new opportunities for anti-competitive conducts, often related to pricing and contractual imperfections.

平台经济学:竞争政策的理论指南

本文基于学术文献，从竞争政策的角度对平台竞争进行分析。首先，我们讨论了竞争可以在多大程度上出现在数字市场，并展示了竞争可以采取哪些形式。我们特别强调了动态的作用，但也强调了平台差异化、消费者多归属和允许平台市场竞争的信念。其次，我们分析竞争政策问题，并讨论为标准市场设计的规则如何在双边市场中发挥作用。我们表明，多边外部性为反竞争行为创造了新的机会，通常与定价和合同不完善有关。
