Platform antitrust in China

This article reviews the recent developments in digital platform antitrust in China. I first introduce the key players in China's platform industry, particularly those that have been frequently affected by recent antitrust events. I then provide a brief overview of economic theories that are often cited in think tank reports and official documents, including network externalities, hub-and-spoke collusion, and contestable markets. Finally, recent platform antitrust events in China are reviewed, including the introduction of platform antitrust guidelines and major antitrust cases.
