In recent years, with the continuous development of digital economy, regulating the healthy development of platform economy has become an important issue. China's relevant government departments call for a clear adherence to the principles of “fair competition”, and for the strengthening of anti-monopoly and the establishment and improvement of market supervision to adapt to the development of the digital economy. In the process of anti-monopoly law enforcement, the relevant market definition is usually regarded as the logical starting point of analyzing the competitive behavior. Compared with traditional enterprises, platform enterprises have bilateral market characteristics such as “cross network externality” and “asymmetric price structure”, which face challenges in defining their relevant markets. This article first clear the bilateral market meaning, then discusses the platform enterprise bilateral market characteristics, and sort out the scholars in recent years about “define a single or multiple market” “assumed monopolist test is applicable”point of view, finally analyzed the “Sherpa's Abused Market Dominance” “Tangshan Renren Company v.Baidu Case” “Qihoo360 v.Tencent Case” three Chinese anti-monopoly law enforcement cases. The aim is to further discuss how to better combine the theoretical investigation and case analysis of qualitative and quantitative analysis to define the relevant market more accurately.
