A Review of Anti-monopoly Cases in China's Platform Economy After 2021

With the rapid development of the digital economy, the monopoly problem of China's platform economy has become increasingly prominent. Since the implementation of the "Anti-Monopoly Guidelines for the Platform Economy" in 2021, China's anti-monopoly law enforcement agencies have investigated and dealt with multiple cases of platform economy enterprises abusing their dominant market positions, including typical cases such as Alibaba, Meituan, China National Knowledge Infrastructure (CNKI), and Ningbo Senpu Information. This article, through the analysis of these cases, discovers that the current law enforcement has problems such as insufficient fines, unclear scope of penalties, and the absence of supervision over foreign-funded enterprises. Furthermore, the post-event supervision model is difficult to effectively prevent monopolistic behaviors and may harm the interests of consumers. To this end, this article suggests raising the upper limit of fines, optimizing the calculation standards of penalties, strengthening the supervision of foreign-funded enterprises, and promoting full-process supervision to enhance the deterrent effect of the law. In the future, it is necessary to further improve the anti-monopoly mechanism for the platform economy and balance the efficiency of law enforcement with market vitality.
