In order to obtain its own interests, the platform does not naturally assume the obligation of data opening. However, if the platform only maintains its own competitive advantage, and thus conducts unreasonable data blockade on other platforms, it will not only bring inconvenience to users, but also damage the market order. China’s regulation of data interoperability blockade mainly focuses on the Anti-monopoly Law and the Anti-Unfair Competition Law, and should follow the principle of optimizing the Anti-Monopoly Law in its specific application. In practice, the Anti-Monopoly Law has difficulties in regulating the interoperability blockade of data, limiting the anti-monopoly law enforcement of the data interoperability blockade of platforms, and the unclear law on the open obligation standards of Internet platforms. Therefore, it is necessary to refine the identification criteria for the abuse of dominant market position, break the traditional anti-monopoly regulation and analysis path, introduce the principle of necessary facilities, improve the level of anti-monopoly law enforcement in China, and establish a clear open standard.展开更多
