Аннотация

This article examines the pressing issues of antimonopoly regulation concerning the use of Big Data in e-commerce. The author provides a detailed analysis of how the processing and control of large data volumes can lead to market distortion, including the creation of entry barriers for new market participants, personalized pricing, algorithmic collusion, and self- preferencing by platforms in favor of their own products. The study offers a comparative analysis of antitrust approaches in the European Union, the United States, and China based on specific cases and precedents (Amazon, Google, Alibaba). Special attention is paid to the legislation of theRepublic of Uzbekistan, particularly the new Law “On Competition” (№. LRU- 850), which, for the first time, includes specific provisions regarding digital platforms and the use of Big Data. Based on international experience, recommendations are formulated for the furtherimprovement ofnational antimonopoly regulation inthecontext ofthedigital economy.
