随着平台经济的发展与人工智能技术的深化，传统的价格歧视在新兴的市场形态下呈现出新的形式，即算法价格歧视。智能出行、餐饮外卖、电子商务等众多领域的平台都加入到算法价格歧视当中。然而算法价格歧视有可能破坏市场竞争，损害消费者权益，造成一定的现实危害。在价格歧视规制体制当中，反垄断法向来发挥着重要作用，因此有必要基于反垄断法的视角，对算法价格歧视行为是否具备违法性进行认定。然而，由于算法价格歧视具备许多不同的新特点，反垄断法界定传统价格歧视行为的标准，在适用于界定算法价格歧视时，面临重重困境。通过对当前反垄断法规制困境的探讨，结合国外对于价格歧视行为的规定，本文建议可以通过明确主体范围、优化歧视行为事实认定、明晰损害后果判断标准和明确“正当理由”认定标准，从而优化算法价格歧视的违法性认定。

With the development of the platform economy and the deepening of artificial intelligence technology, traditional price discrimination has taken on a new form in the emerging market shape, namely algorithmic price discrimination. Platforms in many fields such as smart travel, catering takeout, and e-commerce have joined in algorithmic price discrimination. However, algorithmic price discrimination may destroy market competition and harm consumers' rights and interests, causing certain harm. Antitrust law has always played an important role in the regulatory system of price discrimination, so it is necessary to recognize the illegality of algorithmic price discrimination from the perspective of antitrust law. However, since algorithmic price discrimination has many new and different characteristics, the criteria for defining traditional price discrimination in antitrust law are faced with many difficulties when applied to algorithmic price discrimination. Through the discussion of the current antitrust law regulatory dilemma, combined with foreign provisions on price discrimination. This paper suggests that the illegal determination of algorithmic price discrimination can be optimized by clarifying the scope of subjects, optimizing the factual determination of discriminatory acts, clarifying the criteria for judging the consequences of damages, and clarifying the criteria for determining the "justifiable reasons".
