价格歧视一直以来都是反垄断领域的重点研究对象，而平台经济作为数字经济时代背景下新的经济模式正在迅速发展，如何有效规制平台经济领域中的价格歧视行为成为了重要的研究课题。在经济学的研究领域中，价格歧视行为被认为是经营者在参与市场竞争的过程中采取的价格策略。在一定程度上，价格歧视行为能够起到促进市场竞争、提高经济效率的作用。但与之相对的，经营者对产品采取差异化定价的最终目的是为了从消费者身上获得更多的剩余价值，这不仅会损害消费者的利益，同时也会破坏整体市场正常的竞争环境。虽然我国反垄断法对价格歧视行为做出了相应的规定，但由于平台经济属于新兴产物，其特殊性、对现行反垄断规则的解释等因素都可能制约法律监管的效果。因此，有必要对平台经济领域的价格歧视行为进行研究和优化。本文通过对国内外价格歧视方面的文献资料进行收集、归纳、研究，并结合我国的平台经济发展现状，以期能够为我国平台经济领域价格歧视行为的反垄断规制提出完善建议。

全文由以下五部分组成：第一部分主要阐述了本文研究背景，国内外研究现状，研究思路和方法，创新和不足。第二部分详细介绍了平台经济及价格歧视的相关概念及特征。同时围绕平台经济的发展现状、在特殊领域内价格歧视行为的特殊性作出进一步论述，重点分析了规制平台经济领域价格歧视行为的必要性。第三部分剖析了平台经济领域价格歧视行为的反垄断规制现状及存在问题。主要包括传统价格歧视的反垄断规制规定以及平台经济领域价格歧视认定原则，分析平台经济领域认定价格歧视的困境。第四部分对国外平台经济领域价格歧视的立法现状进行概述，并对国外符合我国国情的相关制度经验进行借鉴。主要包括欧盟《通用数据保护条例》以及日本《关于数字平台与提供个人信息的消费者进行交易过程中滥用市场优势地位的指南》、美国《罗宾逊—帕特曼法》。第五部分是平台经济领域价格歧视行为的反垄断规制建议。结合国内对于价格歧视行为的反垄断规制研究，在我国现有法律制度的基础上，对于我国当前平台经济领域价格歧视的反垄断规制中存在的问题，提出具有针对性的建议。
