互联网背景下，电商平台经营者针对入驻商家实施“二选一”的行为日益增多，其与排他性交易的法律性质相似，判断其属于正常的商业竞争行为还是需要竞争法规制的垄断或不正当竞争行为，应当结合竞争法规范进行违法性判断。“二选一”行为可能违反《反垄断法》中的滥用市场支配地位行为；部分采取技术性手段实施的“二选一”可能违反《反不正当竞争法》第十二条；《电子商务法》作为新兴产业立法，第三十五条虽然不属于纯粹的竞争法规范，但也在客观上发挥着补充规制的作用，但需进一步明确具体的要件标准。

Under the background of Internet economy, e-commerce platform operators are increasingly implementing "One of two-choices" actions for resident businesses. The legal nature of those actions is similar to that of exclusive transactions. Judging whether they belong to normal commercial competition or illegal actions which require regulations shall be judged in accordance with competition law. The "One of Two-choices" action may violate Article 17 of the "Against Monopoly Law"; some that are implemented by technical means may violate Article 12 of the "Against-Unfair Competition Law"; As the legislation for emerging industries, although Article 35 of the "E-Commerce Law" is not a pure competition law regulation, it also plays a supplementary role objectively, but it is necessary to further clarify specific requirements standards.
