The application of smart contract solves the technical problem of individual differentiated pricing. Differentiated pricing, a new product in the field of platform economy dubbed as “big data-enabled price discrimination against existing customers”, is roughly summarized and completely denied. In this regard, it is of great necessity to clarify the connotation, sort by type and analyze the actual effect of differentiated pricing. To be specific, it is improper to deny the differentiated pricing model only with the formal appearance of conformity and the single concept about the protection of the value, which is consumer welfare. The protection of multiple value should be reiterated by the antitrust law. It is also needed to combine with the connotation of price discrimination in economics to re-examine the legal sense of price discrimination. The regulation of the differentiated pricing model demands comprehensive coherence of the market regulation law to ensure the accuracy of the lawapplied, and reflection on the concept of platform economy supervision. It is essential to adhere to the market-based solutions, build data opening rules and introduce the competition mechanism into differentiated pricing model.
