Recently, Professor Zhi Zhenfeng, a research fellow at CASS Law Institute, was interviewed by CGTN (China Global Television Network) Program China 24 on big data and price discrimination. In the interview, Professor Zhi pointed out that some platforms have collected a huge amount of people’s personal information and use artificial intelligence and algorism to personalize prices for a few people. This practice may constitute price discrimination, which is a violation of Consumer Rights Law. Although there are many laws protecting personal information, there is no specific law in this regard. This gives some fraudulent sellers the opportunity to personalize prices. The government has already identified this problem and taking measures to deal with it.
