Personal information protection involves many legal departments，among which administrative law enforcement is an important mechanism for personal information protection. The current legislation，such as Cyber Security Law，Consumer Rights and Interests Protection Law，and Personal Information Protection Law （Draft），which has been published by the Standing Committee of the National People’s Congress，have made provisions on the administrative law enforcement mechanism of personal information protection. However，there are many problems in the existing norms，such as unclear law enforcement system，unclear scope of law enforcement，further refinement of the conditions and procedures for the exercise of law enforcement measures，failure to achieve gradient correspondence between illegal acts and legal liabilities，and so on. In the future，we should further clarify the administrative law enforcement system and power distribution of personal information protection，improve the law enforcement procedure，and optimize the setting of administrative legal responsibility.
