As platform economy grows,problems regarding the wild growth of digital platforms appear and cry for change and reform of platform supervisionBased on the theory of new institutionalism and supervision potential,this article analyzes the platform regulatory paradigm,and points out the dilemmas confronting the platform regulatory paradigm,including its difficulty in integrating multiple domains,identifying the regulatory objects,and defining the boundary of regulatory behavior and the regulatory powerIn considering such issues as the legal rights of the supervised subjects,the hierarchy of the supervision objectives,and the behavioral boundary in the process of supervision and its acceptability,this article argues that the platform supervision needs to be systematically reconstructed from the aspects of supervision concept,principle,and paradigm to build an integrated platform of supervision paradigm based on the domain stratification,subject classification,and target classification.
