Abstract:     The digital age is witnessing the criminology research theme evolving from“cities attracting crimes”to“network attracting crimes”, in which digital technology and digital platform have become brandnew theoretical elements. The mode of platform governance of crimes is catching increasing attention, for which the gatekeeper rule has provided systematic and institutional basis. In overseas theoretical circle, digital criminology was put forward as a distinctive academic label, and it has become the theme of the times to reconstruct the order of digital society with the assistance of criminology. In China, digital criminology is also booming, following such paradigms as the system theory based on platform ecosystem, the information theory based on online control, and the cybernetic based on gatekeeper regulation. Getting out of the aphasia dilemma that traditional criminological theories are confronted with in explaining new types of crimes, digital criminology has become the most dynamic research direction. In the future, it should pay more attention to such important theoretical issues as perceptions of new types of crimes and underground cyber industry, the inheritance and development of traditional criminology, the application of gatekeeper regulation and its problems, and the value balance of platform governance.

Key words: digital criminology, digital society, new cybercrime, platform governance, gatekeeper regulation
