Since it was first proposed by Professor Liu Renwen in 2003, “multidimensional criminal law science” has become a symbolic concept of Chinese criminal law. As a research concept and method, it adheres to systematic and relational thinking, and has had a positive impact in expanding the horizon of criminal law research, integrating criminal law doctrine and social science criminal law, responding to local criminal law practice, and giving Chinese criminal law an international discourse power. This book was first published in 2018 as part of the book series "Library of the Chinese Academy of Social Sciences". This revised edition has made some adjustments to some contents, incorporated the author's latest thinking on "multidimensional criminal law", and advanced towards the three major goals of constructing "multidimensional criminal law", "relational criminal law", and "systematic criminal law".
