The study reviews research on juvenile delinquency and justice in China since 1990. The review covers three issues that have been studied in the publications: (1) the nature and scope of China's juvenile delinquency; (2) individual, group, and institutional factors and their roles in delinquency involvement; and (3) the development of China's juvenile justice. Because Hong Kong is a special region of China and has a different social, political, and legal system, the study reviews the publications on Hong Kong's juvenile delinquency and justice in a separate section. It summarizes the findings derived from the review, analyzes and discusses the limitations of the reviewed studies, and provides prospects for future research in the area.
