As a scholarly discipline, criminology in China is growing in stature, maturity and utility. In the short thirty years since 1979, China has successfully established criminology as a scientifi c fi eld of study with well-defi ned subjects, recognised scholars and copious research/publications. To date, there are very few systematic and comprehensive studies of criminology (in English language) as an emerging and important fi eld of academic discipline in China. As a result, we know very little about its focus and scope; direction and trend; theories and fi ndings; and problems and issues. This is a fi rst attempt to do so. The article (in two parts, published separately) investigates into: 'Literature on law, crime and punishment in China', 'The idea of crime (Fanzui)', 'Traditional thinking of crime and punishment in imperial China', 'Nature, structure and development of criminology', 'Contemporary theories on crime and punishment' and 'Fundamental issues and challenges' facing criminological research in China.Criminology research in the 21st Century should be conducted under the guidance of Marxism, thought of Mao Zedong and theory of Deng Xiaoping. It should start with the actual conditions of our nation and insist on combing theory and reality. It should contribute to construction of socialist economy and serve comprehensive social control and administration. It should contribute to 'permanent order and lasting peace' and people's peaceful living and happy work.
