Abstract: Since the theory of legal interest violation carries more practical significance to the construction of Chinas criminal law and criminal nomocracy， it is necessary that the basic concept that crime is a violation or threat of legal interests should be established and the essence of status crime should be interpreted as a violation of legal interests. Problems might arise from handling status crime in judicial practices in that Chinas criminal law does not specify status crime. A reasonable solution to such problems is introducing typological thinking， namely， the transformation from concept to classification. Meanwhile， it is suggested that the types of status crime in the general provisions of criminal law should be clarified and the typological regulations should be added to the provisions of status crime and its relevant criminal liabilities so as to guide the application of specific criminal law provisions， enhance the applicability of criminal legislation and eventually achieve the criminal nomocracy.

Key words: status crime, criminal essence, criminal liability
