The basic premise for the supervisory body to investigate duty crimes in accordance with the law is the rea-sonable determination of the scope of supervision,which not only involves the exercise of power boundaries of supervisory organs,but also pertains to the demarcation between the investigative powers for duty crimes and those for ordinary criminal cases,especially in the context of institutional reforms within the supervisory system.The existing jurisdictional standards of"identity centered"and"charge centered"are inappropriate due to a lack of precise understanding of the core character-istics of supervisory organs.The core function of the supervisory organs responsible for anti-corruption should be used as the benchmark for the scope of jurisdiction in the investigation of job-related crimes,and the objects and matters should be comprehensively evaluated.In operation,they should be carefully identified according to the path of"people and things".Due to the cross nature of the subject identity and behavioral matters in some cases between official and nonofficial duties,it is necessary to follow the legal logic starting point of the exercise of supervisory power norms,combined with the requirements of efficient anti-corruption practice with comprehensive of supervision,pay attention to the normative and re-lated review of"matter to person",carefully delineate the power boundary of supervisory organs in investigating official crimes,and clarify the practical confusion and disputes in supervisory jurisdiction.
