Abstract: There are two problems in the research of negligent crimes in China’s competitive sports, one of which is the failure to analyze the types of such crimes, the other is the failure to provide detailed demonstration of crime or noncrime based on the analysis of the types. The criminal negligence in China’s competitive sports is divided into competition negligence behavior and supervisory negligence. Pure negligent injury in competitions is noncrime which is in line the modest and restrained principle in criminal law, meeting the condition of weakened responsibility ability. Injury behavior deriving from deliberate violation of sports rules is entitled to no weakened responsibility ability and should be punished.

Key words: criminal negligence, sports competition negligence, pure competition negligence, deliberately competition negligence, supervisory negligence
