Abstract: How to identify the causality in management negligence is a difficult problem in practice, and most of the existing theoretical solutions have drawbacks of vague standards, insufficient reasoning,etc. The reason is that existing solutions ignore the unique hazards of management negligence, and are limited to observing in an empirical manner whether the intervention factors are abnormal, and thus cannot satisfy the imputation needs in circumstances of management negligence. In comparison, by introducing the hazard actualization theory to solve this problem, not only can we make the judgment process clearer, but we can also explain the nature of causality more profoundly, which makes the introduced theory the most ideal path. In specific judgment making, it should first be considered whether the management negligence creates a physical hazard or a qualification hazard based on the nature of the management behavior. Secondly, it should be considered whether the hazard is actualized in the result of the constituent elements in a direct or indirect way in combination with the specific type of hazard. Through standardized and step-by-step investigations, causality in management negligence can be easily solved.
