Abstract: In order to clarify the generation law of safety culture, and further enrich and improve the theories of safety culturology, this research is carried out to systematically study the generation mechanism of safety culture by using the methods of theoretical speculation and literature analysis from a comprehensive perspective of "macro-middle-micro sense". Firstly, the definition of safety culture generation was put forward, and six factors of it, such as human needs of safety, safety threats and responders, were extracted out. Then, five approaches like the united type, practical type and rational type and two kinds of power-spontaneous type and operational type were proposed. Finally, four expression forms, including the formal form, experience form and theoretical form were analyzed. The results show that the core mechanism of safety culture generation can be summed up as the "6-5-2-4" generation theory of safety culture, which includes generation factors, approaches, power and expression forms.

Key words: safety culturology, safety culture, safety threat, generation mechanism, "6-5-2-4"theory
