Abstract: In order to promote the development of safety culture and enhance national safety cultural quality, based on the definition of “Internet +”, a definition of “Internet + safety culture” was proposed from the perspective of safety culture construction. According to the six-occasion communication theory of information dissemination, a six-occasion safety culture propagation model of “Internet + safety culture” was built. And based on this, a model was proposed for “Internet + safety culture” construction which is guided by the Internet thinking, and a safety culture construction frame of “Internet + safety culture” was presented. Concrete optimization paths of safety culture construction in the context of “Internet +” were studied. The results show that the Internet users' group is the core part in safety culture propagation in the context of “Internet +”, and that the construction of safety culture should be optimized along four specific paths, such as improving the construction of safety culture websites, broadening network communication channels of safety culture, promoting the construction and innovation of safety cultural online industries and establishing capacity evaluation system for safety culture communication.

Key words: safety culture, Internet +, theory of six-occasion communication, construction frame, optimization paths
