Abstract: Taking the viewpoint of scientific development on safety production as its guiding thought, first, the course of development, the current state and future trends as well as some typical cases of safety production (including safety manufac-turing) in China are analyzed and studied. Through a careful summary of its nature and characteristics, this paper elaborates the chronicity as well as the critical and strategic nature of safety production. Second, it analyzes the integrity and close organic connection between various factors of safety production in light of its functions, connotations and rule of development. The intrinsic link and non-symmetrical parabolic relationship between safety production and the level of social economic development are also further revealed, which provides a quan-titative model for understanding the optimization of safety pro-duction. Finally, it discusses the relevant sub-systems of the general safety production system and the scientific and techno-logical sub-systems of the sound safety cycle (I.e. scientific and technological sub-systems) , as well as breaks down the scien-tific and technological sub-systems into different stages and identifies some key issues, thus providing ideas for sound cycle of safety technology in safety production. This paper may serve as a reference to managers as well as scientists and technolo-gists involved in safety production.
