Abstract:In order to further improve the safety science system, promote the research and application of safety information, the discipline construction of safety information economics was carried out. Firstly, based on the basic theory of safety information, safety economics and information economics, the definition of safety information economics was refined, and its connotation was given; then, the theoretical basis of the safety information economics was discussed and the research content was summarized; research methods of safety information economics were summarized from 5 aspects, the research procedures of safety information economics were proposed and a detailed explanation was given. Finally, the prospect of safety information economics from three aspects was prospected. The results show that the construction of safety information economics has a solid theoretical foundation and a wide range of application prospects, and can be used as a subordinate discipline in safety informatics and safety economics in theory. In practice, it can be used for optimal allocation of enterprise safety resources, safety management and risk decision-making.
