[Purpose/significance] In recent years, the research in the field of Emergency Intelligence (EI) has been widely concerned by the academic circle and has made remarkable achievements, which has laid a solid foundation for the discipline construction of EI science. At present, the basic theoretical system of EI science has not been estab? lished. Therefore, it is the right time to discuss the discipline construction of EI science. [Method/process] On the dis? ciplinary construction level, based on the theory of emergency management and intelligence science, this article dis? cussed and analyzed six basic issues of EI science, including the definition, connotation, nature, research object, re? search contents and methods of the discipline. [Result/conclusion] The results show that EI science has the conditions to become an independent discipline. EI science is a interdisciplinary application discipline which studies and discuss? es the nature, function, structure, generation, transmission and utilization of EI, and provides intelligence service for emergency management. It is a new branch of intelligence science and emergency management.
