Once terrorist activities occur, they will bring major social risks and irreparable losses, which are a huge challenge for counter-terrorism operations (Jennifer & Louise, 2009; Pooja & Archana, 2021). There are great differences in the research contents of counter-terrorism threat risk assessment. From the perspective of the role attributes of research object, it can be divided into global risk assessment, fixed object risk assessment and active risk assessment (Scott, 2001; Novikov & Koshkin, 2019; Karl & John, 2008). The latter two are more focused and easy to quantify, and generally serve as the basis of global risk assessment. Due to the different objects of risk assessment, the methods adopted are also very different, resulting in great differences in the difficulty, effect and scope of application of the assessment.
