The invention provides an air attack target dynamic threat assessment method based on combined empowerment and improved VIKOR. Comprising the following steps: determining an air attack target dynamic threat evaluation index, determining a threat membership degree of the evaluation index, determining an expert capability weight based on a grey correlation coefficient, determining an expert clustering weight based on a system clustering method, determining an expert final weight, determining an index subjective weight, and determining an index objective weight based on an improved entropy weight method. The final weight of the index is calculated through subjective and objective combination weighting, target threat assessment of VIKOR is improved based on the regret theory, and target dynamic threat assessment is carried out based on the time sequence weight. According to the method, the problems that the index weight determination of the existing air attack target threat assessment method is greatly influenced
