The invention belongs to the technical field of
risk assessment, and discloses a
risk assessment method based on digital economy. The method comprises the following specific steps: S1, cross-
modal data federal acquisition; s2,
risk factor dynamic deconstruction; s3, dynamic modeling of game theory enabling is carried out; s4, generating a real-time risk thermodynamic diagram; s5, an edge
intelligent decision center; s6, dynamic
knowledge graph evolution; and S7, sandbox
verification and anti-fact deduction are carried out. According to the method, all-around innovation is brought to risk management and control, first,
data processing is performed, block chains, 5G and NLP technologies are utilized, multi-
source data are collected, public opinions are insighted, privacy compliance is guaranteed based on federal learning, and a safety footstone is built, and second, market strategies are provided, and by means of
reinforcement learning, Monte Carlo deduction and a
quantum annealing
algorithm, subject behaviors are simulated, policy
impact is pre-estimated, and a model is optimized, so that risk management and control are realized. And thirdly,
knowledge application, leading-edge technology labeling new risk
database establishment, federal learning optimization atlas and enhancement of practical operation to cope with complex risks are realized.
