The invention discloses a dynamic financial network monitoring analytical method, comprising the following steps especially: (1) building a dynamic financial network model, the flowing conversion process from a financial database to a directional weighted graph is included; (2) computing weight of attribute: by analyzing case database of doubtful transaction, doubtful degree weight of the attribute is obtained by statistical leaning, the weight of attribute is for short; (3) dynamically monitoring analysis of the doubtful degree of account and transaction is carried out; by comprehensively considering the common effect of multiple attributes of account and transaction, and the effect of the last time slice on the current time slice, the doubtful degree of account and transaction along with time is dynamically monitored; (4) updating the weight of attribute: when a new doubtful transaction appears, the case database of doubtful transaction and the weight of attribute are updated; (5) incremental updating the d
