Validity Of The Information Communication Of The Commercial Bank In Managing Its Operational Risk

There have been plenty of basic and empirical researches on the operational risk of the commercial bank, both at home and abroad. The research on the information communication validity of the commercial bank in managing its operational risk, which being new and scarce, is chosen as the object of this paper. The work is done mainly in three aspects.1. Tridimensional network structure of the commercial bank in managing its operational risk is constructed.By combing the mainstream structure and the physical network structure of the commercial bank; and a tridimensional network structure of the inner and the exterior information communication of the commercial bank in managing its operational risk is constructed. And by using the tridimensional network structure, the mechanism of the information communication in and out the commercial bank is established.2. The model of validity of the information communication in and out the commercial bank is built.The connection style of the inner and the exterior information communication network of the commercial bank is devised. And based on the tridimensional network structure, the accuracy and the timeliness of the information communication is defined, and two indexes of the timeliness entropy and the accuracy entropy of the information communication are built, which can be used to monitor the validity of the information communication of the commercial bank in managing the operational risk.3. The index of validity of the information communication in and out the commercial bank is devised, which is used in appraising the efficacy of the commercial bank in managing the operational risk in certain time interval, thus different measure should be taken for different caution level of the efficacy of the commercial bank in managing the operational risk.
