The invention discloses a method and a system for monitoring the material supplies of an electric power enterprise. The method comprises: according to a preset dynamic monitoring model, acquiring the material information of the entire material supply process of an electric power enterprise in real time; based on the acquired material information, calculating the monitoring index and the performance index corresponding to the dynamic monitoring model; and according to the calculated monitoring index and the performance index, generating a visual report table for a user to carry out the dynamic tracking and monitoring for the entire material supply process. The method of the invention performs monitoring to an entire material supply process through the monitoring index and the performance index, and then, outputs a visual report table so that the information concerning the entire material supply process becomes obvious to all, therefore, increasing the management efficiency for the material supplies of the electric power enterprise. In addition, through the full-process monitoring to the electric material supplies, the cooperation and coordination between the electric power corporation and its unit companies at various levels are strengthened, which vigorously improves the smart supply chain for electric materials, reduces the communication cost and raises the efficiency of the enterprise.
