The invention discloses a communication system device and running mode analysis evaluation method. The method comprises the steps of automatically collecting data based on a basic resource library of a communication management system in a mode of establishing a special view, querying a partition table and optimizing sql; according to a query condition, screening out analysis data from the automatically collected data; according to the analysis data, calculating an operation and maintenance evaluation index in a power communication device and running mode evaluation model; and according to the analysis data and the calculated operation and maintenance evaluation index, generating an analysis evaluation report. According to the method, high-volume data of the communication system are automatically collected and the analysis evaluation report is automatically generated.
