The invention discloses a method for ranking operation monitor business data of an electrical network enterprise. The method includes the first step of creating a data condition exponential model, the second step of obtaining the operation monitor business data of the electrical network enterprise, the third step of carrying out data quality analysis according to a quintile method, and the fourth step of ranking the operation monitor business data of the electrical network enterprise. The data application condition is introduced on the basis of the original data quality as a key measurement index for data condition exponents, the problem that the prior data management process focuses on quality but neglects application is solved, and the virtuous circle that the quality is prompted by application and the data are guaranteed through the quality is formed for enterprise data. The data condition exponents and sub-indexes of the enterprise are ranked according to the quintile method, limitation of manual sentimental ranking and simple number ranking is avoided, system usability is improved, and the method is of greater practical significance on data management.
