The invention relates to the technical field of electric power engineering, in particular to a subjective and objective combination weighted power distribution network operation state multi-level evaluation method. According to the invention, the power distribution subarea is divided into four levels including power distribution network switch equipment, a power distribution transformer, a power distribution line and a power distribution subarea, and meanwhile, a three-layer operation state evaluation index system is constructed, and indexes of each level are weighted by using a subjective andobjective combination weighting method, so that comprehensive evaluation of the multi-level operation state of the power distribution network is realized, and weak links of power distribution partitions can be identified according to key information indexes of the operation state.
