The invention provides an evaluation method for the development of prefecture-level electric networks. The evaluation method comprises the following steps: determining a criterion layer of the developmental research of the prefecture-level electric networks; for the criterion layer of the developmental research of each prefecture-level electric network, determining at least two first-class evaluating indicators and weight coefficients thereof; for each first-class evaluating indicator, determining at least two second-class evaluating indicators and weight coefficients thereof; for each first-class evaluating indicator, based on a fuzzy theory, computing a second-class evaluation result; based on the second-class evaluation results corresponding to all first-class evaluating indicators, obtaining the first-class evaluation results; for the criterion layers of the developmental research of the prefecture-level electric networks, obtaining the first-class evaluation results to be used as the evaluation results of the development of the prefecture-level electric networks; utilizing a preset judging set, judging and analyzing the evaluation results of the development of the prefecture-level electric networks. The evaluation method disclosed by the invention can evaluate the development of the electric networks in the round, points out the links which need to be strengthened in the development of the electric networks, provides a basis for a management decision, and promotes the health and high-efficient development of the prefecture-level electric networks.
