The invention discloses an electricity distribution park value evaluation method and device. The electricity distribution park value evaluation method comprises the following steps: acquiring basic information of a park; according to the basic information, establishing a first-level index and a second-level index for evaluating the value of the electricity distribution park; assigning a value to each secondary index; normalizing the secondary index values; using a principal component analysis method to obtain the comprehensive value and each first-level index value of the park; obtaining the comprehensive value and each primary index value of the park by using a weighted rank-sum ratio method; and combining the park value obtained by the principal component analysis method and the weightedrank-sum ratio method, and performing weighted average to obtain a final value evaluation result. According to the electricity distribution park value evaluation method, the social value of the electricity distribution park is accurately evaluated from multiple aspects, and the evaluation value of each first-level index of the park is calculated while the comprehensive value of the park is calculated, and the evaluation method is more detailed and detailed, and the index quantification difficulty is greatly reduced, and too high subjectivity is avoided.
