A DEA analysis based distribution network investment efficiency evaluation method is provided. The method comprises the following steps: S1, determining multiple decision-making units for distributionnetwork investment efficiency evaluation; S2, selecting input indicators and output indicators of the decision-making units for the distribution network investment efficiency evaluation; S3, using the clustering analysis method to classify the input indicators and output indicators of the decision-making units, and obtaining multiple sets of screened input indicators and output indicators; and S4, using a data envelopment analysis and evaluation model to evaluate the multiple decision-making units, and obtaining the relative efficiency indices of the multiple decision-making units. The methodprovided by the present invention has the following advantages that: the clustering analysis method is used to screen the distribution network investment evaluation indicators, treasonable input indicators and output indicato
