The invention discloses an operation efficiency evaluation method and device applied to a multi-terminal flexible DC power grid. The method comprises the following steps: constructing a hierarchical evaluation index model based on topological characteristics of the multi-terminal flexible DC power grid; the model comprises a plurality of first-level indexes used for representing the operation efficiency of the power grid, and each first-level index comprises at least one second-level index used for representing a bottom-layer operation scheme; calculating a first-level weight value of each first-level index by adopting an analytic hierarchy process; generating a data set corresponding to each secondary index according to the operation data of the power grid, and constructing a data matrix; calculating a second-level weight value of each second-level index by adopting an entropy weight method; and generating a comprehensive weight value of each second-level index based on the first-level weight value and the s
