The invention provides a comprehensive evaluation method and system for drill bit application efficiency. The method comprises the following steps: constructing and standardizing an initial decision matrix based on the number and attributes of to-be-evaluated drill bits; determining a judgment matrix according to the importance degree of drill bit attributes, calculating the subjective weight of each attribute by using an analytic hierarchy process, and realizing dynamic optimization based on a consistency verification step; calculating objective weight of each attribute by using an entropy weight method; introducing an Euclidean distance function to solve a combination coefficient, and integrating the subjective weight and the objective weight to obtain a combination weight; and finally, calculating the distance between the combined weight calculation target and each absolute ideal solution, further calculating the relative closeness, and evaluating the application efficiency of the drill bit according to th
