The embodiment of the invention provides a method for determining a high-speed railway operation safety index, and the method comprises the steps: determining a high-speed railway operation safety index based on a mobile equipment health index, a work safety index, a power supply fault index, and an electric service safety index and the weight ratio among all indexes, wherein the weight ratio among the indexes is determined as follows: establishing a judgment matrix F based on the size relationship between every two accident ratios corresponding to the indexes; if the F passes the consistencycheck, determining an analytic hierarchy process weight between the indexes based on the F; determining entropy values of the indexes corresponding to the indexes based on the N samples of the indexescorresponding to the indexes, and determining information entropy weights among the indexes based on the entropy values of the indexes corresponding to the indexes; and establishing a least square optimization method to combi
