The present invention relates to a method and system for determining the quality of an application based on user behaviors of application management. The method includes: 1) preprocessing data on user behaviors of application management to obtain a sequence of management behaviors as a training set; 2) extracting features of the user behaviors from the obtained sequence of management behaviors; 3) establishing a multi-dimensional independent variable space using the extracted behavior features, wherein each application in the training set is considered as a point in the space; training a model according to the space; and debugging to obtain optimal model parameters and a definite regression model; 4) arranging the data of the management behaviors of each application to be predicted according to step 1) and step 2), and then inputting the result into the regression model, wherein an output of the regression model is the result of the application quality determination. The present invention can effectively remove irrelevant features and exert the quality expression ability of relevant features, and can obtain more accurate results for evaluation of application quality.
