The method comprises the following steps: acquiring the current networking mode and habitual networking mode of a user terminal; acquiring the downloading networking attribute and running networking attribute of an application to be recommended; and recommending the application to be recommended of which the downloading networking attribute matches the current networking mode of the user terminal and the running networking attribute matches the habitual networking mode of the user terminal to the user terminal. According to the method, applications not adapting to the application environment of a user terminal are excluded, and only screened applications adapting to the application environment of the user terminal are recommended to the user terminal. The method can ensure that users can download recommended applications normally and that user terminals can run recommended applications normally. Therefore, users can get good user experience.
