Data sharing method and multisystem terminal

The invention provides a data sharing method and a multisystem terminal. The data sharing method includes that one or more than one system imports shared data corresponding to shared data types into a shared space; after a current system detects a data invoking request, the shared data corresponding to the data invoking request is read in the shared space. By using the data sharing method and the multisystem terminal, the one or the more than one system imports the shared data corresponding to the shared data types into the shared space, the shared data corresponding to the data invoking request is read from the shared space for alternative use of a user after the current system detects the data invoking request in use, and then data sharing among the systems is achieved on the premise that all the systems can not directly communicate, and use experience of the user is enhanced.
