Embodiments of the invention disclose a permission control method and apparatus for a mobile terminal, and the mobile terminal. The method comprises the steps of receiving a first operation system command, wherein the first operation system command is an operation system command on acquisition of a system permission of the mobile terminal; obtaining preset environment variable information according to the first operation system command, wherein the preset environment variable information contains a plurality of file directories; reading corresponding files in sequence according to the file directories; and when the read first file is a preset administrator user switching file, stopping the execution of the first operation system command. According to the method, the apparatus and the mobile terminal provided by the embodiments of the invention, the corresponding file in the first file directory of the preset environment variable information is set as the preset administrator user switching file, and when the preset administrator user switching file is read, the operation of obtaining the system permission of the mobile terminal is refused to be performed, so that unnecessary terminal security threat for a user is prevented, and the user privacy secrecy and the user information security are greatly improved.
