The invention relates to an office Word-based document automatic modularization and multi-terminal independent authority limit editing method. The method comprises the following operation steps: step1, editing a document editor: editing a document basic template, editing a user data template, associating a feature code of the data template in a region specified by the basic template, and settingthe region specified by the basic template as a cyclic region; 2, automatically generating a document: obtaining an edited document basic template, obtaining background user data, traversing the userdata according to a feature code in the document basic template to obtain a result set, and filling the result set; and step 3, carrying out multi-terminal independent permission editing: distributingdocument chapter permission, independently performing editing by each terminal, and synchronously generating a complete document by the server. According to the method, the template style is preset in the document editor, the format is directly applied mechanically during editing, the trouble of format unification is avoided, the files are distributed to multiple terminals in a blocking mode to be edited at the same time, and the management terminal receives tasks completed by all the blocks and can be directly combined into a complete document.
