Abstract: By sorting out the data sharing mode of open access （OA） journals in China,the copyright protection mode was explored to provide reference for the construction of OA publishing mode with Chinese characteristics. 335 Chinese OA journals were selected from the DOAJ database,and the data sharing mode was analyzed by literature research,data statistical analysis and other methods,so as to extract copyright protection strategies that meet the development needs of Chinese OA journals. At present,the OA journals in China mainly adopt the Creative Commons Attribution license （CC-BY）,and the mode of co-publishing by the organizer,such as the editorial office,the publishing house and the publisher leads to the disputes and problems concerning the distribution of benefits and the ownership of rights among the author,the domestic organizer and the publisher. Chinese OA journals can strengthen and improve copyright protection from the aspects of clarifying the subject of the agreement,improving the division of the rights and interests of all parties,introducing supervision,open access data warehousing,and localization construction of publishing platforms.
