Using 703 theses from 2013 to 2020 as research objects，and employing a mixed research method combining content analysis and semi—structured interviews，this study conducts an analysis of the topic selection and research methods in master’ s these in publishing studies. The findings of this research reveal an imbalance in the distribution of thesis formats and a low proportion of joint guidance. Furthermore，there is an excess of applied research but insufficient foundational research. The theoretical foundation of these theses is relatively weak，and the research perspectives are often constrained within narrow boundaries. The research methods employed show a trend towards diversification，however，the standardization and innovation in these methods still need further improvement. In the future，it is recommended to adopt a multidimensional assessment and joint guidance. Both theoretical research and practical publishing initiatives should be pursued simultaneously，emphasizing both standardization and

innovation in research methods.
