Abstract: 【Purpose/significance】This study analyzes and explores the influencing factors of Zhihu mention count from the perspec⁃ tives of mention subject and mention object, aiming to promote the development and application of altmetric research targeting local demand.【Method/process】The study collected data from 29 secondary Zhihu topics, identified academic papers mentioned by Zhihu from the data, obtained metadata of academic papers and utilized correlation analysis, principal component analysis, and linear regres⁃ sion analysis to reveal the impact of academic paper characteristics and Zhihu post characteristics on Zhihu mention count.【Result/ conclusion】(1)The influencing factors of Zhihu mention count can be divided into two categories: academic paper characteristics and Zhihu post characteristics; (2) The citation frequency of academic paper is significantly positively correlated with Zhihu mention count, while the length of title and the number of references have a weak negative impact on it; (3) Compared to the proportion of punctuation and the number of references, the length of content and the number of links of Zhihu post have a stronger positive impact on Zhihu mention count, while the number of images has a weak negative impact. These results provide useful references for a deeper under⁃ standing and application of Zhihu altmetric data.【Innovation/limitation】Exploratory research has been conducted on Zhihu, an impor⁃ tant Chinese altmetric data source. In the future, further consideration will be given to the correlation between time, discipline, author, and other relevant characteristics and Zhihu mention count.
