Abstract: [Purpose/Significance] As scientific research achievements are disseminated on social media, they gradually attract public attention and discussion. Exploring public attitude towards scientific research achievements disseminated through social media, and seeking effective ways to strengthen scientific communication and enhance public scientific literacy, are crucial for improving the social impact of scientific research achievements. [Design/Methodology] The Public attitude towards scientific research achievements are calculated based on the number of likes, share, and the sentiment tendencies of comments on the posts related to these achievements. A public attitude model for scientific research achievements is constructed, and the differences in public attitude are analyzed from three aspects: scientific research achievements, blog posts, and the public. [Findings/Conclusion] An empirical analysis using Weibo data reveals that scientific research achievements on social media, especially those that receive widespread dissemination, often receive more negative and skeptical evaluations from the public. There is a weak negative correlation between the level of dissemination power of achievements and the positivity of public attitude; the public holds more positive attitudes towards applied scientific research achievements; the posts that clearly indicate authoritative sources, clarify background significance, mention identity information, have accurate and objective content, and present in a rich form are more likely to receive positive feedback from the public; public cognition and experience significantly influence their attitudes; and excessive or insufficient cues will weaken public trust and support. [Originality/Value] This study reveals differences in public attitude towards the scientific research achievements with different types and dissemination forms, and summarizes the content and dissemination characteristics of those research achievements that elicit positive public attitude. It provides references for enhancing public scientific literacy, scientific communication, and the social impact of scientific research achievements.
