A Study on the Variability of Content Creator Vitality on Social Media Platforms — A Case Study of “Zhou Daye Doesn’t Accept Aging” and “Chushi and Sanjiu

Abstract

In the increasingly competitive landscape of short video platforms, content creators often face the dilemma of “going viral is easy, staying relevant is hard.” This reflects the inherent instability between platform traffic allocation mechanisms and users’ limited attention resources. This study focuses on two representative Douyin accounts, Zhou Daye Doesn’t Accept Aging and Chushi and Sanjiu, aiming to analyze the differences in their “creator vitality.” Using comment likes as the primary data source, the research applies methods such as high-frequency word analysis, sentiment polarity recognition, thematic concentration measurement, interaction intensity evaluation, and linguistic uniqueness modeling. Based on these, a quantitative framework for assessing creator vitality is constructed. Findings show that Zhou Daye Doesn’t Accept Aging fosters a comment section with more positive sentiment, clearer thematic focus, stronger engagement, and more creative language use. In contrast, Chushi and Sanjiu display signs of emotional detachment, topic diffusion, weak interaction, and formulaic expression. These results suggest that a creator’s vitality depends not only on the content itself but also on the depth of emotional investment and linguistic interaction from their audience. In conclusion, this study recommends the development of a “comment section health early-warning model” to help creators detect potential signs of decline and extend their active presence on the platform.
