Abstract: This paper aims to explore the factors influencing the discontinuous usage behavior of mobile short-form video users, with the purpose of providing theoretical guidance for operators to develop effective user retention strategies and offering insights for deepening related studies. Based on the “Theory-Context-Methodology” (TCM) framework, the paper first systematically reviewed the research status of mobile short-form video users' discontinuous usage behavior, examining theoretical foundations, research contexts, and methodological approaches both domestically and internationally. Subsequently, it synthesized the influencing factors and mechanisms underlying this behavior by integrating the dual-factor (enabling-inhibiting) perspective, the information ecology perspective, and the S-O-R model.The present study reveals that the discontinuous usage behavior of mobile short-form video users is significantly influenced by enabling factors such as privacy concerns, information overload, system feature overload, and upward social comparison, as well as inhibiting factors including switching costs, information timeliness, platform usefulness, and social influence.
