[Purpose/significance] Exploring the internal mechanism causing mobile users' social media fatigue behavior is conducive to enriching information behavior theory and constructing a reasonable service and management system for mobile social media fatigue users. [Method/process] The paper analyzes the causes and consequences of mobile social media fatigue, builds a mobile social media fatigue behavior mechanism model, and under the factorlinked data label mapping, based on the PAGE theory paradigm kernel of data-driven management decision-making concepts, proposes mobile users social media fatigue management and development strategies. [Result/conclusion] The causality of social media fatigue of mobile users is effectively analyzed, and the mechanism model constructed can provide theoretical and practical guidance for the research of user information behavior.
