[Purpose/significance] This study aims to systematically explore the impact of the group effects of push pullfactors on individual digital hoarding behavior. [Method/process] Drawing on push-pull theory and the MOA framework, this study developed a research model encompassing multi-dimensional factors such as emotional attach⁃ment, fear of missing out, intolerance of uncertainty, technology empowerment, digital information characterization, and social impact. By combining Necessary Condition Analysis (NCA) and Fuzzy-Set Qualitative Comparative Analysis (fsQCA), this study identified the core pathways and grouping patterns influencing digital hoarding behaviors. [Result/conclusion] The formation of individual digital hoarding behavior is jointly influenced by push-pull factors, with three
main pathways identified: the pull-dominant opportunistic motivation type, the push-induced motivational stress type,and the push-pull synergistic capacity-supporting type. Accordingly, this study proposes promoting digital environ⁃ment governance through a synergistic approach encompassing technological regulation, cognitive adaptation, and emo⁃tional guidance, thereby achieving the dual objectives of individual psychological adjustment and information environ⁃ment optimization.
