短视频时代大学生媒介素养影响因素研究——基于PLS-SEM的实证分析
短视频平台已成为大学生日常媒介接触的核心渠道，其算法推荐、碎片化传播等特性深刻影响着用户的媒介素养。本研究基于使用与满足理论、媒介依赖理论及算法素养框架，构建“使用动机—信息接触—算法感知—使用行为—素养能力”的影响路径模型，采用偏最小二乘结构方程模型（PLSSEM）对118份大学生问卷进行分析。结果显示：短视频使用动机（β=0.497）与算法推荐感知（β=0.190）对媒介使用行为有显著正向影响，而信息接触特征影响不显著（β=0.055）；媒介使用行为显著提升批判性思维（β=0.439）、媒介素养水平（β=0.493）和理性表达（β=0.409）。研究揭示了“动机驱动行为、行为塑造素养”的核心机制，为高校在算法环境下开展精准媒介素养教育提供了理论依据。
