目的 分析2006年—2020年我国护理本科生专业认同水平的变化趋势。 方法 检索中国知网、万方数据库、维普数据库和PubMed、Web of Science数据库，检索时限均从建库起至2022年5月，收集关于国内护理专业学生专业认同的相关调查研究，提取文献发表年份、调查年份、样本量、专业认同和各维度的得分，运用横断历史元分析对我国护理本科生的专业认同以及其不同维度随年份变化的特征进行分析。结果 年份对我国护理本科生的专业认识维度以及专业期望维度有预测作用（P<0.05），对专业认同以及专业情感、专业意志、专业价值观、专业技能4个维度没有预测作用。相较于2006年，护理本科生2020年的专业认识维度上升了0.831个标准差，上升幅度处于大效果量；专业期望维度下降了0.535个标准差，下降幅度处于中效果量。 结论 2006年—2020年我国护理本科生的专业认识趋向良好，但日后仍需关注护理专业学生的专业认同情况，提高其专业期望。
