Abstract：This study aims to explore the relationship between self ⁃ efficacy and physical activity among
school ⁃ aged children，along with the mediating role of exercise identity by utilizing the Physical Activity
Questionnaire for Children（PAQ⁃C），General Self⁃Efficacy Scale（GSES）and Exercise Identity Scale（EIS）to
investigate 3rd to 6th grade students of two primary schools in Nantong City，Jiangsu Province and Pingliang
City，Gansu Province. The results showed that physical activity score was higher in males，younger students，
non⁃only⁃child，and students from the western region. There was a positive correlation between self⁃efficacy and
physical activity levels. The exercise identity played a partial mediating role between self⁃efficacy and physical
activity，accounting for 59.3% . This study partially explains the intrinsic mechanism between children and
adolescents’self⁃efficacy and physical activity，providing a theoretical and practical basis for physical activity
intervention among children and adolescents.
Key words：self⁃efficacy；physical activity；exercise identity；mediating effect；school⁃age children
