Abstract:A questionnaire survey was conducted on 594 physical education teachers in compulsory education based on the JD-R theory, and the structural equation model was also used to test the path hypothesis of job demands, job resources, and psychological capital on work investment, and likewise,the multi-group analysis was also used to explore the moderating effect of various demographic variables here. The results showed that since the implementation of the " double reduction " policy, the job demands of physical education teachers in compulsory education have increased, but the job resources and work engagement have decreased; the job demands have a positive impact on work engagement, and job resources also positively predict work engagement; the psychological capital have played a partial mediating role between job resources and work engagement; the moderating effect of gender, region and school type is not significant, while age, grade, marital status and educational background could significantly moderate the mediating effect of psychological capital between job resources and work engagement. Based on these above, the study holds that according to the different demographic characteristics of physical education teachers, schools should focus on increasing the job resources such as the work significance and hardware conditions of physical education teachers while appropriately improving the job demands, so as to improve the level of psychological capital and then to promote the formation of positive work engagement among them.
