Abstract: Regression models and threshold models are used to analyze the impact of occupational differentiation on residents' participation in sports. It is found that occupational differentiation has a positive impact on residents' participation in sports, with individual economic income and subjective physical health both playing a positive regulatory role, and the former's effect is weakening over time. The moderating effect of individual economic income on the relationship between occupational differentiation and sports participation exhibits a phased characteristic of "enhancement, constancy and weakening", while subjective physical health is manifested in two stages of moderating effect of "improving health" and "maintaining healthy". Regardless of the occupation of residents, in the process of "striving to earn money", attention should be paid to cultivating the "active health" awareness of low-income and high-income groups.
