研究基于CGSS2017数据，实证检验了体育锻炼对我国居民希望水平的影响效应，并深入分析了其影响机制。

Exploring the impact and mechanisms of physical exercise on hope levels among Chinese residents is essential for gaining a deeper understanding of the positive psychological effects of physical exercise. Furthermore， this research can serve as a valuable reference for fostering and enhancing hope， as well as promoting the development of a positive social mindset. Based on the CGSS 2017 data released in 2020， multiple linear regression， propensity score matching， and the KHB method were employed to investigate the impact and mechanisms of physical exercise on hope. The findings indicated that， compared to non-participation， engaging in physical exercise significantly increased the levels of hope among participants. Physical exercise can influence individuals’ levels of hope through three distinct mediating pathways： physical health， subjective wellbeing， and interpersonal interactions. Physical exercise can also influence individuals’ levels of hope through the combined effects of physical health， subjective well-being， and interpersonal interactions， with subjective well-being demonstrating the greatest mediating contribution， followed by physical health and interpersonal interactions in descending order of influence. Research indicates that active participation in physical exercise is essential for enhancing residents’ levels of hope and fostering a positive social mindset. We should fully implement the national fitness strategy and continue to promote the comprehensive development of fitness initiatives at the grassroots level.
