摘　　要：本文基于2016年中国老年社会追踪调查数据(CLASS),运用回归模型分析法、工具变量法及倾向得分匹配法,探讨体育锻炼对老年人生命质量的影响。研究发现:(1)体育锻炼会显著提升老年人的生命质量评分的0.123个标准分,降低老年人生命质量不良倾向2.5个百分点;(2)通过工具变量法和准实验的倾向得分匹配法解决内生性问题后,结果依然稳健;(3)体育锻炼对老年人生命质量的影响在不同年龄、受教育程度及经济收入之间存在显著差异。结论:体育锻炼会对受教育程度高、经济水平高的老年人生命质量有显著正向预测作用,显著降低生命质量不良倾向概率。This empirical study,based on the 2016 China Longitudinal Aging Social Survey(CLASS) data,examines the impact of physical exercise on the quality of life among elderly individuals.Using baseline regression,instrumental variable methods,and quasi-experimental propensity score matching,the findings of this studyindicate the following:(i) Physical exercise significantly improves the quality of life score for elderly individuals by 0.123 standard deviations and reduces the likelihood of poor quality of life by 2.5 percentage points.(ii) The robustness of the results is confirmed after addressing endogeneity issues through instrumental variable methods and quasi-experimental propensity score matching.(iii) The influence of physical exercise on the quality of life among elderly individuals varies significantly across different age groups,educational levels,and income levels.In conclusion,physical exercise has a positive and significant predictive effect on the quality of life among elderly individuals with higher education and income,effectively reducing the probability of poor quality of life.
