摘　　要：目的 人口老龄化基本国情下,探讨老年人再就业与死亡风险的关联。方法 基于中国老年健康与家庭幸福调查数据(CLHLS 2008—2018),构建倾向性得分匹配和时依协变量Cox风险回归联合模型,探究老年人就业对死亡风险的影响。结果 退休老年人再就业能降低17.9%的死亡风险;亚组分析中高龄、低受教育水平、较差经济状况的老年人再就业能降低死亡风险;男性、女性再就业均能降低死亡风险,且不同性别群体再就业的健康效应差异不显著。结论 适当鼓励老年人再就业可以缓解劳动力市场,降低退休老年人死亡风险,促进健康老龄化战略目标实现。Objective To investigate the relationship between re-employment and mortality risk of the elderly under the basic national situation of population aging. Methods Based on the survey data of Chinese Longitudinal Healthy Longevity Survey (CLHLS 2008-2018), a joint model of propensity score matching and time-dependent Cox risk regression were constructed to explore the impact of elderly employment on the mortality risk. Results The re-employment of the retired elderly could reduce the mortality risk by 17.9%. In the subgroup analysis, the re-employment of the elderly with advanced age, low education level, and poor economic status could reduce the mortality risk, both in men and women with no significant difference in the health effects of re-employment among different gender groups. Conclusion It is recommended that properly encouraging the re-employment of the elderly can alleviate the pressure of labor market, reduce the mortality risk of the retired elderly, and promote the realization of the strategic goal of healthy aging.
