To address aging and its associated social risks, the World Health Organization proposed an "active aging" policy framework in 2002, highlighting "health, participation, and security" as the three pillars for enhancing quality of life in old age. Extensive research has shown that public pensions, as a state-implemented social security measure, can effectively improve the health and well-being of older adults. However, existing studies have not sufficiently examined the causal impact of public pensions on social participation among older adults, such as community volunteering.
Using data from the China Longitudinal Aging Social Survey in 2018, this article employs propensity score matching (PSM) and control function (CF) approaches to empirically examine the impact of the Urban and Rural Resident Social Pension (URRSP) on the participation of older adults in community volunteering. Specifically, we investigate whether this relationship varies across social groups.
Empirical results indicate that, compared to uninsured older adults, those enrolled in the pension program show a significantly lower likelihood and frequency of volunteering. This finding is robust after controlling for observable and unobservable characteristics, thus supporting the crowding-out hypothesis. Furthermore, heterogeneity analysis reveals that this crowding-out effect is more pronounced among older adults with higher socioeconomic status, such as those living in urban areas, with higher education, higher income, and better health. In other words, the limited benefits provided by the URRSP not only fail to offer financial support for volunteering, but also significantly reduce the willingness and level of volunteering among those with higher socioeconomic status.
The above findings confirm the crowding-out hypothesis, suggesting that in developing countries with underdeveloped and stratified social security systems, state-led public pensions may crowd out older adults' participation in volunteer activities that are altruism and mutual support.
为应对老龄化及其相关社会风险,世界卫生组织于2002年提出了“积极老龄化”政策框架,强调“健康、参与和保障”是提高老年生活质量的三大支柱。大量研究表明,公共养老金作为国家实施的社会保障措施,能够有效改善老年人的健康和福祉。然而,现有研究尚未充分考察公共养老金对老年人社会参与(如社区志愿服务)的因果影响。
本文利用2018年中国老年社会追踪调查数据,采用倾向得分匹配法(PSM)和控制函数法(CF),实证检验城乡居民社会养老金(URRSP)对老年人参与社区志愿服务的影响。具体而言,我们考察这种关系在不同社会群体中是否存在差异。
实证结果表明,与未参保的老年人相比,参加养老金计划的老年人参与志愿服务的可能性和频率显著更低。在控制了可观测和不可观测特征后,这一发现依然稳健,从而支持了挤出效应假说。此外,异质性分析表明,这种挤出效应在社会经济地位较高的老年人中更为明显,例如居住在城市地区、受过高等教育、收入较高且健康状况较好的老年人。换言之,城乡居民社会养老金提供的有限福利不仅未能为志愿服务提供经济支持,还显著降低了社会经济地位较高者的志愿服务意愿和水平。
上述发现证实了挤出效应假说,表明在社会保障体系欠发达且分层的发展中国家,国家主导的公共养老金可能会挤出老年人参与利他和互助性质的志愿活动。
