人口老龄化背景下代际经济支持反向流动现象研究

A Study on the Phenomenon of Reverse Intergenerational Economic Support Flow in the Context of Population Aging

摘要: 在人口老龄化进程不断加速的背景下，传统以“养儿防老”为核心的代际支持模式正发生显著转变，家庭内部逐渐出现代际经济支持反向流动现象，即部分成年子女在经济上持续依赖父母，形成“养老变养小”的现实格局。本文在梳理相关研究的基础上，结合生命周期理论、人力资本理论与福利制度替代理论，对该现象的表现形式、生成机制及其影响进行系统分析。研究发现，青年就业压力加大、住房成本上升及教育周期延长等宏观因素，与社会保障体系不完善及家庭主义文化观念共同作用，促使代际支持结构发生调整，并加重老年群体的经济负担与养老风险。进一步来看，这种反向流动不仅削弱了老年群体的生活保障水平，也在一定程度上延缓了青年独立进程，对家庭关系及社会结构产生深远影响。基于此，本文提出应从完善社会保障体系、优化青年发展环境及引导家庭责任边界等方面入手，以实现代际关系的合理调适与社会的可持续发展。

Abstract: Against the backdrop of accelerating population aging, the traditional intergenerational support model centered on “raising children for old-age care” is undergoing significant transformation. A reverse flow of intergenerational economic support is gradually emerging within families, where some adult children remain financially dependent on their parents—a phenomenon described as “reversing the traditional care model”. Building on existing research and integrating life cycle theory, human capital theory, and welfare system substitution theory, this paper systematically analyzes the manifestations, mechanisms, and impacts of this phenomenon. The study reveals that macro-level factors—including increased employment pressure on youth, rising housing costs, and extended education cycles—combined with an incomplete social security system and family-oriented cultural values, are driving adjustments in intergenerational support structures while exacerbating the economic burden and pension risks faced by the elderly. Furthermore, this reverse flow not only compromises the living security of older adults but also delays youth independence to some extent, profoundly affecting family dynamics and social structures. Accordingly, the paper proposes measures to enhance the social security system, optimize youth development environments, and clarify family responsibility boundaries, aiming to achieve rational intergenerational adaptation and sustainable societal development.
