Abstract: Social stratification and mobility comprises an important field of social demography and population studies. Understanding social stratification and mobility hinges on knowledge of early lifecourse (ages 0-18) development—its patterns and causes.Unfortunately, demographic research in China has only made limited efforts to examine early life-course development from the perspective of social stratification and mobility as of yet, partly due to lacking a comprehensive conceptual framework for guidance. To address this issue, we propose a two-level and multi-factor theoretical framework based on the existing literature. Two-level refers to the macro level and the micro level. Multi-factor refers to the numerous influential factors affecting early-life development, which broadly fall into two categories: social and economic. This study contributes to population research by providing a comprehensive roadmap and guidance for future research on early-life development in China.

摘要： 社会分层与流动是社会人口学的重要研究主题,而理解社会分层与流动的关键在于认清生命历程早期阶段(0 ~ 18 岁)的发展差异及其影响因素。 但到目前为止,中国关于生命历程早期阶段尤其是在社会分层与流动的视角下考察早期发展的研究仍十分有限,其核心问题在于缺乏一个整体性的分析框架。 鉴于此,通过系统回顾和梳理国内外相关理论与经验研究,提出一个“双层次多因素”分析框架,并探讨该框架在中国儿童发展研究中的具体应用。 “双层次”指“宏观层次”与“微观层次”,“多因素”系“经济因素”与“社会因素”所囊括的诸多因素。 研究内容能够为中国今后有关生命历程早期发展的研究,尤其是从社会分层与流动的角度考察早期发展的人口研究提供方向、思路与议题。
