This is the second special issue of the International Journal of Comparative Sociology on the role of education systems as institutional settings on the reproduction of inequalities. The first was published in January 2021 and included papers that explored the role of shadow education and country characteristics during early childhood on educational inequalities. This special issue includes three papers that focus on stratification of the education system as a key driver of educational inequalities, cumulative (dis)advantage in the access to higher education, and student experiences in national educational systems. While we already elaborated on the research program, conceptual framework, and methodological challenges in the first introduction, we will deal with the current state-of-research in this second introduction.

教育系统和不平等的制度特征：引言二

这是《国际比较社会学杂志》的第二期特刊，主题是教育系统作为制度环境对不平等再生产的作用。第一篇发表于 2021 年 1 月，其中包括探讨影子教育和国家特征在幼儿期对教育不平等的作用的论文。本期特刊包括三篇论文，重点关注教育系统的分层作为教育不平等的关键驱动因素、获得高等教育的累积（不利）优势以及学生在国家教育系统中的经历。虽然我们已经在第一个介绍中详细阐述了研究计划、概念框架和方法论挑战，但我们将在第二个介绍中处理当前的研究状态。
