皮凯蒂（Piketty）关于教育与资本回报的核心结论是什么？它对不平等有何启示？
What is Piketty's core conclusion about education and returns to capital, and what does it imply for inequality?
皮凯蒂在《21世纪资本论》中指出，当资本收益率（r）长期高于经济增长率（g），财富向存量资本集中，劳动与教育的回报相对被削弱。他主张全球累进资本税以遏制世袭式不平等。
In Capital in the Twenty-First Century, Piketty argues that when the return on capital persistently exceeds growth, wealth concentrates in existing capital, weakening the relative rewards of labor and education. He proposes a global progressive capital tax to curb patrimonial inequality.

学校中的「能力分组」（tracking）为何可能产生「标签效应」而拉大成绩差距？
Why can school ability tracking produce a labeling effect that widens achievement gaps?
当学生被分流到不同层级班级，教师期望、同伴群体与课程深度随之分化，自我实现预言使被标为「低能」者降低投入。实证研究（如 Oakes）显示，分流常以阶层与种族为隐性边界，固化而非弥合不平等。
Once students are streamed into levels, teacher expectations, peer groups, and curriculum depth diverge, and the self-fulfilling prophecy leads low-track students to disengage. Research such as Oakes shows tracking often follows class and race lines, cementing rather than closing inequality.

为何识别「教育回报率」的因果关系需要工具变量？常用工具是什么？
Why does identifying the causal return to education require instrumental variables, and what instruments are commonly used?
受教育年限与能力、家庭背景等混淆因素相关，简单回归会高估回报。研究者用「义务教育法变动」「学校距离」等外生工具隔离教育的因果效应，卡卡万（Card）以此估计美国教育的局部平均处理效应。
Years of schooling correlate with ability and family background, so naive regression overstates returns. Researchers use exogenous instruments like compulsory-schooling-law changes or school distance to isolate causality; Card used such instruments to estimate local average treatment effects in the US.

什么是「直升机父母」现象？过度介入可能对子女自主性产生什么影响？
What is helicopter parenting, and how might over-involvement affect children's autonomy?
直升机父母指过度关注、随时介入子女生活的教养方式。研究提示，过度监控可能削弱孩子的独立解决问题能力与内在动机，并在升学后增加焦虑与依赖，但适度支持仍有益发展。
Helicopter parenting describes over-involved, constantly monitoring child-rearing. Studies suggest excessive control can weaken children's independent problem-solving and intrinsic motivation and raise anxiety and dependency at college, though moderate support remains beneficial.

什么是义务教育？它如何影响机会平等？
What is compulsory education, and how does it affect equality of opportunity?
义务教育由国家依法规定、免费且强制适龄儿童入学，通常为九年左右。它通过普及基础人力资本、削弱家庭背景对早期教育的决定作用，为后续社会流动提供共同起点。
Compulsory education is state-mandated, free, and required schooling for children, typically around nine years. By universalizing basic human capital and weakening family background's grip on early learning, it provides a common starting point for later mobility.

布迪厄的「文化资本」概念指什么？它如何在学校中转化为优势？
What does Bourdieu mean by cultural capital, and how is it converted into advantage at school?
文化资本指家庭传递的语言、品味、教养与知识等符号性资源。学校评价体系往往契合中产文化，使拥有这类资本的学生更易获得认可与高分数，从而把家庭背景转化为学业优势。
Cultural capital is the symbolic resources transmitted by families, such as language, taste, and knowledge. School evaluation tends to align with middle-class culture, so students possessing it gain recognition and grades, converting family background into academic advantage.

什么是代际流动性（intergenerational mobility）？社会学家通常如何测量它？
What is intergenerational mobility, and how do sociologists typically measure it?
代际流动性指子女的社会经济地位相对父母发生变动的程度。常用代际收入弹性（父母与子女收入排名的相关性）或地位获得模型（Blau-Duncan）来量化，数值越低代表流动性越高。
Intergenerational mobility is the extent to which children's socioeconomic status differs from their parents'. It is commonly measured by intergenerational income elasticity or status-attainment models; lower values mean more mobility.

社会学如何解释「寒门难出贵子」这一教育代际固化现象？
How does sociology explain the intergenerational educational persistence behind the idea that it is hard for the poor to rise?
该现象源于文化资本（家庭语言、教养方式）、经济资源与学校筛选机制叠加，使优势家庭能将其地位传递给子女。布迪厄指出，学校看似中立，实则复制了主导阶层的文化符码。
The pattern stems from the stacking of cultural capital, economic resources, and school selection, letting advantaged families transmit status. Bourdieu argued schools appear neutral yet reproduce the dominant class's cultural codes.
