本页整理公开书目信息，不生成学术质量评分。AI 解读根据题名及所注明的摘要或原文片段生成，未完成全文核验，可能有误；具体假设、证明与结论请核对原文。摘要保留来源文本，未经模型改写。
DOI 首次登记不等于接收或发表日期。部分更正、评论等条目没有独立摘要；缺少可靠材料时保留待补状态。
引用量采用 OpenAlex 单条关联记录，不合计多个记录；关联记录可能包含正式发表版本，不等于此版本单独引用。缺失不视为零，引用指标不代表论文质量。
关注作者按书目中的完整姓名匹配，同名和姓名变体需人工辨别。相关论文先按共享细分方向和具体方法排列，再参考通用方法与发表日期。
分类依据与纠错
AI 根据所提供的论文材料归类：摘要明确说明住房券通过抽签随机分配，并比较处理与控制家庭结果，直接支持因果推断分类，未明确建模网络干扰。

邻里效应的实验分析
- 研究问题
- 通过抽签向高贫困公共住房家庭提供住房券后，家庭居住环境及成人和青少年的经济、健康与教育结果如何变化？
- 方法与思路
- 作者分析五个美国城市住房券随机分配后四至七年的结果，并利用券类型和城市间的处理强度差异考察贫困率关系。
- 材料陈述的贡献
- 摘要报告成人总体经济自立和身体健康无显著效应，心理健康及青少年结果存在性别差异，部分结果呈近似线性关系。
- 阅读关注点
- 阅读全文时应核对住房券提供与实际搬迁的估计对象、失访、多重检验，以及贫困率剂量关系所需的额外识别条件。
- 阅读边界
- 仅据所给 OpenAlex 摘要；效应大小和识别细节未说明，不显著不等于无效应，住房券随机化也不自动识别贫困率本身的效应。
原文摘要
Families, primarily female-headed minority households with children, living in high-poverty public housing projects in five U.S. cities were offered housing vouchers by lottery in the Moving to Opportunity program. Four to seven years after random assignment, families offered vouchers lived in safer neighborhoods that had lower poverty rates than those of the control group not offered vouchers. We find no significant overall effects of this intervention on adult economic self-sufficiency or physical health. Mental health benefits of the voucher offers for adults and for female youth were substantial. Beneficial effects for female youth on education, risky behavior, and physical health were offset by adverse effects for male youth. For outcomes that exhibit significant treatment effects, we find, using variation in treatment intensity across voucher types and cities, that the relationship between neighborhood poverty rate and outcomes is approximately linear.
