Methods Using survey data from 302 households across four ethnic mountainous study sites in Chongqing, China, this study examines livelihood reorganization among return-migrant households through a rural–urban linkage lens. We constructed three composite indicators—basic livelihood conditions (BLC), food access-related livelihood capacity (FAC) and food stability-related livelihood capacity (FSC)—and examined these measures alongside income diversity and household food insecurity outcomes. Results Return-migrant households were concentrated in part-time, non-agriculture-dominant and non-agricultural livelihood types, while pure agricultural and agriculture-dominant types were less common. Their income diversity index, BLC, FAC and FSC were higher than those of non-return households, with values of 1.0434, 0.5758, 0.6006 and 0.6127, respectively, compared with 0.9196, 0.5404, 0.5568 and 0.5717. At the village level, Huaxi and Xinjian showed higher income diversification and livelihood capacity, whereas food insecurity risks were concentrated mainly in Dahekou and Dazhai. In the full sample, the incidence rates of worry about insufficient food and food shortage experience were 4.30% and 2.32%, respectively. Discussion These findings show that return migration does not automatically generate resilient livelihoods. Livelihood diversification was more closely aligned with food access and stability where income sources were stable, rural–urban linkages were maintained, livelihood conditions were stronger and village constraints were less severe.","引言 返乡迁移正在重塑民族山区乡村的生计方式，但关于其对生计能力和食物获取影响的农户层面证据仍然有限。方法 本研究利用中国重庆四个民族山区研究点302户家庭的调查数据，从城乡联系视角考察返乡迁移家庭的生计重组。我们构建了三个综合指标——基本生计条件（BLC）、食物获取相关生计能力（FAC）和食物稳定性相关生计能力（FSC），并将这些指标与收入多样性和家庭食物不安全结果一并考察。结果 返乡迁移家庭集中于兼业型、非农主导型和非农型生计类型，而纯农型和农业主导型较少。其收入多样性指数、BLC、FAC和FSC均高于非返乡家庭，分别为1.0434、0.5758、0.6006和0.6127，而非返乡家庭分别为0.9196、0.5404、0.5568和0.5717。在村庄层面，花溪和新建表现出更高的收入多样化和生计能力，而食物不安全风险主要集中在河口和大寨。在全样本中，担心食物不足和经历食物短缺的发生率分别为4.30%和2.32%。讨论 这些发现表明，返乡迁移并不会自动产生有韧性的生计。在收入来源稳定、城乡联系得以维持、生计条件较强且村庄约束较轻的情况下，生计多样化与食物获取和稳定性的契合更为紧密。",null,"Frontiers in Sustainable Food Systems","2026-09-17T00:00:00Z","论文",10,false,73,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":13,"relevant":21,"comment":22},12,21,17,13,1,"基于重庆民族山区302户调查的实证研究，揭示返乡回流与城乡联结对农户生计分化和食物获取的影响，数据扎实、结论有政策参考价值，但属细分领域学术成果，影响范围有限。",[24],{"name":10,"url":6},[26,27,28,29,30],"粮食安全","城乡融合","农户生计","返乡回流","山区乡村",0,"10.3389\u002Ffsufs.2026.1879585",{"doi":32,"openalex_id":34,"authors":35,"venue":10,"cited_by_count":31,"oa_url":6,"card":44,"direction":48,"ingested_from":50},"W7213464742",[36,38,40,42],{"name":37,"orcid":9},"Denghui Xu",{"name":39,"orcid":9},"Chunwang Sun",{"name":41,"orcid":9},"Zhewen Zheng",{"name":43,"orcid":9},"Xianhua Guo",{"tldr":45,"method":46,"finding":47,"direction":48,"opportunity":49},"基于重庆民族山区302户调查，分析返乡迁移对农户生计分化与食物获取的影响。","问卷调查与生计复合指标（BLC、FAC、FSC）及收入多样性分析。","返乡户生计多样性与食物获取能力更高，但生计韧性并非自动形成。","数字乡村与农业信息化","可结合数字技术追踪返乡户城乡联系与生计资本，构建食物安全预警模型。","openalex","2026-09-17T23:30:07.231529Z"]
