The academic community has long held theoretical disagreements on this issue between static efficiency standards and dynamic equilibrium perspectives, and no integrated explanatory framework that combines economic logic, social context and temporal dimensions has yet been established. Drawing on new institutional economics, economic sociology, family life-cycle theory and intergenerational transmission theory, and proceeding through theoretical deduction, institutional context analysis and secondary evidence from policy documents, official statistics and literature, this paper develops a triple-constraint dynamic equilibrium framework for the moderate-scale operation of family farms in China; its purpose is explanatory rather than estimative, since no uniform optimal scale is defensible across heterogeneous regional endowments, crop systems, service conditions and family structures. The framework holds that moderate scale is not a fixed value set externally but a dynamic equilibrium interval of operating scale: the economic-efficiency constraint sets its lower bound, the social-embeddedness constraint sets its upper bound, and the intergenerational-sustainability constraint operates as an independent temporal condition that also moderates the position and width of the interval as the family life cycle and succession arrangements change. Seen thus, the factor-market, organisational-coordination and temporal-dimension failures observable in practice appear as three structural tensions that jointly compress the feasible interval and constrain the contribution of family farms to sustainable food-system goals. The contribution lies in bringing social embeddedness and intergenerational sustainability into the analysis of moderate scale, moving beyond a single-efficiency account and offering an integrated explanatory framework for the evolution of family-farm scale in transition economies with fragmented landholdings and household-centred production. The framework applies directly to family farms and other family-centred operations; its three constraints are analytically general, whereas their relative binding strength, the interval's position and the associated policy instruments remain conditional on the institutional environment, particularly China's collective land ownership and household contract responsibility system, so that its reference value for other transition economies is conditional rather than universal.","可持续食物系统的转型必须协调生产效率与供给韧性同小农生计保护之间的关系，而对于人口众多、耕地有限的经济体而言，这种协调在很大程度上取决于如何理解与组织家庭农场的经营规模。学术界长期以来在这一问题上存在理论分歧，表现为静态效率标准与动态均衡视角之间的对立，且尚未建立起一个将经济逻辑、社会情境与时间维度相结合的综合解释框架。本文借鉴新制度经济学、经济社会学、家庭生命周期理论与代际传承理论，通过理论推演、制度情境分析以及来自政策文件、官方统计与文献的二手证据，构建了中国家庭农场适度规模经营的三重约束动态均衡框架；其目的在于解释而非估算，因为在异质的区域禀赋、作物体系、服务条件与家庭结构之间，并不存在一个统一的最优规模。该框架认为，适度规模并非由外部设定的固定数值，而是经营规模的一个动态均衡区间：经济效率约束设定其下限，社会嵌入性约束设定其上限，而代际可持续性约束则作为独立的时间条件发挥作用，并随着家庭生命周期与继承安排的变化调节该区间的位置与宽度。由此观之，实践中可观察到的要素市场、组织协调与时间维度失灵，表现为三种结构性张力，它们共同压缩了可行区间，并制约了家庭农场对可持续食物系统目标的贡献。本文的贡献在于将社会嵌入性与代际可持续性纳入适度规模分析，超越单一效率解释，并为土地细碎化、以家庭为中心生产的转型经济体提供家庭农场规模演变的综合解释框架。该框架直接适用于家庭农场及其他以家庭为中心的经营活动；其三重约束在分析上具有一般性，而它们的相对约束强度、区间的位置以","2026-10-05T00:00:00Z",73,{"impact":40,"substance":75,"depth":76,"authority":19,"freshness":12,"relevant":21,"comment":77},20,18,"理论性论文，提出三重约束动态均衡框架，对家庭农场适度规模经营有解释力，但偏学术、政策落地性有限。",[79],{"name":9,"url":69},[26,81,82,27,28],"可持续食物系统","土地制度",{"code":39,"slug":84,"name":85,"path":86,"parent_code":87},"farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",[],{"status":90,"locked":13,"version":34,"method":35,"evidence":91},"classified",{"candidates":92,"agricultural_evidence":41},[93,99],{"code":39,"score":94,"supported":41,"title":95,"abstract":96,"tags":98},7,[],[26,97],"smallholder",[26],{"code":100,"score":21,"supported":13,"title":101,"abstract":102,"tags":103},"E2",[],[],[81],[105,106],"家庭农场

rural economic development, food security, employment generation, and sustainable use of natural resources. Although family farms differ considerably in size, specialization, ownership structure, and level of commercialization, they remain a dominant organizational form of agricultural production in many countries. This article examines international approaches to the development of family entrepreneurship in agriculture and identifies policy instruments that have contributed to the economic sustainability of family farms. The study applies comparative analysis, institutional analysis, generalization, and synthesis of international policy practices. Particular attention is given to the experiences of the European Union, the United States, Japan, South Korea, and Brazil. The analysis demonstrates that effective support systems for family farmers generally combine preferential financing, income support, investment assistance, access to technology, agricultural extension services, producer cooperation, market integration, and measures aimed at attracting young people to agriculture. The European Union experience demonstrates the importance of combining direct income support with environmental requirements and targeted assistance for small and young farmers. The United States provides an example of credit-guarantee and targeted lending mechanisms for family and beginning farmers. Japan emphasizes direct payments, environmental sustainability, and preservation of rural communities, while South Korea increasingly integrates family farming with smart agriculture, digital technologies, and innovation. Brazil's experience demonstrates the importance of dedicated financial and institutional mechanisms for family farming. The study concludes that there is no universal model of family entrepreneurship support; however, international experience indicates that a multidimensional policy framework combining finance, knowledge, technology, cooperation, and market access is more sustainable than isolated financial assistance.","农业中的家庭创业是农村经济发展、粮食安全、就业创造和自然资源可持续利用的重要组成部分。尽管家庭农场在规模、专业化程度、所有权结构和商业化水平方面存在显著差异，但在许多国家，它们仍然是农业生产的主导组织形式。本文考察了国际上促进农业家庭创业发展的做法，并识别了有助于家庭农场经济可持续性的政策工具。研究采用比较分析、制度分析、归纳总结以及国际政策实践综合等方法。研究特别关注欧盟、美国、日本、韩国和巴西的经验。分析表明，有效的家庭农民支持体系通常将优惠融资、收入支持、投资援助、技术获取、农业推广服务、生产者合作、市场融入以及旨在吸引年轻人从事农业的措施结合起来。欧盟的经验表明，将直接收入支持与环境要求以及对小农和年轻农民的有针对性援助相结合十分重要。美国提供了面向家庭农场和起步农民的信贷担保及定向贷款机制范例。日本强调直接支付、环境可持续性和农村社区保护，而韩国则日益将家庭农业与智慧农业、数字技术和创新相结合。巴西的经验表明，专门针对家庭农业的金融和制度机制十分重要。研究得出结论，不存在普遍适用的家庭创业支持模式；然而，国际经验表明，将金融、知识、技术、合作和市场准入相结合的多维政策框架，比孤立的财政援助更具可持续性。","Zenodo

sustainable food systems, rural livelihoods, and food security in Brazil, but many family farms in the Northeast still face labor constraints and limited access to machinery suited to small, fragmented, and diversified production systems. Scale-appropriate mechanization may offer a targeted pathway to address labor bottlenecks, improve operational timeliness, lower operational costs, and support locally adapted mechanization services. This study examined farm-level changes associated with the adoption of small- to medium-scale agricultural machinery in family-farming systems of Northeast Brazil, focusing on labor use, machine-use intensity, mechanization-related operational cost, and the practical conditions shaping mechanization outcomes. The analysis combined a purposively selected balanced before-and-after panel of 59 regular pilot-project machinery-using family farm cases, giving 118 observations. The before period represented farmers’ regular production practices, while the after period represented regular use of machinery introduced through the pilot project, complemented by operation-level field and qualitative evidence from Apodi, Russas MST, and Maranhão. Farmer fixed-effects models were used to estimate within-farmer before-and-after changes associated with machinery adoption. The results showed that labor use declined from 14.42 to 3.21 h\u002Fha, a reduction of 11.21 h\u002Fha or 77.72%, while machine use increased from 1.06 to 2.95 h\u002Fha, an increase of 1.89 h\u002Fha or 178.35%. Total mechanization-related operational cost declined from R$574.44 to R$184.77\u002Fha, a reduction of R$389.67\u002Fha or 67.83%. Operation-level evidence showed that the largest observed changes were concentrated in rice land preparation, vegetable bed preparation, inter-row weeding, forage harvesting, sowing, and rice harvesting. In Apodi, targeted mechanized operations reduced time by 50.0–96.3% and cost by 45.3–86.0%. In Russas, cooperative machinery use reduced selected operation costs by 61.7–88.5% while in Maranhão, mini combine harvesters sharply reduced rice harvesting time. These findings suggest that scale-appropriate mechanization can improve labor allocation and cost efficiency among machinery-using family-farm cases. However, the before-and-after design does not establish a full causal treatment effect, and sustained benefits depend on machine-agronomy fit, collective access, and localized mechanization support services.","家庭农业是巴西可持续粮食体系、农村生计和粮食安全的核心，但东北部许多家庭农场仍面临劳动力约束，以及适合小规模、细碎化和多样化生产体系的机械获取受限的问题。规模适配的机械化可能提供一条有针对性的路径，以缓解劳动力瓶颈、改善作业及时性、降低作业成本，并支持适应当地的机械化服务。本研究考察了巴西东北部家庭农业体系中采用中小型农业机械相关的农场层面变化，重点关注劳动力使用、机械使用强度、机械化相关作业成本，以及塑造机械化结果的实际条件。分析结合了一个有目的选取的平衡前后面板，包含59个常规试点项目机械使用家庭农场案例，共118个观测值。前期代表农民常规生产方式，后期代表通过试点项目引入的机械的常规使用，并辅以来自阿波迪、鲁萨斯MST和马拉尼昂的作业层面田间证据和定性证据。研究采用农民固定效应模型估计机械采用相关的农民内部前后变化。结果表明，劳动力使用从14.42小时\u002F公顷降至3.21小时\u002F公顷，减少11.21小时\u002F公顷，降幅77.72%；机械使用从1.06小时\u002F公顷增至2.95小时\u002F公顷，增加1.89小时\u002F公顷，增幅178.35%。机械化相关总作业成本从574.44雷亚尔\u002F公顷降至184.77雷亚尔\u002F公顷，减少389.67雷亚尔\u002F公顷，降幅67.83%。作业层面证据表明，观测到的最大变化集中在水稻整地、蔬菜苗床准备、行间除草、饲草收获、播种和水稻收获。在阿波迪，有针对性的机械化作业使时间减少50.0%–96.3%，成本降低45.3%–86.0%。在鲁萨斯，合作社机械使用使部分选定作业成本降低61.7%–88.5%；而在马拉尼昂，小型联合收割机大幅缩短了水稻收获时间。这些发现表明，规模适配的机械化可以改善机械使用家庭农场案例中的劳动力配置和成本效率。然而，前后设计并不能确立完整的因果处理效应，持续收益取决于机械—农艺适配性、集体获取途径和本地化机械化支持服务。","2026-09-22T00:00:00Z",{"impact":40,"substance":17,"depth":18,"authority":19,"freshness":12,"relevant":21,"comment":326},"基于巴西东北部59个家庭农场前后对比面板的实证研究，量化了适度规模机械化的节本增效效果，方法清晰、数据具体，对国内丘陵山区农机化与小农户服务体系建设有借鉴价值，但属境外案例、影响层级有限。",[328],{"name":9,"url":321},[26,330,331,332,333],"农业机械化","小农户","农机社会化服务","巴西农业",{"code":335,"slug":336,"name":337,"path":338,"parent_code":339},"F5","machinery","农机装备与机械化","\u002Ftopic\u002Finputs-equipment\u002Fmachinery","F",[],{"status":90,"locked":13,"version":34,"method":35,"evidence":342},{"candidates":343,"agricultural_evidence":41},[344,352,359,363,370,377,381],{"code":335,"score":12,"supported":41,"title":345,"abstract":346,"tags":351},[],[347,348,349,350],"农业机械","机械化","收割机","agricultural machinery",[330],{"code":353,"score":64,"supported":41,"title":354,"abstract":355,"tags":358},"A1",[],[356,357],"水稻","rice",[],{"code":232,"score":64,"supported":41,"title":360,"abstract":361,"tags":362},[],[235,236],[],{"code":364,"score":64,"supported":41,"title":365,"abstract":366,"tags":369},"B1",[],[367,368],"蔬菜","vegetable",[],{"code":371,"score":64,"supported":41,"title":372,"abstract":373,"tags":376},"C4",[],[374,375],"饲草","forage",[],{"code":39,"score":64,"supported":41,"title":378,"abstract":379,"tags":380},[],[26],[332,26,331],{"code":382,"score":50,"supported":41,"title":383,"abstract":384,"tags":386},"F4",[],[385],"除草",[],[388,389],"巴西 东北部 家庭农业 机械化","小规模农机 劳动力 成本","巴西东北部家庭农业机械化-3141",2,"10.3389\u002Ffsufs.2026.1897458",{"doi":392,"openalex_id":394,"authors":395,"venue":9,"cited_by_count":54,"oa_url":321,"card":410,"direction":59,"ingested_from":135},"W7213982637",[396,399,401,403,406,408],{"name":397,"orcid":398},"Abreham Arebe Tola","https:\u002F\u002Forcid.org\u002F0009-0002-8884-0196",{"name":400,"orcid":8},"Muhammad Mateen",{"name":402,"orcid":8},"Eribaldo Gomes Nobre Júnior",{"name":404,"orcid":405},"Vinícius Claudino de Sá","https:\u002F\u002Forcid.org\u002F0000-0002-9456-8937",{"name":407,"orcid":8},"Xindong Ni",{"name":409,"orcid":8},"Minli Yang",{"tldr":411,"method":412,"finding":413,"direction":59,"opportunity":414},"基于巴西东北部家庭农场面板数据，评估适度规模机械化对劳动、成本和机械使用的影响。","59个家庭农场前后平衡面板（118观测），农民固定效应模型，结合田间定性证据。","劳动投入降77.72%，机械使用增178.35%，机械化运营成本降67.83%。","可延伸研究：机械化与数字农艺服务结合，如何提升小农户机械-农艺匹配与持续收益。","2026-09-22T23:30:07.829960Z",{"id":417,"title":418,"url":419,"summary":420,"summary_zh":421,"content":8,"source_name":422,"source_url":419,"published_at":423,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":424,"score_detail":425,"sources":428,"tags":430,"primary_topic":434,"secondary_topics":440,"classification":441,"search_phrases":473,"slug":476,"view_count":21,"doi":477,"paper":478,"created_at":493},2779,"INFORMATION AND COMMUNICATION TECHNOLOGIES IN THE MANAGEMENT OF RISKS IN FAMILY AGRICULTURE: A SYSTEMATIC REVIEW OF THE LITERATURE","https:\u002F\u002Fdoi.org\u002F10.23900\u002Fartefactum.v25i9.4236","Family farming is relevant to food production, income generation and sustainable development, but it remains exposed to climatic, production, economic and operational risks.
