This study adopts a farm management perspective, using smallholder farmers as the main micro-level analytical unit, to explore viable paths for achieving sustainable agricultural structural transformation in China. The core contradiction facing China’s agricultural development—the ‘Smallholder Dilemma’—is conceptualised as four interrelated structural constraints: insufficient cropland per household unit, fragmentation of land holdings leading to a significant increase in production costs, acceleration of land de-agriculture, and systematic failure of land mobility policies. International comparative analyses suggest that major advances in agricultural modernisation have often occurred alongside improvements in land governance, market institutions, agricultural service systems, and the organisation of production; however, the country cases do not establish a universal causal sequence or a directly transferable quantitative benchmark. Based on these findings, this study proposes a three-stage institutional framework tailored to China’s context. The framework emphasises improving land transfer and service-market mechanisms in the short term, establishing a rights-protective and voluntary push–pull mechanism to support agricultural transition in the medium term, and promoting diversified agricultural production entities and organisational innovation in the long term.","中国持续存在的小农经营结构对农业现代化构成重大挑战。本研究从农场管理视角出发，以小农作为主要微观分析单元，探讨中国实现可持续农业结构转型的可行路径。中国农业发展面临的核心矛盾——“小农困境”——被概念化为四个相互关联的结构性约束：户均耕地不足、土地细碎化导致生产成本显著上升、土地去农业化加速，以及土地流转政策的系统性失灵。国际比较分析表明，农业现代化的重大进展往往伴随着土地治理、市场制度、农业服务体系和生产组织的改善；然而，国别案例并不能确立普遍的因果顺序或可直接移植的量化基准。基于上述发现，本研究提出了一个针对中国情境的三阶段制度框架。该框架强调：短期内完善土地流转和服务市场机制；中期建立权利保障型和自愿性的推拉机制以支持农业转型；长期促进多元化农业生产主体和组织创新。",null,"Cogent

barriers affect their management performance remains unclear, as prior studies focus mainly on classifying barriers. Methods Using survey data from 1,130 cooperatives in Shaanxi Province, China, this study applies ordinal logistic regression to examine the heterogeneous effects of perceived development barriers on management performance, with stepwise regression and Sobel tests identifying the mediating role of three management practices (strategic planning, resource investment, operational management). Two-period-lagged operating endowments are controlled to address reverse causality. Results The overall effect of barriers is insignificant, but dimensions differ markedly: resource and institutional barriers significantly reduce performance, whereas product-market and human-resource barriers show no overall effect. Management practices act as a channel—resource and institutional barriers exert a negative full mediating effect, product-market barriers a positive suppression effect, and human-resource barriers no effective pathway. Discussion Resource and institutional barriers are hierarchical: members’ insufficient willingness to contribute capital is the primary performance constraint, followed by land-transfer difficulties, while other policy constraints are common baseline conditions rather than core explanatory factors. Endogeneity and robustness tests support these findings.","引言 农民合作社是连接小农户与现代农业的关键，但不同发展障碍如何影响其经营绩效仍不明确，既有研究主要集中于对障碍进行分类。方法 本研究利用中国陕西省1130家合作社的调查数据，采用有序逻辑回归考察感知发展障碍对经营绩效的异质性影响，并通过逐步回归和Sobel检验识别三种管理实践（战略规划、资源投入、运营管理）的中介作用。为处理反向因果问题，研究控制了两期滞后的经营禀赋。结果 障碍的总体效应不显著，但各维度差异明显：资源障碍和制度障碍显著降低绩效，而产品市场障碍和人力资源障碍未表现出总体效应。管理实践发挥渠道作用——资源障碍和制度障碍产生负向完全中介效应，产品市场障碍产生正向抑制效应，人力资源障碍则无有效路径。讨论 资源障碍和制度障碍具有层级性：成员出资意愿不足是首要绩效约束，其次是土地流转困难，而其他政策约束属于常见基线条件而非核心解释因素。内生性和稳健性检验支持上述发现。","Frontiers in Sustainable Food Systems","2026-09-16T00:00:00Z",75,{"impact":152,"substance":18,"depth":19,"authority":20,"freshness":100,"relevant":22,"comment":153},15,"基于陕西1130家合作社微观调查，揭示资源与制度壁垒对经营绩效的异质性影响及管理实践中介机制，样本规模与方法设计扎实，对合作社扶持政策有参考价值。",[155],{"name":148,"url":145},[157,29,30,158,159],"乡村振兴","农民合作社","农业经营主体",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":163},{"candidates":164,"agricultural_evidence":47},[165,169],{"code":33,"score":118,"supported":47,"title":166,"abstract":167,"tags":168},[],[30,158,27],[29,159,158,30],{"code":37,"score":22,"supported":14,"title":170,"abstract":171,"tags":172},[],[],[157],[174,175],"农业社会化服务 农业经营主体 农民合作社 乡村振兴","农业社会化服务 农业经营主体","农业社会化服务农业经营主体农民合作社乡村振兴-2758","10.3389\u002Ffsufs.2026.1934606",{"doi":177,"openalex_id":179,"authors":180,"venue":148,"cited_by_count":78,"oa_url":190,"card":191,"direction":84,"ingested_from":86},"W7213418458",[181,184,186,188],{"name":182,"orcid":183},"Shihan Chen","https:\u002F\u002Forcid.org\u002F0000-0001-9790-3174",{"name":185,"orcid":9},"Sihan Jiang",{"name":187,"orcid":9},"Haiyan Wang",{"name":189,"orcid":9},"Jikun Ma","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1934606\u002Fpdf",{"tldr":192,"method":193,"finding":194,"direction":84,"opportunity":195},"基于陕西1130家合作社调查，分析感知发展障碍对管理绩效的异质性影响及传导机制。","有序Logistic回归、逐步回归与Sobel检验，控制两期滞后经营禀赋。","资源与制度障碍显著降低绩效，管理实践起中介作用，成员出资意愿不足是首要约束。","可探究数字技术能否缓解资源与制度障碍，并优化合作社管理实践的中介路径。","2026-09-17T23:30:08.060675Z",{"id":198,"title":199,"url":200,"summary":201,"summary_zh":202,"content":9,"source_name":148,"source_url":200,"published_at":203,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":204,"score_detail":205,"sources":207,"tags":209,"primary_topic":212,"secondary_topics":213,"classification":214,"search_phrases":236,"slug":239,"view_count":61,"doi":240,"paper":241,"created_at":255},1976,"Agro-dealer advisory services and the promotion of commercial organic fertilizers among smallholder farmers in Kenya","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1868413","Background Declining soil fertility, particularly rising acidity from prolonged use of synthetic fertilizers, remains a major constraint on crop productivity in Sub-Saharan Africa. Commercial organic fertilizers (COFs) provide a sustainable alternative by enriching soils with essential nutrients and enhancing structure and microbial activity. Agro-dealers, as central intermediaries in input supply chains, are strategically placed to promote COFs, yet their advisory role is not well understood. Methods This study examines factors influencing agro-dealers' provision of COF advisory services in Kenya, using data from 584 agro-input retailers across six counties. Conditional Mixed Process (CMP) models and Maximum Likelihood Seemingly Unrelated Regression are applied to estimate the effects of soil, agronomic, and fertilizer-specific factors on advisory behavior. Results Results show that knowledge, supplier incentives, and involvement in demonstration plots strongly predict advisory services, while soil degradation, crop stage, and weather also matter. Conclusion Findings underscore the importance of training, extension support, and market incentives in strengthening advisory capacity.","背景 土壤肥力下降，尤其是长期使用合成肥料导致的土壤酸化加剧，仍是撒哈拉以南非洲作物生产力的主要制约因素。商业有机肥料通过向土壤补充必需养分、改善土壤结构并增强微生物活性，提供了一种可持续的替代方案。农资经销商作为投入品供应链中的核心中介，处于推广商业有机肥料的战略位置，但其咨询服务职能尚未得到充分认识。方法 本研究利用肯尼亚六个县的584家农资零售商数据，考察影响农资经销商提供商业有机肥料咨询服务的关键因素。采用条件混合过程模型和极大似然似不相关回归，估计土壤、农艺及肥料特定因素对咨询服务行为的影响。结果 结果显示，知识水平、供应商激励措施及参与示范田活动对咨询服务具有显著预测作用，同时土壤退化状况、作物生育阶段及天气条件亦产生影响。结论 研究结果强调，培训、推广支持及市场激励在增强咨询服务能力方面具有重要意义。","2026-09-08T00:00:00Z",64,{"impact":118,"substance":46,"depth":17,"authority":118,"freshness":70,"relevant":22,"comment":206},"研究农资经销商推广有机肥的咨询服务影响因素，对农业技术推广有参考价值，但地域和时效性有限。",[208],{"name":148,"url":200},[210,27,29,211],"肯尼亚","有机肥",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":215},{"candidates":216,"agricultural_evidence":47},[217,221,229],{"code":33,"score":13,"supported":47,"title":218,"abstract":219,"tags":220},[49],[],[29,27],{"code":222,"score":223,"supported":47,"title":224,"abstract":225,"tags":228},"F3",7,[],[226,227],"肥料","fertilizer",[211],{"code":230,"score":89,"supported":47,"title":231,"abstract":232,"tags":235},"H2",[],[233,234],"土壤","soil",[],[237,238],"农业社会化服务 小农户 有机肥 肯尼亚","农业社会化服务 小农户","农业社会化服务小农户有机肥肯尼亚-1976","10.3389\u002Ffsufs.2026.1868413",{"doi":240,"openalex_id":242,"authors":243,"venue":148,"cited_by_count":78,"oa_url":200,"card":250,"direction":84,"ingested_from":86},"W7211940467",[244,246,248],{"name":245,"orcid":9},"Castro N.

A classifier is modelled as a concept-rank operator whose singular values govern how much concept-level signal survives the projection from pixel space to class logits, and a collapse audit is defined as the ratio of retained concept-rank energy to total concept energy. Under a low-label regime, where concept annotations are scarce and the audit must be estimated from few labelled examples, the bound predicts that audit reliability degrades as a function of the concept-rank spectrum and the label budget. The analysis is a theoretical and methodological contribution: it derives the bound, states the conditions under which a collapse audit is identifiable, and characterises the operating characteristics of the audit as a decision procedure under a declared variance structure (between-cluster SD = 6.0, residual SD = 4.5, intraclass correlation = 0.64). Power was estimated across 2000 design cells for cluster counts of 8, 16, 24 and 32 and effect sizes of 3, 5 and 8 percentage points; 52 clusters were required for 5 percentage points at 80% power.

It defines a temporal-stability audit as a sequence of concept-probe accuracies measured across defined phenological windows, and it derives an interpretability decay bound: the rate at which probe accuracy can fall before the fungicide-timing decision it is meant to support becomes unreliable. The bound is expressed as a function of the probe's initial margin, the drift in concept prevalence between windows, and the classifier's sensitivity to the drifted features, and it yields a certified audit interval rather than a single-point certificate.

Power was estimated across 2000 design cells over cluster counts of 8, 16, 24 and 32 and effect sizes of 3, 5 and 8 percentage points; 54 clusters were required for 5 percentage points at 80% power. The contribution is a decision-theoretic account of when a concept-probe certificate expires, and a design rule for scheduling re-audits across the season.","概念探针审计（concept-probe audit）日益被用于验证作物病害分类器的内部表征是否追踪小农户会据以采取行动的病理学概念，但在生长季某一时点获得认证的探针，可能随着物候变化改变田间的视觉统计特征而悄然与这些概念脱钩。本分析将这种脱钩视为一个形式化对象。它将时间稳定性审计（temporal-stability audit）定义为在既定物候窗口内测量的一系列概念探针准确率，并推导出一个可解释性衰减界限（interpretability decay bound）：即探针准确率在其所支持的杀菌剂施用时机决策变得不可靠之前所能下降的速率。该界限表示为探针初始裕度、窗口间概念流行率漂移以及分类器对漂移特征敏感度的函数，并给出一个经认证的审计区间而非单点认证。随后，本文在声明的方差结构下刻画该审计设计的运行特征，采用基于重复的前后对照影响估计量评估，其中组间标准差 = 6.0、残差标准差 = 4.5、组内相关系数 = 0.64。功效在 2000 个设计单元上估计，聚类数取 8、16、24 和 32，效应量取 3、5 和 8 个百分点；在 80% 功效下达到 5 个百分点需要 54 个聚类。本文的贡献在于从决策论角度阐明概念探针认证何时失效，并给出在整个生长季内安排重新审计的设计规则。",70,{"impact":21,"substance":328,"depth":17,"authority":118,"freshness":13,"relevant":22,"comment":329},22,"该论文提出概念探针审计的时序稳定性框架与可解释性衰减界，方法新颖、统计设计扎实，但属小众方法论研究，产业影响有限，适合作为专业精选而非头条。",[331],{"name":262,"url":323},[270,271,27,333,334],"作物病害识别","模型审计",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[337],{"code":277,"slug":278,"name":279,"path":280,"parent_code":281},{"status":40,"locked":14,"version":41,"method":42,"evidence":339},{"candidates":340,"agricultural_evidence":47},[341,345,349],{"code":33,"score":152,"supported":47,"title":342,"abstract":343,"tags":344},[49],[27,49],[27],{"code":277,"score":13,"supported":47,"title":346,"abstract":347,"tags":348},[291],[],[333,271],{"code":295,"score":22,"supported":14,"title":350,"abstract":351,"tags":352},[],[],[270],[354,355],"概念探针 时序稳定性 作物病害分类器","杀菌剂 施药时机 可解释性衰减","概念探针时序稳定性作物病害分类器-5590","10.5281\u002Fzenodo.23545234",{"doi":357,"openalex_id":359,"authors":360,"venue":262,"cited_by_count":78,"oa_url":323,"card":367,"direction":317,"ingested_from":86},"W7223088030",[361,363,365],{"name":362,"orcid":9},"Abdi-Basid Idriss Farah",{"name":364,"orcid":9},"Amina Abdillahi Guedi",{"name":366,"orcid":9},"Moussa Omar Youssouf",{"tldr":368,"method":369,"finding":370,"direction":317,"opportunity":371},"提出概念探针时间稳定性审计与可解释性衰减界，判断何时需重新审计。","定义跨物候窗口探针精度序列，推导衰减界，用BACI复制评估统计功效。","5个百分点效应需54个聚类达80%功效，审计证书会随物候漂移过期。","可将衰减界与再审计调度规则嵌入小农户杀菌剂时机决策支持系统，并验证跨作物泛化。","2026-10-22T11:21:08.978348Z",{"id":374,"title":375,"url":376,"summary":377,"summary_zh":378,"content":9,"source_name":148,"source_url":376,"published_at":263,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":379,"score_detail":380,"sources":382,"tags":384,"primary_topic":389,"secondary_topics":390,"classification":391,"search_phrases":428,"slug":431,"view_count":78,"doi":432,"paper":433,"created_at":462},5548,"Agroecological transition in olive based farming systems among smallholder farms in northwestern Tunisia","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1903591","Agricultural intensification has increased production and economic growth but has also generated significant environmental and social challenges that threaten long-term sustainability, highlighting the need for more sustainable farming models. Agroecology offers a promising pathway to enhance resilience and support inclusive rural development. In this context, Tunisia’s olive sector provides a relevant case for examining agroecological transitions in semi-arid smallholder systems. This study evaluates the degree of agroecological transition among smallholder olive farms in the Elles region of northwestern Tunisia using the FAO Tool for Agroecology Performance Evaluation (TAPE). Based on a sample of 60 farms, the analysis applies the Characterization of Agroecological Transition (CAET) index, grounded in the 10 Elements of Agroecology, to compare four production systems: (i) olive monoculture, (ii) diversified cropping, (iii) olive–livestock integration, and (iv) integrated olive–crop–livestock systems. Economic, social, environmental and institutional performance were explored using the TAPE Core Criteria of Performance (Step 2) and examined in relation to CAET scores. Results reveal a clear agroecological gradient, with diversified and integrated systems achieving markedly higher CAET scores (up to 52%) compared to monoculture systems (31%). Spearman correlations show strong associations between CAET and key dimensions, including synergy (ρ = 0.79), human and social values (ρ = 0.78), and diversity (ρ = 0.71). Several TAPE economic performance indicators, including monthly income, which ranged from approximately 1,349 TND in monoculture systems to 4,892 TND in diversified olive–crop–livestock systems, were positively associated with higher CAET scores, suggesting that agroecological transition may not necessarily imply a trade-off between productivity and sustainability. However, limited collective action, weak market integration, and insufficient extension services constrain broader adoption. These findings highlight the potential of diversification as a key lever for agroecological transition and underscore the importance of targeted policy support.","农业集约化提高了产量并促进了经济增长，但也产生了威胁长期可持续性的重大环境与社会挑战，凸显了对更可持续耕作模式的需求。农业生态学为增强韧性和支持包容性农村发展提供了一条有前景的路径。在此背景下，突尼斯橄榄产业为研究半干旱小农系统中的农业生态转型提供了相关案例。本研究利用联合国粮农组织农业生态性能评价工具（TAPE），评估突尼斯西北部埃勒斯地区小农橄榄农场的农业生态转型程度。基于60个农场的样本，分析采用以农业生态学十大要素为基础的农业生态转型特征（CAET）指数，比较四种生产系统：（i）橄榄单作，（ii）多样化种植，（iii）橄榄—畜牧结合，以及（iv）橄榄—作物—畜牧综合系统。研究利用TAPE核心性能标准（第二步）探讨经济、社会、环境和制度绩效，并将其与CAET得分进行关联分析。结果揭示了明显的农业生态梯度，多样化与综合系统的CAET得分（最高达52%）显著高于单作系统（31%）。斯皮尔曼相关性分析显示，CAET与关键维度之间存在强关联，包括协同性（ρ = 0.79）、人文与社会价值（ρ = 0.78）和多样性（ρ = 0.71）。若干TAPE经济绩效指标——包括月收入，其从单作系统的约1，349突尼斯第纳尔到橄榄—作物—畜牧多样化系统的4，892突尼斯第纳尔不等——与更高的CAET得分呈正相关，表明农业生态转型未必意味着生产力与可持续性之间的权衡。然而，集体行动有限、市场整合薄弱和推广服务不足制约了更广泛的采纳。这些发现凸显了多样化作为农业生态转型关键杠杆的潜力，并强调了有针对性的政策支持的重要性。",71,{"impact":118,"substance":46,"depth":19,"authority":20,"freshness":100,"relevant":22,"comment":381},"基于FAO TAPE方法对突尼斯小农户橄榄系统农生态转型的实证研究，数据扎实、结论有新意，但属区域性案例，公共影响有限。",[383],{"name":148,"url":376},[27,385,386,387,388],"农业转型","生态农业","突尼斯","油橄榄",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":392},{"candidates":393,"agricultural_evidence":47},[394,398,405,411,418,424],{"code":33,"score":118,"supported":47,"title":395,"abstract":396,"tags":397},[49],[49],[27],{"code":399,"score":89,"supported":47,"title":400,"abstract":401,"tags":404},"C",[],[402,403],"畜牧","livestock",[],{"code":37,"score":89,"supported":47,"title":406,"abstract":407,"tags":410},[],[408,409],"农村发展","rural development",[],{"code":412,"score":89,"supported":47,"title":413,"abstract":414,"tags":417},"H6",[],[415,416],"农业生态","agroecology",[],{"code":419,"score":61,"supported":47,"title":420,"abstract":421,"tags":423},"H7",[],[422],"干旱",[],{"code":60,"score":22,"supported":14,"title":425,"abstract":426,"tags":427},[],[],[386],[429,430],"突尼斯 油橄榄 小农户","TAPE 农生态 评估","突尼斯油橄榄小农户-5548","10.3389\u002Ffsufs.2026.1903591",{"doi":432,"openalex_id":434,"authors":435,"venue":148,"cited_by_count":78,"oa_url":376,"card":456,"direction":460,"ingested_from":86},"W7223108121",[436,438,440,443,446,448,451,454],{"name":437,"orcid":9},"Rihab Mejri",{"name":439,"orcid":9},"Meriem Oueslati Zlaoui",{"name":441,"orcid":442},"Inès Gharbi","https:\u002F\u002Forcid.org\u002F0000-0003-2558-2134",{"name":444,"orcid":445},"Asma Souissi","https:\u002F\u002Forcid.org\u002F0000-0002-8680-5875",{"name":447,"orcid":9},"Ghada Ferchichi",{"name":449,"orcid":450},"Rania Soula","https:\u002F\u002Forcid.org\u002F0000-0002-6086-9176",{"name":452,"orcid":453},"Boubaker Dhehibi","https:\u002F\u002Forcid.org\u002F0000-0003-3854-6669",{"name":455,"orcid":9},"Mohamed Zied Dhraief",{"tldr":457,"method":458,"finding":459,"direction":460,"opportunity":461},"用FAO TAPE工具评估突尼斯西北小农橄榄农场生态农业转型程度。","FAO TAPE框架与CAET指数，调查60个农场比较四类种植系统。","多样化与综合系统CAET得分达52%，单作仅31%，且收入更高。","农业绿色发展与碳","可将TAPE与CAET指标数字化，构建小农生态转型监测与决策支持系统。","2026-10-22T11:20:15.716064Z"]
