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。",null,"Frontiers in Sustainable Food Systems","2026-09-16T00:00:00Z","论文",10,false,75,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},15,21,17,13,9,1,"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。",[25],{"name":10,"url":6},[27,28,29,30,31],"乡村振兴","农业社会化服务","土地流转","农民合作社","农业经营主体",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"G2","farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",[],{"status":40,"locked":14,"version":41,"method":42,"evidence":43},"classified","2026-10-22.2","rules",{"candidates":44,"agricultural_evidence":47},[45,52],{"code":33,"score":46,"supported":47,"title":48,"abstract":49,"tags":51},12,true,[],[29,30,50],"小农户",[28,31,30,29],{"code":37,"score":22,"supported":14,"title":53,"abstract":54,"tags":55},[],[],[27],[57,58],"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",2,"10.3389\u002Ffsufs.2026.1934606",{"doi":61,"openalex_id":63,"authors":64,"venue":10,"cited_by_count":74,"oa_url":75,"card":76,"direction":80,"ingested_from":82},"W7213418458",[65,68,70,72],{"name":66,"orcid":67},"Shihan Chen","https:\u002F\u002Forcid.org\u002F0000-0001-9790-3174",{"name":69,"orcid":9},"Sihan Jiang",{"name":71,"orcid":9},"Haiyan Wang",{"name":73,"orcid":9},"Jikun Ma",0,"https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1934606\u002Fpdf",{"tldr":77,"method":78,"finding":79,"direction":80,"opportunity":81},"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。","数字乡村与农业信息化","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。","openalex","2026-09-17T23:30:08.060675Z",{"total":85,"page":22,"page_size":85,"items":86},6,[87,154,211,260,315,389],{"id":88,"title":89,"url":90,"summary":91,"summary_zh":92,"content":9,"source_name":10,"source_url":90,"published_at":93,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":94,"score_detail":95,"sources":100,"tags":102,"primary_topic":105,"secondary_topics":106,"classification":107,"search_phrases":132,"slug":135,"view_count":74,"doi":136,"paper":137,"created_at":153},5368,"The enabling effect of farmers’ cooperatives on the rural collective economy: evidence from China","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1971166","Based on panel data from 30 provinces in China covering the period 2015–2023, this paper examines the impact of farmers’ cooperatives on the rural collective economy and the underlying mechanisms. First, a multidimensional evaluation system is constructed to measure the development levels of farmers’ cooperatives and the rural collective economy. Subsequently, baseline regressions are estimated using a two-way fixed-effects model and the instrumental variables approach, while the underlying mechanisms are systematically identified through moderating-effect models, threshold-effect models, spatial econometric models, and dimension-specific tests. The results indicate that, during the study period, the overall development levels of China’s farmers’ cooperatives and the rural collective economy showed distinct temporal evolutionary characteristics. Specifically, the overall development level of farmers’ cooperatives declined slightly, while the rural collective economy maintained steady growth. Baseline regression results show that the development of farmers’ cooperatives has a significant positive promotional effect on the rural collective economy, and this conclusion remains robust after multiple robustness tests and endogeneity treatments. Mechanism analysis reveals that cooperatives primarily exert their empowering effect through two channels: improving operational performance and promoting industrial upgrading, whereas their effects in dimensions such as standardized operation and service scope are not significant. Heterogeneity tests confirm that this promotional effect exhibits marked regional differentiation, being significant only in the eastern regions and not yet manifested in the central and western regions. Further analysis indicates that the agricultural industry growth rate plays a positive moderating role in the process by which cooperatives empower the collective economy; the level of land transfer exhibits a single-threshold effect, with the cooperative’s promotional effect strengthening significantly once the threshold value is exceeded. Moreover, the development of farmers’ cooperatives exhibits significant positive spatial spillover effects, driving the development of the collective economy in neighboring regions through factor mobility and industrial linkages.","基于2015—2023年中国30个省份的面板数据，本文考察了农民合作社对农村集体经济的影响及其作用机制。首先，构建多维评价体系测度农民合作社与农村集体经济的发展水平。随后，采用双向固定效应模型和工具变量法进行基准回归估计，同时通过调节效应模型、门槛效应模型、空间计量模型及分维度检验系统识别其内在机制。结果表明，研究期内中国农民合作社与农村集体经济的整体发展水平呈现明显的时间演变特征。具体而言，农民合作社整体发展水平略有下降，而农村集体经济保持稳定增长。基准回归结果显示，农民合作社发展对农村集体经济具有显著的正向促进作用，且该结论在多重稳健性检验和内生性处理后依然成立。机制分析发现，合作社主要通过提升经营绩效和促进产业升级两条渠道发挥赋能作用，而在规范运营和服务范围等维度上的效应不显著。异质性检验证实，该促进作用呈现明显的区域分化特征，仅在东部地区显著，中西部地区尚未显现。进一步分析表明，农业产业增长率在合作社赋能集体经济的过程中发挥正向调节作用；土地流转水平呈现单一门槛效应，一旦跨越门槛值，合作社的促进作用显著增强。此外，农民合作社发展具有显著的正向空间溢出效应，通过要素流动和产业关联带动邻近地区集体经济发展。","2026-10-19T00:00:00Z",79,{"impact":96,"substance":97,"depth":96,"authority":20,"freshness":98,"relevant":22,"comment":99},18,22,8,"基于30省面板数据的实证研究，方法扎实、结论有新意，对合作社赋能集体经济具政策参考价值。",[101],{"name":10,"url":90},[27,103,104,29,30],"空间溢出","农村集体经济",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":108},{"candidates":109,"agricultural_evidence":47},[110,116,123,127],{"code":33,"score":111,"supported":47,"title":112,"abstract":113,"tags":115},11,[],[29,30,114],"land transfer",[30,29],{"code":117,"score":118,"supported":47,"title":119,"abstract":120,"tags":122},"I4",4,[],[121],"空间计量",[103],{"code":37,"score":22,"supported":14,"title":124,"abstract":125,"tags":126},[],[],[27],{"code":128,"score":22,"supported":14,"title":129,"abstract":130,"tags":131},"G4",[],[],[104],[133,134],"农民合作社 农村集体经济","合作社 土地流转 门槛效应","农民合作社农村集体经济-5368","10.3389\u002Ffsufs.2026.1971166",{"doi":136,"openalex_id":138,"authors":139,"venue":10,"cited_by_count":74,"oa_url":147,"card":148,"direction":80,"ingested_from":82},"W7222921695",[140,143,145],{"name":141,"orcid":142},"Miao Qian","https:\u002F\u002Forcid.org\u002F0009-0006-6758-2924",{"name":144,"orcid":9},"Xiuyu Huang",{"name":146,"orcid":9},"Jiaomeng Li","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1971166\u002Fpdf",{"tldr":149,"method":150,"finding":151,"direction":80,"opportunity":152},"基于2015–2023年30省面板数据，检验农民合作社对农村集体经济的促进效应及机制。","双向固定效应模型、工具变量法、调节\u002F门槛\u002F空间计量模型及多维评价体系。","合作社通过提升经营绩效与产业升级显著促进集体经济，效应仅东部显著且有正向空间溢出。","可探究中西部效应缺失原因，并引入数字化指标考察合作社信息化对集体经济的赋能路径。","2026-10-20T23:30:06.525852Z",{"id":155,"title":156,"url":157,"summary":158,"summary_zh":159,"content":9,"source_name":160,"source_url":157,"published_at":161,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":162,"score_detail":163,"sources":165,"tags":167,"primary_topic":170,"secondary_topics":171,"classification":172,"search_phrases":193,"slug":196,"view_count":60,"doi":197,"paper":198,"created_at":210},3678,"An exploration of sustainable scaled-up operations for smallholder farms in China: drawing on international experience","https:\u002F\u002Fdoi.org\u002F10.1080\u002F23311932.2026.2736893","China’s persistent smallholder farming structure presents a major challenge for agricultural modernisation. 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。","Cogent Food & Agriculture","2026-09-25T00:00:00Z",77,{"impact":96,"substance":18,"depth":19,"authority":20,"freshness":98,"relevant":22,"comment":164},"从农场管理视角系统剖析中国小农困境并提出三阶段制度框架，国际比较扎实，对农业现代化与土地政策研究有参考价值。",[166],{"name":160,"url":157},[50,168,28,29,169],"农业现代化","土地治理",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":173},{"candidates":174,"agricultural_evidence":47},[175,181,186],{"code":33,"score":176,"supported":47,"title":177,"abstract":179,"tags":180},20,[178],"smallholder",[29,178,114],[28,29,50],{"code":182,"score":118,"supported":47,"title":183,"abstract":184,"tags":185},"J2",[],[168],[168],{"code":187,"score":188,"supported":47,"title":189,"abstract":190,"tags":192},"H8",3,[],[191],"可持续农业",[],[194,195],"小农户 土地流转 农业现代化","小农困境 土地治理","小农户土地流转农业现代化-3678","10.1080\u002F23311932.2026.2736893",{"doi":197,"openalex_id":199,"authors":200,"venue":160,"cited_by_count":74,"oa_url":204,"card":205,"direction":80,"ingested_from":82},"W7214366575",[201],{"name":202,"orcid":203},"Yujia Huo","https:\u002F\u002Forcid.org\u002F0009-0005-2578-2859","https:\u002F\u002Fwww.tandfonline.com\u002Fdoi\u002Fpdf\u002F10.1080\u002F23311932.2026.2736893?needAccess=true",{"tldr":206,"method":207,"finding":208,"direction":80,"opportunity":209},"基于农场管理视角，分析中国小农困境并借鉴国际经验提出三阶段制度框架。","国际比较分析与制度经济学框架，以小农为微观分析单元。","小农困境源于四重结构约束，需分短期、中期、长期三阶段制度创新。","可探究数字平台与土地流转、服务市场机制结合如何缓解小农困境。","2026-09-28T23:30:42.560643Z",{"id":212,"title":213,"url":214,"summary":215,"summary_zh":9,"content":9,"source_name":216,"source_url":9,"published_at":217,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":218,"score_detail":219,"sources":221,"tags":223,"primary_topic":226,"secondary_topics":227,"classification":228,"search_phrases":246,"slug":249,"view_count":74,"doi":250,"paper":251,"created_at":259},5457,"数字化水平、农业社会化服务对农业现代化的影响 (Impact of Digitalization and Agricultural Socialized Services on Agricultural Modernization)","http:\u002F\u002Fzgnjhxb.niam.com.cn\u002FCN\u002F10.13733\u002Fj.jcam.issn.2095-5553.2026.10.031","基于2013—2023年30个省份面板数据，熵值TOPSIS法测度农业现代化指数，双向固定效应模型检验机制。数字化显著促进农业现代化，经市场化水平传导，农业社会化服务起调节作用。对非粮食主产区显著，对主产区不显著。","中国农机化学报 2026-10-20","2026-10-20T00:00:00Z",78,{"impact":96,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":220},"基于30省十年面板数据的实证研究，方法规范、结论有政策参考价值，但属学术论文而非产业事件，适合精选但非头条。",[222],{"name":216,"url":214},[224,225,168,28],"数字乡村","省级面板",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":229},{"candidates":230,"agricultural_evidence":47},[231,236,241],{"code":182,"score":176,"supported":47,"title":232,"abstract":234,"tags":235},[168,233],"agricultural modernization",[168],[168],{"code":33,"score":46,"supported":47,"title":237,"abstract":239,"tags":240},[238],"社会化服务",[238],[28],{"code":242,"score":22,"supported":14,"title":243,"abstract":244,"tags":245},"I6",[],[],[224],[247,248],"数字化 农业社会化服务 农业现代化","熵值TOPSIS 农业现代化指数","数字化农业社会化服务农业现代化-5457","10.13733\u002Fj.jcam.issn.2095-5553.2026.10.031",{"doi":250,"openalex_id":9,"authors":252,"venue":9,"cited_by_count":74,"oa_url":9,"card":253,"direction":80,"ingested_from":258},[],{"tldr":254,"method":255,"finding":256,"direction":80,"opportunity":257},"用省级面板数据检验数字化对农业现代化的促进机制。","2013—2023年30省面板数据，熵值TOPSIS测度，双向固定效应模型。","数字化显著促进农业现代化，经市场化传导，社会化服务起调节作用，主产区不显著。","可探究粮食主产区数字化效应不显著的成因，及社会化服务与数字化的协同机制。","agent","2026-10-21T00:10:07.928719Z",{"id":261,"title":262,"url":263,"summary":264,"summary_zh":265,"content":9,"source_name":10,"source_url":263,"published_at":266,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":267,"score_detail":268,"sources":271,"tags":273,"primary_topic":277,"secondary_topics":278,"classification":279,"search_phrases":295,"slug":298,"view_count":74,"doi":299,"paper":300,"created_at":314},4868,"Farmers market as public quick commerce infrastructure: a conceptual policy framework for digital transformation","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1966579","The rapid digitalization of food retail through private quick commerce platforms has transformed urban food consumption patterns in India.

This study suggests a strategic rethinking of Farmers Market as a public quick commerce infrastructure layer, incorporating digital marketplaces, hyperlocal logistics and cooperative governance to boost farmer market competitiveness and promote public value, food system resilience and equitable digital market access. In this study, the Farmers Market Digital Platform model is developed by applying the conceptual policy design approach to convert the Farmers Market platform into a decentralized public quick commerce network. This study identifies the institutional, technological and governance reforms necessary to support the digital transformation of farmer markets using publicly governed digital infrastructure. This reorientation of Farmers Market to public digital infrastructure could form the policy roadmap for platformization of agriculture in Tamil Nadu, which would benefit small farmers, urban consumers, and municipalities and help alleviate inefficiencies in supply chains. As a conceptual policy framework, the proposed model has not been empirically tested and requires future pilot implementation and validation before adoption. The study contributes to the evolving literature on agricultural digitalization by offering a vision for the potential redesign of existing public agricultural markets as digitally enabled public service infrastructure, which can enhance farmer welfare and urban food system resilience.","印度食品零售通过私营即时商务平台的快速数字化，已改变了城市食品消费模式。尽管在数字基础设施方面已有投入，泰米尔纳德邦的“乌扎瓦尔桑代”（Uzhavar Sandhai，即农民市场）——一种农民对消费者的直接营销体系——仍局限于传统的实体市场。本研究建议对农民市场进行战略性的重新思考，将其打造为公共即时商务基础设施层，融合数字市场、超本地物流与合作治理，以提升农民市场的竞争力，并促进公共价值、食物系统韧性以及公平的数字市场准入。本研究运用概念性政策设计方法，构建了农民市场数字平台模型，将农民市场平台转化为去中心化的公共即时商务网络。本研究识别了支持农民市场数字化转型所必需的制度、技术与治理改革，以依托公共治理的数字基础设施加以推进。将农民市场重新定位为公共数字基础设施，可为泰米尔纳德邦农业的平台化提供政策路线图，惠及小农户、城市消费者和市政当局，并有助于缓解供应链中的低效问题。作为一个概念性政策框架，所提出的模型尚未经过实证检验，在采纳之前需要未来的试点实施与验证。本研究为农业数字化领域不断发展的文献作出了贡献，提出了一种愿景，即把现有公共农业市场重新设计为数字赋能的公共服务基础设施，从而提升农民福利与城市食物系统韧性。","2026-10-13T00:00:00Z",76,{"impact":269,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":270},16,"提出将农民市场重构为公共即时零售数字基础设施的政策框架，视角新颖但属概念性研究、未经实证检验，对国内农业数字化政策设计有借鉴价值。",[272],{"name":10,"url":263},[224,274,30,275,276],"农产品流通","农业平台化","公共数字基础设施",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":280},{"candidates":281,"agricultural_evidence":47},[282,286,291],{"code":33,"score":118,"supported":47,"title":283,"abstract":284,"tags":285},[],[50],[30],{"code":287,"score":22,"supported":14,"title":288,"abstract":289,"tags":290},"E5",[],[],[274],{"code":242,"score":22,"supported":14,"title":292,"abstract":293,"tags":294},[],[],[224],[296,297],"Uzhavar Sandhai 农民市场","Tamil Nadu 农业数字化","UzhavarSandhai农民市场-4868","10.3389\u002Ffsufs.2026.1966579",{"doi":299,"openalex_id":301,"authors":302,"venue":10,"cited_by_count":74,"oa_url":308,"card":309,"direction":80,"ingested_from":82},"W7221594564",[303,305],{"name":304,"orcid":9},"Arunachalam Panchatcharam SriVidhya",{"name":306,"orcid":307},"Paul J.

Although previous studies have examined the effects of ASS on agricultural productivity, farm income, and individual input use, it remains unclear whether ASS improve household-level agricultural eco-economic efficiency (AEE), which jointly accounts for economic output, resource use, and environmental costs. Evidence is also limited regarding the factor-allocation channels and production conditions underlying this relationship. Using survey data from 5,992 grain-producing households across 14 provinces in China, this study examines household-level AEE and examines its relationship with ASS adoption using OLS and an instrumental-variable two-stage least squares specification. The results indicate that: (1) ASS adoption is positively associated with grain farmers’ AEE; (2) the estimated relationship varies across farm sizes and crop types, with a more pronounced positive estimate among farmers operating at least 2 ha, but a negative estimate among wheat-growing households; and (3) ASS adoption is associated with a lower share of fertilizer and pesticide expenditure in total variable production costs, whereas no statistically significant labor-reallocation channel is identified. These findings suggest that ASS policies should improve service quality, reduce smallholders’ barriers to service access, develop crop- and production-stage-specific service packages, and promote more precise management of agricultural inputs.","发展农业社会化服务（agricultural socialized services，ASS）并推动粮食绿色低碳生产，是中国农业现代化的重要组成部分。尽管已有研究考察了ASS对农业生产力、农户收入及单项投入品使用的影响，但ASS是否能够提升农户层面的农业生态经济效率（agricultural eco-economic efficiency，AEE）——该效率综合考量经济产出、资源利用与环境成本——仍不明确。关于这一关系背后的要素配置渠道和生产条件，现有证据也较为有限。本研究利用中国14个省份5 992户粮食种植户的调查数据，测度农户层面的AEE，并采用OLS和工具变量两阶段最小二乘（IV-2SLS）方法考察其与ASS采纳的关系。结果表明：（1）ASS采纳与粮农AEE呈正相关；（2）这一估计关系因经营规模和作物类型而异，在经营面积不低于2公顷的农户中正向估计更为显著，但在小麦种植户中呈负向估计；（3）ASS采纳与肥料和农药支出在总可变生产成本中占比下降相关，而未发现统计上显著的劳动力再配置渠道。上述发现表明，ASS政策应提升服务质量，降低小农户获取服务的门槛，开发针对特定作物和生产环节的服务包，并推动农业投入品更为精准的管理。","2026-10-09T00:00:00Z",81,{"impact":96,"substance":97,"depth":96,"authority":323,"freshness":21,"relevant":22,"comment":398},"基于14省5992户粮农调查的实证研究，方法规范、数据扎实，结论对农业社会化服务政策有参考价值，但属学术论文，公共传播性有限。",[400],{"name":10,"url":392},[402,28,403,404,405],"农业绿色发展","农户调查","粮食生产","生态经济效率",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":409},{"candidates":410,"agricultural_evidence":47},[411,415,422,429,436,440,446,452,457,461,466],{"code":33,"score":98,"supported":47,"title":412,"abstract":413,"tags":414},[],[238,50],[28,403],{"code":416,"score":85,"supported":47,"title":417,"abstract":418,"tags":421},"A2",[],[419,420],"小麦","wheat",[],{"code":423,"score":85,"supported":47,"title":424,"abstract":425,"tags":428},"F3",[],[426,427],"肥料","fertilizer",[],{"code":430,"score":85,"supported":47,"title":431,"abstract":432,"tags":435},"F4",[],[433,434],"农药","pesticide",[],{"code":182,"score":85,"supported":47,"title":437,"abstract":438,"tags":439},[],[168,233],[],{"code":441,"score":188,"supported":47,"title":442,"abstract":443,"tags":445},"G6",[],[444],"农户收入",[],{"code":447,"score":188,"supported":47,"title":448,"abstract":449,"tags":451},"H6",[],[450],"农业生态",[],{"code":453,"score":22,"supported":14,"title":454,"abstract":455,"tags":456},"A",[],[],[404],{"code":369,"score":22,"supported":14,"title":458,"abstract":459,"tags":460},[],[],[404],{"code":462,"score":22,"supported":14,"title":463,"abstract":464,"tags":465},"H4",[],[],[402],{"code":187,"score":22,"supported":14,"title":467,"abstract":468,"tags":469},[],[],[402],[471,472],"农业社会化服务 粮食 生态经济效率","农户 化肥农药 投入","农业社会化服务粮食生态经济效率-4557","10.3389\u002Ffsufs.2026.1880279",{"doi":474,"openalex_id":476,"authors":477,"venue":10,"cited_by_count":74,"oa_url":482,"card":483,"direction":487,"ingested_from":82},"W7221161337",[478,480],{"name":479,"orcid":9},"Wensu Tang",{"name":481,"orcid":9},"Xiaohui Li","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1880279\u002Fpdf",{"tldr":484,"method":485,"finding":486,"direction":487,"opportunity":488},"基于14省5992户粮农调查，评估农业社会化服务对农户农业生态经济效率的影响。","OLS与工具变量两阶段最小二乘法，使用14省粮食种植户调查数据。","农业社会化服务提升生态经济效率，规模≥2公顷更明显，小麦户为负；降低化肥农药成本占比。","农业绿色发展与碳","可探究社会化服务对小麦户负效应的成因，及分作物分环节服务包的环境经济协同机制。","2026-10-10T23:30:06.258239Z"]
