These features make food supply chains particularly vulnerable to external shocks, making the enhancement of supply chain resilience essential for safeguarding food safety and industrial and supply chain security. Using a sample of food firms listed on the Shanghai and Shenzhen A-share markets from 2009 to 2024, we systematically examine the effect of digital technology adoption on supply chain resilience, its potential channels, and heterogeneous effects. First, digital technology adoption significantly enhances the supply chain resilience of food firms. Second, digital technology adoption is significantly associated with greater information transparency, weaker financing constraints, and lower supply chain concentration. Third, this resilience-enhancing effect is more pronounced among firms facing lower environmental uncertainty, firms with stronger corporate innovation capability, and firms located in regions with a higher level of regional marketization. Focusing on the unique context of the food industry, we examine the potential channels and heterogeneous effects of digital technology adoption and provide micro-level empirical evidence for advancing the digital transformation of food firms, safeguarding food safety, and maintaining stable supply.","作为关乎国计民生的重要产业，食品产业的供应链具有原料易腐、季节性显著、安全标准严格、链条长、参与主体高度分散等特征。这些特征使食品供应链更易受到外部冲击，因此提升供应链韧性对于保障食品安全和产业链供应链安全至关重要。本文以2009—2024年沪深A股上市食品企业为样本，系统考察数字技术应用对供应链韧性的影响、潜在渠道及异质性效应。第一，数字技术应用显著提升了食品企业的供应链韧性。第二，数字技术应用与更高的信息透明度、更弱的融资约束和更低的供应链集中度显著相关。第三，这种韧性提升效应在环境不确定性较低的企业、创新能力较强的企业以及所在地区市场化水平较高的企业中更为明显。本文聚焦食品产业的独特情境，考察数字技术应用的潜在渠道和异质性效应，为推进食品企业数字化转型、保障食品安全和维持供应稳定提供微观层面的经验证据。",null,"Frontiers in Sustainable Food Systems","2026-09-18T00:00:00Z","论文",10,false,80,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,22,13,9,1,"基于2009-2024年A股食品企业样本的实证研究，为农业食品行业数字化转型与供应链安全提供微观证据，方法规范、结论有政策参考价值。",[24],{"name":10,"url":6},[26,27,28,29,30],"数字农业","供应链韧性","数字化转型","农业企业","食品供应链",[32,33],"食品企业 数字化转型 供应链韧性","A股食品企业 数字技术 供应链","食品企业数字化转型供应链韧性-2921",0,"10.3389\u002Ffsufs.2026.1930717",{"doi":36,"openalex_id":38,"authors":39,"venue":10,"cited_by_count":35,"oa_url":6,"card":45,"direction":49,"ingested_from":51},"W7213555796",[40,43],{"name":41,"orcid":42},"Meihui Li","https:\u002F\u002Forcid.org\u002F0009-0004-2665-2629",{"name":44,"orcid":9},"Yuechao Zhu",{"tldr":46,"method":47,"finding":48,"direction":49,"opportunity":50},"基于2009-2024年中国A股食品上市公司，实证检验数字技术采用对供应链韧性的影响及机制。","使用沪深A股食品企业面板数据，实证分析数字技术采用与供应链韧性的关系。","数字技术采用显著提升食品企业供应链韧性，通过提高信息透明度、缓解融资约束和降低供应链集中度实现。","数字乡村与农业信息化","可探究数字技术不同维度对食品供应链韧性的差异化影响，以及环境不确定性的调节机制。","openalex","2026-09-19T23:30:08.651264Z",{"total":54,"page":21,"page_size":54,"items":55},6,[56,100,124,167,212,256],{"id":57,"title":58,"url":59,"summary":60,"summary_zh":61,"content":9,"source_name":62,"source_url":59,"published_at":63,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":64,"score_detail":65,"sources":72,"tags":74,"search_phrases":77,"slug":80,"view_count":35,"doi":81,"paper":82,"created_at":99},1416,"THE IMPACT OF DIGITAL TECHNOLOGIES ON THE INNOVATIVE DEVELOPMENT OF AGRICULTURAL ENTERPRISES","https:\u002F\u002Fdoi.org\u002F10.32782\u002Finfrastruct90-32","The article examines the impact of digital technologies on the innovative development of agricultural enterprises in the context of economic digitalization and Industry 4.0.

However, conventional pulse-amplitude modulation (PAM) fluorometers are primarily designed for point measurements and are not suitable for long-term monitoring while attached to intact leaves. Here, we developed Sensor-PAM, a wearable chlorophyll fluorescence measurement system capable of continuously monitoring photosynthetic dynamics from the abaxial side of a leaf. The system combines a commercially available color sensor with blue LEDs in a compact, low-cost optical design to perform PAM measurements. Chlorophyll fluorescence measured from the abaxial leaf surface showed a strong correlation with conventional adaxial measurements and accurately reflected changes in photosynthetic performance induced by chilling and high-light stress. Measurements obtained using Sensor-PAM also showed good agreement with those from a commercial PAM fluorometer across diverse plant species. Furthermore, the wearable system enabled continuous monitoring of the effective quantum yield of photosystem II [Y(II)] from the same position on the same strawberry leaf for three days under both greenhouse and outdoor conditions, successfully capturing photosynthetic responses to changing irradiance and temperature in real time. These findings establish Sensor-PAM as a wearable platform for continuous chlorophyll fluorescence monitoring, extending conventional PAM fluorometry from point-based measurements to long-term monitoring of photosynthetic dynamics under natural environmental conditions.","连续监测光合性能对于理解植物对波动环境的响应至关重要，在植物生理学、田间表型分析和数字农业中具有重要应用。然而，传统的脉冲振幅调制（PAM）荧光仪主要设计用于单点测量，不适合在附着于完整叶片的情况下进行长期监测。在此，我们开发了Sensor-PAM，一种可穿戴叶绿素荧光测量系统，能够从叶片远轴面连续监测光合动态。该系统将市售颜色传感器与蓝色LED相结合，采用紧凑、低成本的光学设计来执行PAM测量。从叶片远轴面测得的叶绿素荧光与传统近轴面测量结果高度相关，并准确反映了低温胁迫和高光胁迫引起的光合性能变化。使用Sensor-PAM获得的测量结果在不同植物物种中也与商用PAM荧光仪的结果吻合良好。此外，该可穿戴系统能够在温室和户外条件下，对同一片草莓叶片同一位置连续三天监测光系统II有效量子产率[Y(II)]，成功实时捕捉了光合作用对光照和温度变化的响应。这些发现确立了Sensor-PAM作为一种可穿戴叶绿素荧光监测平台，将传统PAM荧光测定从单点测量扩展到自然环境下光合动态的长期监测。","bioRxiv (Cold Spring Harbor Laboratory)",81,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":13,"relevant":21,"comment":133},"可穿戴叶绿素荧光监测系统实现叶片光合动态连续监测，方法新颖、数据扎实，对作物表型与数字农业有实用价值，值得进入每日精选。",[135],{"name":130,"url":127},[26,75,137,138,139],"叶绿素荧光","可穿戴传感器","光合表型",[141,142],"可穿戴传感器 叶绿素荧光 光合表型 数字农业","可穿戴传感器 叶绿素荧光","可穿戴传感器叶绿素荧光光合表型数字农业-2782","10.64898\u002F2026.09.12.751108",{"doi":144,"openalex_id":146,"authors":147,"venue":130,"cited_by_count":35,"oa_url":127,"card":160,"direction":164,"ingested_from":51},"W7213448370",[148,151,154,157],{"name":149,"orcid":150},"Ko‐ichiro Miyamoto","https:\u002F\u002Forcid.org\u002F0000-0001-7889-6714",{"name":152,"orcid":153},"Kentaro Ifuku","https:\u002F\u002Forcid.org\u002F0000-0003-0241-8008",{"name":155,"orcid":156},"Tatsuo Yoshinobu","https:\u002F\u002Forcid.org\u002F0000-0001-7993-716X",{"name":158,"orcid":159},"Kaori Kohzuma","https:\u002F\u002Forcid.org\u002F0000-0003-3899-543X",{"tldr":161,"method":162,"finding":163,"direction":164,"opportunity":165},"开发了可穿戴叶绿素荧光系统Sensor-PAM，实现叶片背面光合动态连续监测。","低成本颜色传感器与蓝光LED集成，进行PAM测量并验证。","背面测量与常规正面测量强相关，可连续三天监测草莓叶片Y(II)动态。","农业遥感与作物表型","可穿戴荧光传感器为田间高通量表型提供新手段，可探索多物种长期监测与数据融合。","2026-09-17T23:30:29.467723Z",{"id":168,"title":169,"url":170,"summary":171,"summary_zh":172,"content":9,"source_name":173,"source_url":170,"published_at":106,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":174,"score_detail":175,"sources":179,"tags":181,"search_phrases":186,"slug":189,"view_count":35,"doi":190,"paper":191,"created_at":211},2766,"Profiles of Structural Exclusion in the Twin Transition: Ideal Types, Political Disaffection, and Participatory Governance","https:\u002F\u002Fdoi.org\u002F10.17645\u002Fpag.12501","This article analyses how the simultaneous pursuit of green decarbonisation and digital transformation—the twin transition—generates disproportionate structural burdens on marginalised social groups.

Each profile identifies the mechanisms through which green and digital policies impose unequal costs on vulnerable groups, examining the resulting dynamics of institutional disaffection, potential political radicalisation, and common structural patterns. Comparative analysis identifies four recurring exclusion mechanisms—the upfront cost barrier, the digital literacy gateway, the geographic penalty, and knowledge disqualification—tracing a common pathway from structural exclusion to political disaffection.

This narrower dimension of food security is termed food-supply resilience. This study treats the Regional Comprehensive Economic Partnership (RCEP) as a policy-relevant regional supply space and examines whether its agri-food networks contain short-run callable capacity for import-vulnerable economies. The analysis advances the claim that connectivity is not capacity: trade links support resilience only when they connect vulnerable importers to suppliers with callable surplus, stable ties, and usable access. Methods This study constructs 126 commodity-year networks for six agri-food categories over 2001–2021 using CEPII-BACI trade data, with FAOSTAT quantities used as an independent cross-source check. Import vulnerability is measured through supplier dependence, concentration, and tie stability. Supplier substitution is assessed through regional supplier persistence, lower-bound callable surplus, gross-export upper-bound coverage, and shock-specific access conditions. Post-2021 observations are used as descriptive monitoring checks rather than as agreement-effect estimates. Results Regional Comprehensive Economic Partnership agri-food networks became more connected, but resilience profiles diverged by commodity. Rice was the only distributed-supplier profile. Milk-powder dairy and palm oil combined large regional surplus with exporter cores concentrated around New Zealand and Australia, and Indonesia and Malaysia, respectively. Soybean and pork remained weak regional-substitution cases, while selected tropical and subtropical fruit was retained only as a compositional regional-trade profile. China showed a centrality paradox: it became more central where regional alternatives already existed but remained peripheral in soybean and pork, where extra-regional dependence mattered most. Lower-bound and gross-export upper-bound checks confirmed pervasive regional substitution gaps in soybean and pork across eligible importer profiles, not only for China. The Philippines-rice case showed the contrasting profile of an import-vulnerable economy backed by substantial regional surplus. Discussion The shock episodes support the diagnostic. Rice export restrictions, Indonesia’s palm-oil export ban, and the African swine fever pork shock show that regional networks support food-supply resilience only when vulnerable importers are connected to suppliers with callable surplus, stable ties, and usable access. Regional agreements can reduce frictions and improve coordination, but they do not automatically create deployable supply. Food-security governance should therefore monitor commodity-importer vulnerability, callable surplus, gross-export upper bounds, tie persistence, and access readiness rather than treating network connectivity as resilience.","引言 政策、市场和生物安全冲击检验了区域贸易网络在既有采购渠道中断时能否维持实体粮食可获得性。这一较窄维度的粮食安全被称为粮食供应韧性。本研究将《区域全面经济伙伴关系协定》（RCEP）视为具有政策相关性的区域供应空间，并考察其农食网络是否对进口脆弱型经济体包含短期可调用能力。分析提出，连通性不等于能力：贸易联系只有在将脆弱进口方连接到拥有可调用盈余、稳定联系和可用准入的供应方时，才能支撑韧性。方法 本研究利用CEPII-BACI贸易数据构建了2001—2021年间六大农食类别的126个商品—年份网络，并使用FAOSTAT数量数据作为独立的跨来源校验。进口脆弱性通过供应方依赖、集中度和联系稳定性来衡量。供应方替代通过区域供应方持续性、下限可调用盈余、总出口上限覆盖率和冲击特定准入条件来评估。2021年后的观察结果被用作描述性监测检查，而非协定效应估计。结果 RCEP农食网络变得更为连通，但韧性特征因商品而异。大米是唯一呈现分布式供应方特征的商品。奶粉乳制品和棕榈油分别将大规模区域盈余与集中在新西兰和澳大利亚、印度尼西亚和马来西亚的出口核心相结合。大豆和猪肉仍是区域替代较弱的案例，而部分热带和亚热带水果仅作为构成性区域贸易特征得以保留。中国表现出中心性悖论：在区域替代品已经存在的地方，中国变得更为中心，但在大豆和猪肉这些域外依赖最为重要的领域，中国仍处于边缘。下限和总出口上限检查证实，在符合条件的进口方特征中，大豆和猪肉普遍存在区域替代缺口，不仅限于中国。菲律宾—大米案例则展示了另一种特征：一个进口脆弱型经济体得到大量区域盈余的支撑。讨论 冲击事件支持了这一诊断。大米出口限制、印度尼西亚棕榈油出口禁令和非洲猪瘟猪肉冲击表明，区域网络支撑粮食供应韧性","2026-09-16T00:00:00Z",{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":220},"基于CEPII-BACI与FAOSTAT构建126个商品-年份网络，提出“连通性不等于可调用产能”的诊断框架，对大豆、猪肉等进口脆弱品类有实质结论，但属学术论文，产业落地影响有限。",[222],{"name":10,"url":215},[224,225,226,27,227,228],"粮食安全","大豆","RCEP","农产品贸易","猪肉",[230,231],"供应链韧性 农产品贸易 粮食安全 大豆","供应链韧性 农产品贸易","供应链韧性农产品贸易粮食安全大豆-2762","10.3389\u002Ffsufs.2026.1924874",{"doi":233,"openalex_id":235,"authors":236,"venue":10,"cited_by_count":35,"oa_url":249,"card":250,"direction":96,"ingested_from":51},"W7213434130",[237,239,242,244,246],{"name":238,"orcid":9},"Guo Ru",{"name":240,"orcid":241},"Bolu Wei","https:\u002F\u002Forcid.org\u002F0009-0003-4854-2036",{"name":243,"orcid":9},"Mingrong Zeng",{"name":245,"orcid":9},"Pan Liu",{"name":247,"orcid":248},"Bixiang Shi","https:\u002F\u002Forcid.org\u002F0000-0003-2034-1710","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1924874\u002Fpdf",{"tldr":251,"method":252,"finding":253,"direction":96,"opportunity":254},"基于RCEP农食贸易网络，诊断进口脆弱性、供应商替代与短期可调用产能。","用CEPII-BACI 2001–2021年126个商品-年份网络，FAOSTA","RCEP连通性增强但韧性分化，大豆和猪肉普遍存在区域替代缺口。","可构建可调用剩余与准入条件的动态预警模型，识别替代缺口商品。","2026-09-17T23:30:08.362367Z",{"id":257,"title":258,"url":259,"summary":260,"summary_zh":261,"content":9,"source_name":262,"source_url":259,"published_at":263,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":264,"score_detail":265,"sources":267,"tags":269,"search_phrases":272,"slug":275,"view_count":35,"doi":276,"paper":277,"created_at":292},2542,"Discrete Element Method-Based Modeling and Application of Agricultural Materials: A Review","https:\u002F\u002Fdoi.org\u002F10.3390\u002Fagriculture16181958","Discrete element method (DEM) has become an essential tool for analyzing particle-scale behavior and complex interactions in agricultural materials and machinery. This review synthesizes recent advances in DEM-based modeling and applications in agricultural engineering. It systematically examines particle modeling strategies, contact model development, and parameter calibration frameworks for representative materials such as soil, seeds, fertilizers, stalks, and roots. The evolution from simple spherical approximations to multi-sphere, bonded, and 3D scan-based reconstructions is highlighted, along with the shift from classical Hertz–Mindlin models to cohesive, elasto-plastic, and fracture-capable formulations. Calibration methods are traced from empirical assignment to systematic frameworks that integrate design of experiments, response surface methodology, and machine-learning-assisted inverse analysis. These advances in fidelity and accuracy have enabled extensive DEM applications in tillage, seeding, fertilization, and harvesting, with emphasis on equipment optimization, mechanism analysis, and performance prediction. Despite the progress, challenges remain in model standardization, parameter transferability, computational cost, and multiphysics coupling. Future work points to unified modeling frameworks, standardized databases, real-time simulation, and integration with artificial intelligence to support digital agriculture and intelligent machinery. This review aims to serve as a reference for high-fidelity DEM modeling and for advancing the digital transformation of agricultural engineering.","离散元法（DEM）已成为分析农业物料与机械中颗粒尺度行为及复杂相互作用的重要工具。本文综述了基于DEM的建模与农业工程应用的最新进展，系统考察了土壤、种子、肥料、茎秆和根系等代表性物料的颗粒建模策略、接触模型开发及参数标定框架。重点阐述了从简单球形近似到多球体、粘结型及基于三维扫描的重构方法的演变，以及从经典Hertz–Mindlin模型向黏聚、弹塑性及可断裂本构模型的转变。标定方法从经验赋值发展为集成试验设计、响应面法和机器学习辅助反分析的系统框架。这些在保真度和精度方面的进步使得DEM在耕整、播种、施肥和收获等领域得到广泛应用，重点涉及装备优化、机理分析和性能预测。尽管取得了进展，但在模型标准化、参数可迁移性、计算成本和多物理场耦合方面仍存在挑战。未来工作指向统一建模框架、标准化数据库、实时仿真以及与人工智能的融合，以支撑数字农业和智能机械发展。本文旨在为高保真DEM建模及推进农业工程数字化转型提供参考。","Agriculture","2026-09-12T00:00:00Z",76,{"impact":17,"substance":177,"depth":17,"authority":19,"freshness":54,"relevant":21,"comment":266},"系统综述离散元法在农业物料建模与装备优化中的进展，方法学价值高，对智能农机与数字农业有参考意义。",[268],{"name":262,"url":259},[26,75,115,270,271],"农业机械","离散元仿真",[273,274],"农业人工智能 离散元仿真 农业机械 数字农业","农业人工智能 离散元仿真","农业人工智能离散元仿真农业机械数字农业-2542","10.3390\u002Fagriculture16181958",{"doi":276,"openalex_id":278,"authors":279,"venue":262,"cited_by_count":35,"oa_url":259,"card":287,"direction":96,"ingested_from":51},"W7213152558",[280,282,284],{"name":281,"orcid":9},"Xingchi Zhou",{"name":283,"orcid":9},"Yanbin Liu",{"name":285,"orcid":286},"Zhenwei Liang","https:\u002F\u002Forcid.org\u002F0000-0001-6501-4364",{"tldr":288,"method":289,"finding":290,"direction":96,"opportunity":291},"综述农业物料离散元建模的粒子模型、接触模型与参数标定进展及应用。","综述离散元粒子建模、接触模型、标定方法及在耕播收中的应用。","建模从球形向多球\u002F键合\u002F3D重建演进，标定转向机器学习辅助反演。","可探索DEM与AI实时仿真、多物理场耦合及标准化参数数据库构建。","2026-09-15T23:30:36.643241Z"]
