| 1 | 乡村产业数字化转型升级内涵特征、驱动机制与实现路径显示文摘扎实推动乡村产业数字化转型升级,既是乡村产业发展动能转换的迫切需求,也是促进乡村产业高质量发展的现实需要,更是农业农村现代化发展的必经之路。乡村产业数字化转型升级内涵可分为数字化转型、价值链升级和一二三产业融合三个层次,其所包含的六大主要产业具有不同的数字化转型升级特征。通过构建政府-市场-社会三重驱动理论机制,分析了有为政府制度顶层设计和数字基础设施建设、有效市场资源配置优化和调节作用有效发挥、有力社会发展理念转变和数字普惠协同推进乡村产业数字化转型升级的内外驱动力。以此提出有为政府增长甄别和因势利导,有效市场技术创新和需求导向,有力社会环境营造和人才培育等乡村产业数字化转型升级的实现路径。 | 邱俊杰 BENFICA Rui 余劲 | 2023 | 西北农林科技大学学报(社会科学版)2023，23，5： | 3 |

| 6 | PUBLIC INVESTMENT IN AGRI-FOOD SYSTEM INNOVATION FOR SUSTAINABLE DEVELOPMENT显示文摘Research is essential for improvement of agricultural productivity,resource use and resilience,and for food systems transformation more broadly.This article analyzes the drivers of past agricultural productivity growth in low-and middle-income countries(LMICs)and argues that productivity is not growing fast enough to meet the needs of a global population of 10 billion by 2050.A sustainable transformation of agri-food systems in LMICs will need greater and faster technical change.Higher investment in agri-food R&D is therefore needed to accelerate productivity growth and address the social,economic,nutritional and environmental challenges facing LMICs.Greater and bettertargeted investment in sustainable technologies and climate change mitigation and adaptation will be particularly important to reducing the climate change impacts on agriculture and food security in the coming decades.However,LMICs with small research systems and limited innovation capacity lack the scale and resources to effectively tackle the challenges ahead.Better coordination and a clear articulation of roles and responsibilities among national,subregional,regional and global R&D actors(both from the public and private sectors)are essential to ensuring that scarce financial,human,and infrastructure resources are optimized,duplications minimized,and synergies and complementarities enhanced. | Gert-Jan STADS Alejandro NIN-PRATT Keith WIEBE Timothy BSULSER Rui BENFICA | 2023 | Frontiers of Agricultural Science and Engineering2023，10，1： | 0 |
