彭云：中国县域消费突围的特征、困境及路径——基于美团全国县域消费大数据的分析

县域消费作为县域经济的重要组成部分,是全面扩大内需、提振消费的重要发力点。本文借鉴消费三要素分析框架,基于2019-2023 年美团平台涉及的1000 多个县域的消费数据和 1400 余份消费者调查问卷,对当前县域消费的特征、动力、主要困境等进行分析。研究发现,当前县域消费规模逐年扩容,以中青年群体为主力,消费内容趋向多样化、品质化,消费渠道呈现线上化发展趋势。县域消费动力主要源于县域商业供给体系优化、新兴消费业态不断涌现以及在线评价体系等数字技术持续赋能,不断满足和激发消费需求,提升消费体验。...

中国社会科学院世经政所：金融制裁是否会削弱美元霸权-一个基于储备安全成本的分析框架

俄乌冲突爆发后,金融制裁对美元霸权的影响在全球范围内引发争论.文章从储备安全成本视角构建了一个金融制裁影响美元霸权的分析框架,并借助模型进行了理论推演.模型阐释了美国三项典型金融制裁措施给受制裁国带来储备安全成本并促使其调整国际储备的机制:本国实体被列入SDN 清单改变了受制裁国实际交易需求的币种结构、金融机构被禁用 SWIFT增加了受制裁国开展国际支付的摩擦、冻结央行外汇储备减少了受制裁国可用的外储规模.这些都将给受制裁国带来储备安全成本,促使其降低国际储备中的美元份额,增加非主导...

中国社会科学院世经政所：机器人应用与全要素生产率-来自全球生产率分化的经验证据

机器人技术作为赋能高质量发展的新动力,不仅直接影响就业需求,还通过就业替代机制和产业结构机制对各国生产率产生分化影响,导致技术红利难以均等惠及所有国家,不利于缩小各国生产率差距。本文通过理论模型分析,推断机器人对生产率具有积极影响,且“机器换人”是提高全要素生产率的重要渠道。基于多个经济体数据的实证研究结果显示,机器人应用提高了各经济体全要素生产率,但由于高生产率经济体的产业结构与机器人技术的匹配度更高、形成的就业替代效应更强,使其生产率的提升幅度更大,进而总体上加剧了全球生产率分化...
