北京交通大学学报（社会科学版） 2024年第1期23卷 63-72页

作者：李连发北京大学经济学院北京100871

2017年以来,全球通货膨胀出现分化现象,这是自20世纪70年代布雷顿森林体系崩溃后少见的现象。逆全球化是当前全球通胀分化的主要原因之一。本文选取具有代表性的发达经济体的通胀情况进行分析,以此参照对比其与美国及其与中国通胀变化... 详细信息

2017年以来,全球通货膨胀出现分化现象,这是自20世纪70年代布雷顿森林体系崩溃后少见的现象。逆全球化是当前全球通胀分化的主要原因之一。本文选取具有代表性的发达经济体的通胀情况进行分析,以此参照对比其与美国及其与中国通胀变化分化的情况。研究时间范围为2017年2月—2023年10月,涵盖两个阶段,涉及八个国家。采用协整检验和主成分分析发现,中国和美国是全球通胀分化的重要两极,主要发达经济体追随美国。中国未来面临逆全球化挑战的严峻程度和不确定性呈现上升趋势。我国应以“进”促“稳”,稳中求进,先立后破;研究把握主要发达国家在现有国际经济秩序中发挥主导作用的系统性的活动规律,探索中国在现有国际经济秩序中发挥更大作用、确保自身经济高水平安全发展的有效路径和方法。

物流是实体经济的“筋络”,连接生产与消费、内贸与外贸。有效降低社会物流成本是增强产业核心竞争力、提升经济运行效率的重要举措。当前我国社会物流成本较高,这是我国经济结构、物流业水平、供应链水平、市场效率等因素综合作用的结果:一方面,我国服务业占比低,工业占比高,且多数产品附加值较低,不利于物流费用的降低和产品所对应GDP的增加,影响社会物流总费用与GDP比率的降低;另一方面,我国综合运输体系尚未完全建立,社会库存量大周转慢,物流基础设施不完善且投入不足,物流服务运作主体仍有缺陷,税费高且不统一,产学研一体化体系尚未形成,行业协会合作欠缺,不利于科技赋能和物流业水平、供应链水平、市场效率提升,导致保管和管理费用居高不下,影响社会物流总费用与GDP比率的降低。社会物流成本是国家经济社会发展成本重要的组成部分,通常包括运输成本、保管成本、管理成本三个部分。降低社会物流成本是一项系统工程,切忌单纯从物流看物流,要着眼国民经济全局,通过发展新质生产力、改造物流供应链、推动物流业数智化转型、提升产业链供应链现代化水平、深化市场化改革,着力降低经济结构性物流成本、组织模式性物流成本、运行性物流成本、管理制度性物流成本,四者缺一不可。其中,发展新质生产力、推动物流业进行供应链改造和数智化升级,是降低社会物流成本的必由之路;打造创新力更强、附加值更高、更安全可靠的产业链供应链,是降低物流成本的根本之策;促进物流与供应链制度型开放、深化供给侧结构性改革、构建物流统一大市场,是降低物流成本的制度性保障。此外,还要加强物流与供应链绩效考核,增强物流成本核算意识。
