摘要

摘要 本文旨在研究 2020-2022 年(COVID-19 大流行时期)与 2019 年(大流行前的最后一年)相比,全球价值链(GVC)发生的变化。全球价值链的图示基于以进出口附加值衡量的国际贸易统计数据。本文采用最终需求法,以增值出口和进口来衡量国际贸易,并根据亚洲开发银行(ADB)提供的国家间投入产出表进行计算。世界制造 "这一口号给人留下了深刻印象,但实际上,价值链很少是全球性的。相反,它们是区域性的,有三个中心。2019-2022年,"欧洲工厂"、"亚洲工厂 "和 "美洲工厂 "很容易辨认,因为全球价值链中有三个大型区域供应中心:德国、中国和美国。2020-2022 年与 2019 年相比,以中国为中心的 "亚洲工厂 "在全球价值链中的地位有所提升,而以德国为中心的 "欧洲工厂 "和以美国为中心的 "美洲工厂 "的地位则有所下降。

Global value chains before and in times of the COVID-19 pandemic
Abstract This paper aims to examine the changes in global value chains (GVCs) in the years 2020–2022 (times of the COVID-19 pandemic) compared to 2019 (last year before the pandemic). GVCs are illustrated by diagrams based on the statistics on international trade measured by value-added exports and imports. In this paper, the final demand approach is applied to measure international trade by value-added exports and imports and they were computed based on inter-country input-output tables delivered by the Asian Development Bank (ADB). The catchphrase “Made in the World” makes an impression, but in reality, value chains are rarely global. They are rather regional with three centers. “Factory Europe”, “Factory Asia”, and “Factory America” can easily be identified in the years 2019–2022 as there were three large regional supply hubs in GVCs: Germany, China, and the United States. When the years 2020–2022 were compared to 2019, “Factory Asia” with center in China elevated their position in GVCs at the expense of “Factory Europe” with center in Germany and “Factory America with center in the USA.”
