本文试图研究COVID-19冲击如何通过区域一体化和全球价值链（GVC）影响不同国家。使用EORA数据集的输入输出表，我们的贡献是三倍的。首先，我们从概念上修正了分析投入产出关系的方法，强调了附加值的双边流动与贸易之间的区别，并区分了附加值的生产者和消费者。第二，我们区分这些国家可能受到全球价值链中断影响的供应和需求渠道。第三，我们将这一实证研究应用于一个研究不足的地区，即地中海地区，其特点是参与了几个贸易协定，可能会促进其融入全球价值链。我们的主要研究结果表明，第一，大多数国家的全球价值链后向联系相对大于前向联系。第二，在地中海北方海岸，意大利和法国是增值的净供应国，因为它们生产的被国外吸收的增值多于它们消费的外国增值。第三，我们的研究结果还突出表明，南部海岸伙伴之间的一体化有限，其一体化几乎完全是由与南欧发达国家的联系推动的。
This paper tries to examine how the COVID-19 shock affects different countries through their regional integration and their exposure to Global Value Chains (GVCs). Using input-output tables from the EORA dataset, our contribution is threefold. First, we conceptually revise the approache to analyse input-output relationships and underline the difference between the bilateral flow of value added and trade and distinguish between the producers and consumers of value-added. Second, we distinguish between the supply and demand channels through which these countries can be affected by the disruptions in GVCs. Third, we apply this empirical exercise on an understudied region, namely the Mediterranean region that is characterised by its involvement in several trade agreements that might boost their integration into GVCs. Our main findings show that, first, most of the countries have relatively larger backward GVC linkages than forward ones. Second, in the Northern shore of the Mediterranean, Italy and France are net suppliers of value added since they produce more value-added absorbed abroad than the foreign value-added they consume. Third, our results highlight also the limited integration between Southern shore partners, whose integration is almost completely driven by linkages with Southern European developed countries.
