ABSTRACT

This paper provides an original empirical analysis of the European regional production network, making use of the interregional world input-output database. Similar to the concept of key sectors, a network analysis of key regions and key region-sectors of the EU in the global value chains (GVC) is carried out, taking into account both direct and indirect linkages. Additionally, a clustering analysis is performed to indicate the existence of highly interconnected groups of regions and the polarized structure of the European value chain network. The analysis is extended to quantify implications of Brexit, showing the relative vulnerability of the most internationalized regions and the differentiated sectoral impact according to the geographical origin, as London would mostly affect (tourism and financial) services, whereas the rest of the UK regions would mainly affect manufacturing activities. The findings suggest the considerable heterogeneity of European value chains as a result of varying levels of urban hierarchy, trade specialization between and within countries as well as sectoral concentration of regional economies. The empirical findings can provide valuable policy insights for supporting coordinated economic strategies to enhance regional competitiveness, development and cohesion, and reduce trade imbalances and spatial inequalities in the EU.

摘要

本文利用跨区域的世界投入产出数据库，对欧洲区域生产网络进行了原始的实证分析。与关键部门的概念类似，对欧盟在全球价值链 (GVC) 中的关键区域和关键区域部门进行了网络分析，同时考虑了直接和间接联系。此外，还进行了聚类分析，以表明存在高度相互关联的区域组和欧洲价值链网络的两极分化结构。该分析扩展到量化英国退欧的影响，显示最国际化地区的相对脆弱性以及根据地理起源的不同部门影响，因为伦敦将主要影响（旅游和金融）服务，而英国其他地区将主要影响制造业活动。调查结果表明，由于城市等级制度、国家之间和国家内部的贸易专业化以及区域经济部门集中程度不同，欧洲价值链存在相当大的异质性。实证结果可以为支持协调经济战略提供宝贵的政策见解，以提高区域竞争力、发展和凝聚力，并减少欧盟的贸易不平衡和空间不平等。
