The European Commission’s Regional Competitiveness Index (RCI) has measured the major factors of competitiveness every third year since 2010. The top performer in the 2019 edition is the Stockholm region, followed by London and Utrecht in a combined second place. The index uses more than 70 indicators such as governance, infrastructure, health, human capital and labour market and innovation to measure the ability of a region to offer an attractive and sustainable environment for firms and residents comparing 268 European regions. In 2016 Stockholm was in fourth place.
