Much research has tried to measure the competitiveness of territorial units such as countries and subnational regions. We propose new measures of subnational trade competitiveness that reflect the economic focus of regions on their country’s comparative advantage. Our approach starts with data on the revealed comparative advantage of countries at the industry level. We then combine these measures with data on the employment structure of regions to arrive at measures of subnational trade competitiveness. In total, we offer data for 1,212 regions across 62 countries and over a time period of 21 years. In this paper, we introduce our measures and provide descriptive evidence that shows the plausibility
of these measures. We also discuss some of the many research questions that these data can be used to address.
