【 摘 要 】

This report presents new evidence on industry concentration trends in Europe and in North America. It uses two novel data sources: representative firm-level concentration measures from the OECD MultiProd project, and business-group-level concentration measures using matched Orbis-Worldscope-Zephyr data. Based on the MultiProd data, it finds that between 2001 and 2012 the average industry across 10 European economies saw a 2-3-percentage-point increase in the share of the 10% largest companies in industry sales. Using the Orbis-Worldscope-Zephyr data, it documents a clear increase in industry concentration in Europe as well as in North America between 2000 and 2014 of the order of 4-8 percentage points for the average industry. Over the period, about 3 out of 4 (2-digit) industries in each region saw their concentration increase. The increase is observed for both manufacturing and non-financial services and is not driven by digital-intensive sectors.
