OECD Compendium of Productivity Indicators 2018

This report presents a comprehensive overview of recent and longer-term trends in productivity levels and growth in OECD countries, accession countries, key partners and some G20 countries. It includes measures of labour productivity, capital productivity and multifactor productivity, as well as indicators of international competitiveness.
Productivity by enterprise size
Many examples of productivity analyses typically focus on relatively aggregated industries, masking the heterogeneity in productivity among firms within the same sector and, in particular, the contribution of SMEs, recognised as important drivers of growth as they scale-up. In this sense, firm heterogeneity matters for productivity. To the extent that large firms can exploit increasing returns to scale, productivity tends to increase with firm size. However, new small firms are often found to spur aggregate productivity growth as they enter with new technologies and stimulate productivity-enhancing changes by incumbents.
