This tenth edition of the OECD Science, Technology and Industry (STI) Scoreboard builds on the OECD’s 50 years of indicator development to present major world trends in knowledge and innovation. It analyses a wide set of indicators of science, technology, globalisation and industrial performance in OECD and major non-OECD countries (notably Brazil, the Russian Federation, India, Indonesia, China and South Africa) and includes some experimental indicators that provide insight into new areas of policy interest.

Sectoral specialisation

An economy can be defined as “specialised” if a few sectors account for a relatively large share of the country’s GDP, whereas it is “diversified” if each of a relatively high number of sectors accounts for a small share of GDP. Industrial specialisation or diversification patterns relate to economies’ long-run productivity, resilience to a crisis, investment patterns, innovativeness and performance of firms and sectors. The Hannah-Kay (HK) diversification index captures a country’s full sectoral composition and accounts for the influence of larger sectors. A lower HK corresponds to rising sectoral specialisation. The concentration ratio (CR) index shows the share of value added accounted for by the economy’s top four sectors.
