aAggregate R&D intensities calculated after converting R&D expenditures and production with 1995 gross domestic product purchasing power parities.
bR&D expenditures in shipbuilding (351) included in other transport (352 and 359).
NOTE: R&D intensity is direct R&D expenditures as percentage of production (gross output).
