The Industrial Linkages and Supply Effects of the U.S. R&D Sector: Comparison with OECD Countries

Abstract

The industrial linkages and supply effects of the U.S. Research and Development (R&D) sector are examined using the input-output approach. Although the U.S. has the highest R&D intensity among major OECD countries, the U.S. R&D sector has relatively low backward and forward linkages to other industrial sectors. Moreover, the supply investment effect of the U.S. R&D sector is the least, showing that the sector is not likely to stimulate the production of the other sectors. The supply shortage effect of the U.S. R&D sector is also the least among the countries. The findings in this study imply that improving the linkages and supply effects of the R&D sector may be more important than increasing only the amount of R&D expenditure in the U.S.
