Abstract

What do Japanese manufacturing companies achieve by investing in R&D? Is there no doubt among Japanese managers about the assumption that the more R&D, the better the companies perform? This paper deals with these issues by reviewing the previous research on the relationships between R&D investment and capital investment, profitability and company growth. The available observations we reviewed are not decisive, but they suggest that relative R&D performance of Japanese manufacturing companies has declined. The paper also discusses the possible factors affecting the decline, including the characteristics of technology strategy and R&D management. As one of the recent characteristics of technology strategy of Japanese companies, there is some evidence of greater reliance on internal R&D since mid 1980s. If this is the case, it probably did hurt to their R&D performance.
