Abstract: What do Japanese firms achieve by R&D investment? The paper deals with this by reviewing the previous research on the relationship between R&D investment and company performance. The available observations are not decisive, but they suggest that relative R&D performance has declined.The paper also discusses the factors affecting it. As one of the recent characteristics of technology strategy of Japanese firms, there is some evidence of greater reliance on internal R&D since mid 1980s. If true, it probably did hurt to R&D performance.
