摘要：

This study considers the productivity of R&D expenditures on an international and multi-industry basis. Using 1992 data reported by Business Week on 117 companies in the United States, Europe, and Japan, we examined two measures of innovative output, patents and impact-adjusted patents, in relationship to R&D spending. Our results clearly show a decreasing returns to scale of R&D expenditure. Although this pattern holds true regardless of industry or global region, the level of return and rate of decreasing returns vary by both industry and international region.
