In 2009, business accounted for 75% of R&D funding in Japan, 73% in South Korea, 72% in China, 67% in Germany, and 60% in the US, whose companies are the largest R&D investors in terms of absolute purchasing power, spending more than twice as much as Japanese businesses. But business investment as a share of GDP has changed very little in the US over the last decade, while it has risen rapidly in many other countries, including China, Singapore, South Korea, and Israel.
