Global R&D Spending

"China doubled its spending on research and development between 1995 and 2002, calculated as a percentage of GDP, from 0.6% to 1.2% of GDP. Over the same period, Israel increased its spending from 2.74% to 4.72% of GDP, a ratio higher than that of any OECD country. By comparison, overall spending in OECD countries on research and development rose only moderately in proportional terms, to 2.26% of GDP from 2.09% in 1995, but it declined from its peak in 2001 of 2.28% of GDP."
