Everyone knows that the economic future belongs to those who put technology and innovation to work. One part of the formula for economic success for a high-income economy is active research and development, which then offers spillovers that are typically greater for the national economy than for the world economy as a whole. I\’ve posted here about the arguments for raising R&D spending substantially, and here with a global overview of R&D spending. Dan Steinbock offers some additional perspective in \”American Innovation Under Structural Erosion and Global Pressures,\”
a February 2015 report written for the Information Technology and Innovation Foundation.
Here\’s a picture of the global R&D effort. The horizontal axis shows R&D spending as a share of GDP for various economies. The vertical axis shows scientists and engineers per million people (thus adjusting for population size). The size of the circle for each country is relative to the total number of scientists and engineers: thus, China and India have fewer scientists and engineers per capita, but because of their large populations, the size of their circles is relatively large. The color of the circle shows the region of the world, as given by the key in the upper left of the figure.
Clearly, the U.S. position in global R&D remains fairly strong. But the US lags behind Germany and Japan, among others, in the share of its economy going to R&D. The size of the yellow circles–Japan, South Korea, Taiwan, Singapore, China, Australia, and India–shows that the region with the largest absolute number of scientists and engineers is now the Asia-Pacific area. The U.S. has had a tradition of leading or being close to the lead in most areas of technology. As technological capacities expand around the rest of the world, the U.S. needs to strengthen its ties to the work being done elsewhere, increase the U.S. R&D effort, or both.
Steinbock lays out a number of trends in U.S. R&D. Here are a few that caught my eye. First, the ratio of R&D spending to GDP hasn\’t moved much in the US since the 1960s, hovering around 2.5% of GDP. However, federal support for R&D has been falling by this measure over time, while the nonfederal share has been rising.
