The United States is giving up ground when it comes to its share of research and development, according to a report released today by the National Science Board, which is part of the National Science Foundation.


Since 2001, says the Science and Engineering Indicators report, the share of the world's R&D performed in the United States has decreased to 30 percent from 37 percent. During the same period, the share of worldwide R&D performed by Asian countries grew to 34 percent from 25 percent. China's global share grew to 15 percent from 4 percent.


The numbers show a "dramatic shift in the global scientific landscape," said Dan Arvizu, director and CEO of the National Renewable Energy Laboratory and chairman of the National Science Board, in a news release.


The shift is due in part to the recognition of national leaders that innovation contributes to national competitiveness, improves living standards and furthers social welfare, the National Science Board said.


Overall, R&D performed as a percentage of gross domestic product was 2.61 percent in 2010, up slightly from 2.48 percent in 2000. Federal agencies, businesses, universities, nonprofit organizations and state agencies spent a total of $375.7 billion on R&D in 2010.


In Iowa, that number was 2 percent in 2010, up from 1.09 percent in 2000. A total of $2.8 billion was spent on R&D in Iowa in 2010.
