Despite Slide in World Share, U.S. Impact Still Looks Strong

摘要

The United States continues to see its share of world science erode, particularly in the face of a steady rise by the collective nations of the Asia Pacific region, but the citation impact of U.S. scientific papers still surpasses the world average by a healthy margin in the major fields of science, according to a new Science Watch survey.rnScience Watch has been monitoring this trend for a dozen years now, most recently in July/August of 2005. On that occasion, as in the graph above, the U.S. percent share of world science was tracked against that of the Asia Pacific bloc and the nations making up the European Union. The current graph adds another three years of data to the last survey, reflecting figures through 2007.
