Innovation in the United States, once a hallmark of economic success, finds itself resting on an increasingly weak foundation, according to an article in The New York Times. The author, Eduardo Porter, suggests that two trends – increased international competition and a stagnant R&D-to-GDP ratio – pose key challenges for the U.S. First, government funding for basic research continues to fall and is politically vulnerable. Second, evidence suggests that American corporations are walking away from basic science as well. Each of these challenges, Porter notes, bodes poorly for American progress. Using a variety of data sources, this Digest series provides a long-term analysis to assess how basic research has changed over time within the larger context of research and development in the United States.

The second in SSTI’s series on basic research, this article focuses on the ways that the funding sources of R&D and basic research have changed over time. Ultimately, the nature of basic research – long horizons, unknown rewards, and high costs – indicates why some sectors, namely the private sector, may seek shorter term options. A better understanding of the changing nature of funding sources for basic research may be useful in understanding the current state of research and development in the U.S.

Using the latest data update of the National Science Foundation’s National Patterns of R&D Resources series, this article, the third and final of SSTI’s series on basic research, describes how the performers of R&D and basic research in the U.S. have changed over time.
