From the Report:
Five states—California, Massachusetts, Michigan, Texas, and Washington—accounted for half of the research and development paid for and performed by companies in the United States in 2013, according to estimates from the 2013 Business R&D and Innovation Survey (BRDIS) from the National Science Foundation’s National Center for Science and Engineering Statistics.
Companies performed $265 billion of R&D paid for by their own company expenses in the United States in 2013, of which $255 billion could be attributed to one of the 50 states or the District of Columbia.
Not included in these figures but discussed at the end of this InfoBrief is R&D performed by companies but paid for by others, such as the federal government and other customers or business partners.
