Is innovation more concentrated in America than economic output?
Core argument: The share of technologies attributed to U.S. origin rises to roughly 60–70% in recent periods, even though the United States accounts for only 20–30% of global GDP.
We observe the rising dominance of American innovation in the late 19th century, coinciding with the US becoming the leading economic power. However, unlike the GDP statistics, while America reached its peak percentage of global GDP in the early 20th century, its total dominance in innovation is a more recent phenomenon. In our dataset, the share of technologies attributed to U.S. origin rises to roughly 60-70% in recent periods, even though only 20 to 30% of global GDP has been American. This highlights how GDP today may be a poor proxy for who is driving GDP growth tomorrow: innovation appears much more concentrated in America than economic activity.
