Commentary: Considerable research, including from ITIF, has shown that STEM immigrants play an important role in driving invention and innovation. A new study confirms this, finding that countries are 25 to 60 percent more likely to gain advantage in patenting in certain technologies, given a twofold increase in the number of foreign inventors from nations that specialize in those same technologies.
The authors write, “Our results generalize the evidence of previous studies that show how migrant inventors ‘import’ knowledge from their home countries, which translates into higher patenting in the receiving countries. We interpret these results as tangible evidence of migrants facilitating the technology-specific diffusion of knowledge across nations.”
