Since the early 1980s, there has been widespread debate over the impac
ts of rising levels of inward foreign direct investment (FDI) on the U
.S. economy. A frequently noted, but little studied, issue within the
debate is the impact of FDI on U.S. foreign trade, and particularly, o
n the foreign trade of U.S. regions. This study assesses the effects o
f FDI on the manufacturing export performance of U.S. states during th
e period from 1980 to 1991. Results indicate that increased levels of
FDI are positively related to future improvements in state manufacturi
ng export performance.
