This study examines the extent to which subnational regions can explain foreign affiliate performance in two host country settings, the United States and China, the world's two largest economies at polar ends of the economic spectrum (i.e., an advanced versus an emerging economy). Our results suggest that the subnational region is significant in explaining foreign affiliate performance, thus confirming its importance as an additional unit of analysis for firm performance. This study also shows that the effects of subnational region are far stronger in China than they are in the United States, thus suggesting that regional differences are more critical in their explanatory power for firm performance in emerging economies than they are in advanced economies.
