Abstract
This article investigates the relationship between foreign direct investment (FDI, including outward FDI and inward FDI), imports and exports, and product innovation. Our theoretical model predicts that inward FDI, outward FDI, imports, and exports have positive influences on firm innovative activities, which would evaluate the effects of the relative magnitude of different sources on innovation. The empirical results based on the 2003 First Taiwan Technological Innovation Survey confirm three of the proposed hypotheses for the entire sample. However, when focusing on the manufacturing sector, outward FDI, inward FDI, imports, and exports all exhibit strongly positive effects on the determination of conducting product innovation (i.e., the four hypotheses are verified). A consistent trend is that outward FDI has the largest effect on innovation, regardless of the measurement of product innovation and the division of the entir sample, which may imply that in Taiwan a positive effect of " deindustrialization " is to innovate more.
