Globalization And Knowledge Spillover: International Direct Investment, Exports And Patents
This paper examines the impact of the three main channels of international trade on domestic innovation, namely outward direct investment, Inward Direct Investment (IDI) and exports. The number of Triadic patents serves as a proxy for innovation. The data set contains 37 countries that are considered to be highly competitive in the world market, covering the period 1994 to 2005. The empirical results show that increased exports and outward direct investment are able to stimulate an increase in patent output. In contrast, IDI exhibits a negative relationship with domestic patents.
