The impact of R&D offshoring on the home knowledge production of OECD investing regions
研究了高收入地区向新兴经济体进行研发离岸外包是否与本土知识生产存在互补关系，发现当利用各自比较优势时这种互补性成立。
We investigate the effect of research and development (R&D) offshoring from high-income regions to prominent emerging economies. Specifically, we examine whether there is a complementary relationship between a region’s home and foreign investments in R&D that affects home’s regional knowledge production. Using a theoretical framework based on economic geography and the literature on international knowledge sourcing, we conjecture that high-income regions would have a comparative advantage in high-tech R&D, while emerging economies would have an advantage in medium/low R&D. Complementarity should obtain when the comparative advantages of the geographical areas are utilized. We find overall empirical support for this prediction.
