International Knowledge Spillovers
研究外国知识对国内创新的影响，发现新兴经济体吸收外国知识的障碍显著下降，国际竞争压力增加促进了国内创新。
Abstract How important is foreign knowledge for domestic innovation outcomes? How is this relation shaped by globalization and the attendant intensification of international competition? Our empirical approach extends the previous literature by analyzing a large panel comprising industries in both advanced and emerging economies over the past two decades. We find that barriers to the domestic diffusion of foreign knowledge have fallen significantly for emerging economies. For all countries, and especially for emerging economies, inflows of foreign knowledge have a growing and quantitatively important impact on domestic innovation. Controlling for the amount of domestic R&D, we find evidence that increases in international competitive pressure at the industry level had a positive effect on domestic innovation outcomes.
