This paper estimates the effect on innovation of increased market access facilitated by trade liberalization. We use a novel empirical design that exploits tariffcuts during the 1990s, along with detailed data on innovation among firms from 65 different countries. Our results reveal a large effect of tariff cuts on innovation as measured by patent data, suggesting that multilateral liberalization has pro-moted innovation and growth. These effects are not driven by the deterioration of innovation quality, and the results are robust to controlling for changes in the patent system and to industry-wide trends in innovation.

更好、更快、更强：全球创新和贸易自由化

本文估计了贸易自由化促进的增加市场准入对创新的影响。我们使用了一种新颖的实证设计，该设计利用了 1990 年代的关税削减，以及来自 65 个不同国家的公司之间创新的详细数据。我们的结果显示，以专利数据衡量，关税削减对创新有很大影响，表明多边自由化促进了创新和增长。这些影响不是由创新质量的恶化所驱动的，结果对于控制专利制度的变化和全行业的创新趋势是稳健的。
