本文以1995-2006年的55个国家为样本，实证检验了双边贸易模式与国际技术溢出的关系。技术溢出是通过使用美国专利和商标局的专利引用数据来衡量的。本文的主要贡献是提供了新的证据表明，技术溢出的大小显着不同，根据双边贸易模式。特别是，水平型产业内贸易的技术溢出效应大于垂直型产业内贸易，而产业间贸易的技术溢出效应最小。鉴于技术先进国家之间的贸易在水平产业内贸易中所占的比例高于其他国家之间的贸易，我们的研究结果表明，贸易可能会扩大而不是缩小技术先进国家和欠发达国家之间的技术差距。
In this paper, we empirically examine the relationship between bilateral trade patterns and international technology spillovers for a sample of 55 countries during 1995–2006. Technology spillovers are measured by using patent citation data taken from the United States Patent and Trademark Office. The main contribution of this paper is to provide new evidence that the size of technology spillovers significantly varies according to bilateral trade patterns. In particular, horizontal intra-industry trade is associated with larger technology spillovers than vertical intra-industry trade, and the size of technology spillovers is smallest when the trade pattern is inter-industry trade. Given the fact that trade between technologically advanced countries has a higher share of horizontal intra-industry trade than trade between other combinations of countries, our findings suggest that trade may enlarge, rather than narrow, the technology gap between technologically advanced and less-advanced countries.
