摘要
本文在企业异质性分析框架基础上,从理论上探讨了基础设施影响出口技术复杂度的微观机制。在理论分析的基础上,本文使用1995—2004年HS—6分位的跨国数据,分别采用Hausmann et al(2007)和Xu(2007)的方法测算了101个国家的出口技术复杂度,并运用工具变量两阶段最小二乘法和系统GMM方法进行了计量估计。实证结果表明,基础设施稳健地提高了各国的出口技术复杂度。此外,人力资本、贸易开放与FDI也起到了积极作用,自然资源禀赋的影响则恰好相反。
This paper builds up a model to establish the causal link between infrastructure and export technological sophistication in the framework of firm heterogeneity. Furthermore, by using HS-6 digital trade data from 1995-2004, and the methods developed by Hausmann et al（2007） and Xu（2007）, we measure 101 countries＇ export technological sophistication index and empirically test its determinants, whose results strongly support the prediction of the theoretical model. In addition, human capital endowment, trade opening and FDI also play some positive role, while the effect of natural resources is negative.
