金融发展与出口技术复杂度提升——基于影响渠道的研究

Financial Development and Improving the Complexity of Export Technology:A Study Based on Impact Channels

根据内生技术进步理论,构建金融发展影响技术进步的理论模型,论证了金融发展通过外商直接投资技术外溢效应和提升研发效率两个渠道促进一国出口品技术含量提升。基于Hausmann提出的出口技术复杂度指标,利用完全国内增加值系数进行修正,得到1995年至2014年45国修正的出口技术复杂度,实证检验了金融发展对出口技术复杂度的影响渠道。结果表明:外商直接投资、研发效率是金融发展影响出口技术复杂度的重要渠道。

Based on the endogenous technological progress theory, the paper builds a theoretical model to demonstrate that financial development promotes the technological content of a country's exports through spillover effect of foreign direct investment and promoting research efficiency. The paper adopts domestic value - added index to upgrade technical complexity index of export commodities, which mentioned by Hausmann and estimates export complexity of 45 countries in 1995 -2014. The paper empirically examines the channels through which financial development affects the export complexity. The results show that foreign direct investment and R&D efficiency are important channels for financial development to affect the export complexity.
