Abstract

Exports from high-income countries are three times more diversified than those from low-income economies. We provide a new tech-based interpretation of the stages of diversification accompanying the economic growth paths of countries. Using the decomposition properties of the relative Theil index in a sample of 160 countries (1996–2018), we reveal that export diversification is driven mainly by changes in the variety of non-tech exports. However, the role of the technological component (technological diversification) increases as countries grow, and in high-income countries, it is responsible for more than one-third of the overall export diversification level. We examine country-specific diversification trajectories, showing that the rapid development of technological capacity drove export diversification in China or India. The technological component can explain 40 % of the perfectly diversified U.S. export structure. We show that 4IR exports embodying digital technologies play a negligible role in the diversification process due to their small measurable share in total exports.
出口多元化的技术含量——经济增长过程中的演变
高收入国家出口的多样化程度是低收入国家出口的三倍。我们对伴随各国经济增长路径的多样化阶段提供了一种新的基于技术的解释。利用1996-2018年160个国家的相对泰尔指数的分解特性,我们发现出口多样化主要是由非技术出口种类的变化驱动的。然而,技术组成部分(技术多样化)的作用随着国家的增长而增加,在高收入国家,它占总出口多样化水平的三分之一以上。我们研究了具体国家的多样化轨迹,表明技术能力的快速发展推动了中国或印度的出口多样化。技术成分可以解释40%的完全多样化的美国出口结构。我们发现,体现数字技术的第四次工业革命出口在多元化过程中发挥的作用可以忽略不计,因为它们在出口总额中所占的可衡量份额很小。
