摘要

本研究以撒哈拉以南非洲国家的出口贸易为重点,考察了数字技术与贸易绩效之间的关系。主要目标是考察以信息通信技术商品进口、互联网使用和移动电话订阅衡量的数字技术对撒哈拉以南非洲(SSA)出口贸易的影响,评估该地区发展程度和出口贸易之间的联系,以及最适合促进该地区贸易的数字技术形式。研究假设:(1)ICT产品进口、互联网使用和移动电话用户对SSA出口贸易的影响不显著;(2)区域发展与区域内出口贸易关系不明显;(3)任何形式的数字技术都不能促进该地区的贸易。考虑到面板最小二乘、固定效应和随机效应估计技术,采用面板回归估计技术。结果表明,与互联网使用相比,信息和通信技术进口对出口贸易流动产生了更大的积极和显著的影响,这表明技术在贸易流动中的理论和实践相关性。发展程度较低,对该地区的贸易流动没有明显影响,这表明贸易一体化在结构良好的经济体中可以更好地发展。冗余固定效应检验证实面板最小二乘估计优于固定效应估计。Hausman检验表明随机效应估计也优于固定效应估计。为了实现数字化进程对SSA的贡献,政策制定者需要追求能够解决阻碍其成功的问题的主要目标。

Digital Technology and Trade Performance in Sub-Saharan Africa
This study examines the relationship between digital technology and trade performance with a focus on export trade in sub-Saharan African countries. The main objectives are to examine the impact digital technology measured by ICT goods import, internet use and mobile telephone subscriptions have on export trade in Sub-Saharan Africa (SSA), to evaluate the link between the degree of the region’s development and export trade and the form of digital technology most suitable in facilitating trade in the region. The study hypotheses are that: (1) ICT goods import, internet use and mobile telephone subscriptions do not influence significantly export trade in SSA; (2) the region’s development does not link appreciably to export trade in SSA; (3) no form of digital technology can facilitate trade in the region. The panel regression estimation technique is adopted considering the panel least squares, fixed effect and random effect estimation techniques. Results show that information and communication technology imports exert greater positive and significant impact on export trade flows compared to internet usage demonstrating theoretical and practical relevance of technology in trade flows. The degree of development is low and does not show an appreciable impact on trade flows in the region indicating that trade integration can thrive better in a well-structured economy. Redundant fixed effect test confirms that the panel least squares estimation is better compared to the fixed effect estimation. Hausman test demonstrates that random effect estimation is also better than fixed effect estimation. In attaining the reality of the contribution of digitalization process in SSA, policy makers need to pursue major goals that would address problems hampering its success.
