本文调查了撒哈拉以南非洲地区电信基础设施的影响。我们使用世界发展指标数据库，并将工具变量广义矩方法应用于 1993 年至 2012 年期间 47 个国家的小组。结果表明，互联网和移动电话对经济增长做出了贡献。互联网和手机使用量每增加 1 个百分点，增长率将分别提高 0.12 和 0.03 个百分点。总体而言，结果表明电信基础设施的发展促进了撒哈拉以南非洲地区的经济增长。由于电信基础设施的潜在增长空间很大，非洲各国政府应大力鼓励扩大接入或降低成本的政策，特别是在互联网方面。
This paper investigates the impact of telecommunications infrastructure in Sub-Saharan Africa. We use the World Development Indicators database and apply the instrumental variable-generalized method of moments to a panel of 47 countries over the period 1993-2012. The results show that the Internet and mobile phones have contributed to economic growth. A one percentage point increase in Internet and mobile phone usage raises growth by 0.12 and 0.03 percentage points, respectively. Overall, the results suggest that the development of telecommunications infrastructure fosters economic growth in Sub-Saharan Africa. With much room for potential growth enhancement of telecommunications infrastructure, policies to expand access or reduce cost should be strongly encouraged by African governments, particularly as far as the Internet is concerned.
