撒哈拉以南非洲地区的可持续发展——基础设施对人均财富的影响

Sustainable development in Sub-Saharan Africa:the impact of infrastructure on wealth per capita

一些出色的研究者已经论证了基础设施对实现可持续发展的重要意义。现有文献将财富账户确定为可用于衡量可持续发展的模型。然而,关于非洲基础设施和财富账户的实证研究却很有限。作者试图通过运用财富账户发现撒哈拉以南非洲地区基础设施对可持续发展的影响来填补这个空白,以人均财富作为关注的焦点。研究的面板数据收集自撒哈拉以南非洲地区27个国家,时间段为2003-2016年。作者的主要发现是:基础设施对人均财富具有显著的积极影响。同时,研究也发现,人力资本和自然资本是对当地人均财富具有重要影响的另外两个决定因素。研究没有显示不同的非洲国家群体之间在基础设施对财富的影响方面存在差异。本文提供了令人信服的证据,说明基础设施可以用来促进撒哈拉以南非洲地区的财富创造和促进该地区的可持续发展,因此强烈建议对促进该地区创收的基础设施部门进行投资,特别是交通、能源和信息通信技术基础设施。如果基础设施服务的可利用率得到提升,特别是在被边缘化的地区,就可能提高基础设施在增加人均财富方面的有效性。

Prominent researchers have argued that infrastructure is important for achieving sustainable development.The existing literature has identified the wealth accounts as a model for measuring sustainable development.However,empirical studies relating to infrastructure and wealth accounts in Africa are limited.This study has bridged this gap by using the wealth accounts to find the impact of infrastructure on sustainable development in Sub-Saharan Africa,with a focus on wealth per capita.Panel data was collected from 27 Sub-Saharan African countries over the period 2003-2016.The main finding is that infrastructure has a positive and significant influence on wealth per capita.It was also found that human capital and natural capital are other important determinants of wealth per capita in Sub-Saharan Africa.The findings fail to show any significant differences in infrastructure-wealth impact across African groups.The study provides convincing evidence that infrastructure can be used to promote wealth creation and enhance sustainable development in Sub-Saharan Africa.Investment in infrastructure sectors that promote income generation is highly recommended,especially transport,energy and ICT infrastructure.The effectiveness of infrastructure in increasing wealth per capita can be enhanced if access rates to infrastructure services are increased,especially in marginalised areas.
