This study examined the effects of both aggregate and disaggregated infrastructural development indices (such as transport, electricity, ICT, and water and sanitation infrastructure indices) on economic performance in Africa. The study used the dynamic system GMM framework and found that both aggregate and disaggregated infrastructural development indices impact positively on GDP per capita growth in Africa. These impacts were shown to be significant in all cases, except for the transportation infrastructure index. The results overwhelmingly confirmed the prevalence of the symmetric hypothesis in the infrastructure–growth relationship in Africa. The study also found some evidence in support of the significant roles of capital, labour and initial GDP per capita in Africa’s economic performance, while the role of trade remained negative and muted. The study concluded that through effective public administration, African leaders and policymakers can promote economic performance on the continent by evolving policies that favour increased infrastructural development, human capital development and capital accumulation.

非洲的公共基础设施发展和经济表现:来自面板数据分析的新证据

本研究考察了综合和分解的基础设施发展指数(如交通、电力、信息通信技术以及水和卫生基础设施指数)对非洲经济表现的影响。该研究使用动态系统 GMM 框架,发现总体和分解的基础设施发展指数对非洲的人均 GDP 增长都有积极影响。这些影响在所有情况下都显示为显着,除了交通基础设施指数。结果压倒性地证实了对称假设在非洲基础设施-增长关系中的盛行。该研究还发现了一些证据,支持资本、劳动力和人均初始 GDP 在非洲经济表现中的重要作用,而贸易的作用仍然是消极和微弱的。
