摘要

背景:多年来,南非政府一直强调改善城市的社会经济基础设施,因为这是促进基层发展的重要催化剂。尽管地铁的交通基础设施投资大幅增加,但所有这些交通投资集中的地铁的贡献似乎很少利用它来促进基层发展。目的:本研究调查了公共交通对南非产出增长的影响。方法:采用单向误差成分面板分析法,对2003 - 2017年全国8个主要地铁的分类数据进行分析。数据主要来源于公共交通支出、社会基础设施支出总额、资本形成总额、劳动力支出和产出增长率。结果:研究结果与以前对南非交通支出和增长的研究结果明显不同。在人口最多的地铁中,有6个地铁显示了结果,这表明公共交通支出对其产出没有显著影响;但当与其他社会基础设施结合在一起时,它表现出显著的影响。然而,其余两个小地铁的结果表明,公共交通支出及其与其他社会基础设施的结合都对其产出增长产生了显著影响。结论:交通基础设施投资符合资本边际产量递减理论。六大地铁应该加大对社会基础设施的投资,以补充当代交通基础设施的投资。另一方面,仍有必要增加小型地铁的公共交通基础设施投资。

An analysis of the impact of investment in public transport on economic growth of metropolitan cities in South Africa
Background: Over the years, the South African government has emphasised improving the metros’ socioeconomic infrastructures because these form an essential catalyst that can boost grassroots development. Despite the considerable increase in investments in transport infrastructure in the metros, the contributions of the metros where all these transport investments are concentrated appear to be making little use of it to promote their grassroots development. Objectives: The study investigated the impact of public transportation on the output growth of South Africa. Method: One-way error component panel analysis is adopted to analyse disaggregated data from eight major metros in the country from 2003 to 2017. Data were mainly sourced on public transport expenditure, total social infrastructure expenditure, total capital formation, labour expenditure and output growth rate from each of the metros. Results: The results were a clear departure from what was obtained by previous studies on transport expenditure and the growth of South Africa. Six of the metros which are the big ones in terms of the population showed a result, which indicated that public transport expenditure did not influence their output significantly; but when combined with other social infrastructure, it exhibited significant impact. However, the results of the remaining two small metros showed that public transport expenditure and its combination with other social infrastructure all had a significant impact on their output growth. Conclusion: This confirms transport infrastructure investment conforms to the theory of the diminishing marginal product of capital. The six big metros should invest more in social infrastructure, which would complement the contemporary transport infrastructure investment. On the other hand, there is still a need to increase public transport infrastructure investments on the smaller metros.
