摘要

自 1958 年以来,相关文献主要讨论的是 "不公平增长 "问题。它描述的是一个国家在国际市场上的出口量相对于进口量较高,从高经济增长中获益,但家庭福利受到损失。本研究旨在调查交通基础设施对解决发展中国家不公平增长问题的贡献,重点是喀麦隆经济,该国在发展道路交通基础设施方面存在严重不足。此外,这项研究还丰富了与 "吝啬增长 "密切相关的更广泛经济影响的讨论。调查发现,福利损失是对实施进口关税和资本所得税这两类财政政策的反应。通过动态可计算一般均衡(CGE)模型,利用外部性方法探讨了道路交通基础设施的影响。这是一种创新方法,最近被用于获取基础设施投资对经济的影响,从而区分生产性和非生产性基础设施投资。研究结果表明,生产性交通基础设施不仅能通过改善家庭福利来减少更广泛的经济影响,还能促进经济增长。由进口关税资助的道路交通基础设施投资每增加 10%,短期和长期的福利改善率分别为 1.94% 和 1.66%,而如果将所产生的财政资金用于纪念碑、国防等非生产性基础设施,则福利损失率分别为 0.58% 和 0.15%。资本所得税资金也有类似的趋势。因此,建议决策者重视道路建设,以缩短公共决策与家庭生活条件之间复杂的相互作用。

Contribution of road transport infrastructure in mitigating the inward–immiserizing growth in Cameroon: An externality approach in computable general equilibrium analysis
The issue of immiserizing growth has been largely discussed in the literature since 1958. It describes a country context contending with high volume of exports relatively to its imports on the international market that benefits from high economic growth but losses in households’ welfare. This study aims to investigate the contribution of transport infrastructure to tackle immiserizing growth in developing countries, focusing on the Cameroon economy, a contending with a significant lack in the development of road transport infrastructure. Further, the study enriches the debate on the wider economic impacts, closely related to immiserizing growth. The loss of welfare is observed upstream to the investigations, as a response to the application of two types of fiscal policies: the import tariff and the capital income tax. Through a dynamic Computable General Equilibrium (CGE) model, the effect of road transport infrastructure is explored, using the externalities approach. This is an innovative methodology recently applied to access the economic impacts of infrastructure investment making a difference between productive and non-productive infrastructure investments. The findings reveal that productive transport infrastructure not only reduces the wider economic impact by improving households’ welfare but also enhances economic growth. A 10 percent increase in road transport infrastructure investment funded by import tariff leads to a welfare improvement of 1.94% and 1.66% in both short and long terms compared to respective losses of 0.58% and 0.15% if the generated financial funds are allocated in non-productive infrastructure such as monuments, defense etc. The similar tendency is observed for the capital income tax funding. Thus, policymakers are recommended to accentuate the road construction, in order to shorten the complex interplay between public decisions and households’ living conditions.

期刊介绍: Sustainable Futures: is a journal focused on the intersection of sustainability, environment and technology from various disciplines in social sciences, and their larger implications for corporation, government, education institutions, regions and society both at present and in the future. It provides an advanced platform for studies related to sustainability and sustainable development in society, economics, environment, and culture. The scope of the journal is broad and encourages interdisciplinary research, as well as welcoming theoretical and practical research from all methodological approaches.
