Abstract

PurposeInfrastructure deficiency and supply disruption challenges are quite common among developing economies. While Sub-Saharan Africa is not unique to these challenges, it is the extent of levels of infrastructure deficiency and disruptions that affect the level of performance of small businesses. Literature on the performance of small businesses suggests both infrastructure availability and disruptions affect the performance of small businesses, but the effects on informal enterprises that operate from locations where the supply of infrastructure is weak are less documented. The paper, therefore, investigates the effects of four types of infrastructure supply in two dimensions of availability and disruption levels on the performance of informal enterprises in 12 Sub-Saharan African countries.Design/methodology/approachThe study uses data from World Bank informal enterprises surveys based on a sample of 3 735 informal enterprises. The study uses the multiple analysis of variance method based on the World Bank's Informal Enterprise Surveys (IFS) country-level cross-sectional data collected between 2009 and 2019.FindingsResults show infrastructure supply is quite low irrespective of the form of infrastructure. Infrastructure availability is associated with high supply disruptions. Infrastructure supply deficiency and disruption intensities are negatively associated with informal enterprises' performance. Finally, the effects of both infrastructure availability and supply disruptions are positively associated with informal enterprises' business activity levels.Research limitations/implicationsDue to data limitations, only four types of infrastructure are captured in the analysis. A wider variety of types of infrastructure could improve the analysis.Originality/valueGiven the deficiency level of infrastructure and its implications on informal enterprise development, therefore, policy interventions aiming at addressing informal enterprises' challenges should focus on improving infrastructure supply deficiencies and disruption challenges. This paper provides the link between infrastructure levels, infrastructure supply disruptions and performance of the informal enterprises which is an essential starting point for policy intervention in informal enterprise development.

基础设施可用性和中断程度对企业绩效的影响:对撒哈拉以南非洲非正规企业的调查
目的基础设施不足和供应中断挑战在发展中经济体中很常见。虽然撒哈拉以南非洲并非这些挑战所独有,但影响小企业业绩水平的是基础设施不足和中断的程度。关于小企业业绩的文献表明,基础设施的可用性和中断都会影响小企业的业绩,但对在基础设施供应薄弱的地方运营的非正规企业的影响却很少有文献记载。因此,本文从可用性和中断水平两个维度调查了四种类型的基础设施供应对12个撒哈拉以南非洲国家非正规企业绩效的影响。设计/方法/方法本研究使用了世界银行非正规企业调查的数据,该调查以3 735家非正规企业为样本。该研究使用了基于2009年至2019年期间收集的世界银行非正规企业调查(IFS)国家层面横断面数据的多元方差分析方法。调查结果显示,无论基础设施的形式如何,基础设施供应都相当低。基础设施的可用性与高供应中断有关。基础设施供应不足和中断强度与非正规企业的绩效呈负相关。最后,基础设施可用性和供应中断的影响与非正规企业的商业活动水平呈正相关。研究限制/含义由于数据限制,分析中只捕获了四种类型的基础设施。更广泛的基础设施类型可以改进分析。独创性/价值鉴于基础设施的不足程度及其对非正规企业发展的影响,因此,旨在应对非正规企业挑战的政策干预措施应侧重于改善基础设施供应不足和中断挑战。本文提供了基础设施水平、基础设施供应中断和非正规企业绩效之间的联系,这是政策干预非正规企业发展的重要起点。
