Environmental sustainability, small and medium enterprises, and finance in Africa: a triplicate relationship

The age-long debate between SME-growth nexus has ignored environmental sustainability, as evident by many previous empirical studies. However, the pivotal role of SMEs and their undeniable dominance in the business landscape of Africa presents itself as a potential instrument for leading sustainability advocacy on the African continent. The study investigates whether credit flows from the private sector and government-owned enterprises to small and medium enterprises guarantee growth and environmental sustainability using data from World Bank Databases for 35 African countries from 2006 to 2019. Results from the econometric analysis show that domestic credit flowing from the private sector and government-owned enterprises to SMEs leads to significant growth with greater impact at lower quantiles in the case of Africa. On the issue of environmental sanctity, credit flowing from the private sector to SMEs counteract the adverse effect of SMEs activities on the environment, while credit flowing from government enterprises intensify the negative effect of SMEs activities on the environment in the case of Africa. Furthermore, renewable energy significantly reduces environmental decay more efficiently in upper quantiles while natural resource rents aggravate environmental decay only for African countries in the lower quantiles. Policy recommendations are proffered in the manuscript within the ambit of the study findings.
