The Belt and Road Initiative (BRI) intends to enhance China's international integration, strikingly by enhancing infrastructure and bolstering trade and investment links among the economies involved. Poor transport infrastructure and border restrictions are significant deterrents to trade expansion, economic growth, and bilateral trade. Using panel structural gravity model estimations, this study investigates the impact of Transportation infrastructure inheritances on bilateral trade across the Belt and Road member countries, particularly in Eastern Africa. The study considers the potential effect of the BRI roads, railways, and Information and Communication Technology (ICT) infrastructure network on the bilateral trade and economies of the Eastern African countries. The empirical analysis offers robust evidence that transport infrastructure promotes trade. The study found that transport infrastructure has a significant and positive effect on trade. These results imply that transport infrastructure exerts a strong effect on trade and growth in Eastern Africa. Policies for increasing access and affordability of transport infrastructure are highly recommended to promote trade and economic growth in the Eastern Africa sub‐region.

The global extent and use of the internet and mobile have increased the importance of mobile financial services (MFS) and payments. However, only limited numbers of review studies are accessible on the topic. Therefore, this paper aims to offer a systematic literature review (SLR) methodology and perform a weight analysis of articles published between 2011 and 2021. By reviewing 61 studies, the results indicate that the unified theory of acceptance and usage of technology (UTAUT) followed by the technology of acceptance model (TAM) are the main conceptual frameworks and models adopted. It reveals that attitude, perceived ease of use, performance expectancy, habit, social norms, and perceived usefulness are the best behavioral intention predictors. The critical technological factors of using MFS were provided, followed by future research opportunities.
