| description | A well-functioning economic infrastructure is fundamental for sustainable
economic growth in both developing and developed countries. It can be an effective tool for
addressing economic and socioeconomic challenges and improving a country’s
competitiveness. It is therefore critical to understand how economic infrastructure
investment affects different aspects of economic growth. This would assist policymakers in
ensuring that there is proper alignment between policies on infrastructure development and
policies pertaining to economic development. Although many studies have been conducted
on the impact of infrastructure development on economic development, literature focusing
on the foreign trade aspect is scant. This study, therefore, bridges this gap by examining the
impact of economic infrastructure investment on foreign trade flows in South Africa in the
long run and short run. To examine this linkage, the study applied the autoregressive
distributed lag (ARDL) bounds test on annual data for the period 1986 - 2022 and estimated
two models. Model 1 investigates whether economic infrastructure investment has a
significant impact on exports, while Model 2 examines the impact of economic infrastructure
investment on imports. The findings of the study confirmed that economic infrastructure
investment has a positive impact on exports both in the long run and short run, while it has
no significant impact on imports. On the control variable, the findings confirmed that
economic growth only has a long-run positive impact on exports, while it has a long-run and
short-run positive impact on imports. It was found that trade openness and real effective
exchange rates have positive effects on foreign trade flows regardless of the proxy used.
The results confirmed that human capital has a negative effect on exports in the long run
and short run, while it only has a positive long-run impact on imports. Furthermore, the
findings show that money supply does not affect exports, while it negatively drives imports
both in the long run and short run. Based on the main findings, the study recommends that
governments should design policies that support investment in improving the country’s
geographical conditions and connectivity. Furthermore, it is recommended that the South
African government should prioritize the establishment and maintenance of functional
economic infrastructure to create a conducive environment for local productivity and exports. |
