What is the role of financial development and economic growth on energy consumption in the SADC countries? New evidence from the PARDL approach

This study investigates the interconnections between financial development, economic growth, and energy consumption within the Southern African Development Community (SADC) region between 1980 and 2023. Using the Panel Autoregressive Distributed Lag (PARDL) model alongside Dumitrescu and Hurlin (2012) causality tests, the research provides new insights into the dynamics of these variables. The study reveals a significant positive correlation between financial development, economic growth, and energy consumption. The key finding is the negative relationship between energy consumption and urbanization, while no significant linkage is found between energy consumption and industrialization. The Granger causality test reveals a unidirectional causal link between financial development, urbanization, and energy consumption, and a bidirectional relationship between economic growth and energy consumption. These findings contribute to existing literature by offering a more nuanced understanding of the region’s energy consumption dynamics compared to previous studies that have often presented inconclusive or context-specific results. This study extends previous research by examining the unique economic and energy challenges faced by the SADC countries, providing fresh evidence for policymakers focused on integrating financial sector development with sustainable energy policies. The study suggests that investing in renewable energy and expanding electricity access, especially in rural areas, could enhance both urbanization and financial sector growth, fostering broader economic development. The diagnostic checks affirm the robustness and reliability of the model, ensuring the validity of the findings.
