ENVIRONMENT DEVELOPMENT AND SUSTAINABILITY, 2025 (SCI-Expanded, Scopus)
Emerging economies rich in natural resources face a persistent challenge in balancing rapid economic growth with long-term environmental sustainability and social equity. This study aims to empirically examine how digitalization, resource management efficiency, and economic diversification influence sustainable development across resource-abundant developing countries. Using panel data from 1996 to 2022 for a selection of emerging economies, the analysis applies the Method of Moments Quantile Regression (MMQR) model alongside FMOLS and DOLS estimators to uncover heterogeneous effects across different levels of sustainable development. The results reveal that digital infrastructure significantly enhances sustainable development, with stronger impacts observed in higher quantiles of sustainability performance. Resource management efficiency consistently exhibits a positive and statistically significant influence across all quantiles, confirming its foundational role in reducing environmental pressure and optimizing resource use. Clean energy adoption, while modest in magnitude, also demonstrates a positive contribution, particularly at mid-to-upper quantiles. Rural development is found to exert one of the most substantial impacts, suggesting that inclusive spatial planning is key to driving sustainability outcomes. Although economic diversification shows a generally positive association, its effect is more muted and less robust across quantiles, indicating that structural transformation processes may require time and targeted support to yield significant sustainability dividends. These findings underscore the importance of integrating digital, environmental, and economic reforms to design resilient and inclusive sustainability policies in emerging economies.
