Robustness test.

This study investigates the effects of Information and Communication Technology (ICT) goods exports and environmental technology innovation (ETI) on mineral rents using a panel dataset of 23 OECD countries from 2000 to 2020. Employing a fixed-effects regression and several robustness checks (FGLS, PCSE, and DKSE), we find that ICT goods exports are positively associated with mineral rents, while ETI exerts a negative impact. Notably, the positive effect of ICT goods exports was more pronounced in countries with higher levels of ICT goods exports. Our findings underscore the complex interplay among technological advancements, environmental sustainability, and economic outcomes in resource-dependent economies, emphasizing the need for tailored policy interventions to navigate these multifaceted dynamics.
