Impact of digital divide on energy poverty across the globe: The mediating role of income inequality

Energy poverty is an important reality facing the whole world, and the rapid development of digital technology has great potential in eradicating poverty. However, the differences in the level of information development have led to the existence of the digital divide within countries. In this context, this paper explores whether and how the digital divide affects energy poverty from a global perspective. Based on cross-country panel data, this study focuses on the effect and asymmetry of the digital divide on energy poverty. The results show that the digital divide hinders the reduction of energy poverty and manifests itself in a Matthew effect that makes the energy poor poorer. Second, the heterogeneity analysis based on income level and rural-urban areas find that the digital divide has a greater negative impact on energy poverty in low-income countries and rural areas. Finally, the mechanism analysis reveals that the digital divide exacerbates energy poverty mainly by increasing income inequality. Therefore, there is a greater need to focus on the efficiency, equity and inclusive development of the digital economy in the process of its globalization. The findings can also provide an empirical basis for policy design to bridge the digital divide and alleviate energy poverty.
