Beyond disasters: Long-run effect of earthquakes on energy poverty in China

While earthquakes are considered one of the most prevalent natural disasters in China, there is limited empirical evidence regarding the long-term effects of earthquakes on energy poverty. Using data from China Family Panel Studies and China's historical earthquake catalog, this study investigates the long-term effects of earthquake intensity on energy poverty among households in China, and analyzes the long-term effects over different time spans. Our findings indicate that, higher earthquake intensities have an overall worsening long-term impact on energy poverty. When segmented into different time spans, households in regions with higher earthquake intensities are less likely to fall into energy poverty over the past 20 years and the past 20 to 50 years, whereas more likely to be energy poor over the longer time span. Moreover, we uncover that public infrastructure, government assistance, and mental well-being serve as channels through which earthquakes affect household energy poverty, with divergent effects over different time spans. In addition, we observe nonlinear evidence of earthquake intensity's long-term impact on energy poverty, and the long-term impacts are heterogeneous across different regions, as well as households with different registration statuses and household fuel types. These insights can inform policy interventions aimed at alleviating long-term energy poverty in areas affected by natural disasters.
