Spatial spillover effects of natural hazards on energy technology innovation-empirical evidence from provincial panel data.

Energy technology innovation is the necessary way and fundamental means to lead, promote, and support the revolution of energy production and consumption. While natural hazards, as an unavoidable external risk in the long-term development of human society, may affect the regional energy innovation level. In this study, we use the SDM bifixed model to investigate the direct, indirect, and aggregate effects of natural hazards on energy technology innovation for data of 31 provinces in China from 2011 to 2020. Results indicate that (1) Natural hazards not only have a significant negative impact on local energy technology innovation, but also inhibit energy technology innovation in neighboring regions, with significant spatial spillover effects. (2) Natural hazards have a more pronounced effect in western cities. (3) Natural hazards can enhance energy technology innovation through increasing environmental regulation and reducing FDI. Our study offers suggestions for strengthening post-natural disaster reconstruction and sub-regional resilience to disaster shocks, improving environmental regulation laws and regulations, and attracting more foreign direct investment.
