Greener for greater security? The role of green finance in energy security amid rising geopolitical risks
基于37国2013-2018年数据，研究发现绿色金融能显著降低能源安全风险，且在地缘政治风险上升时起到缓冲作用，对高或低风险国家效果更明显。
Energy security is an undeniably crucial factor in economies' stable functioning and societies' well-being. However, global energy security has been continuously threatened by adverse geopolitical events. This study is conducted to examine if green finance can be an effective tool to improve energy security and, if so, whether green finance can act as a shield against geopolitical risk using a sample of 37 countries from 2013 to 2018. Our analysis is also extended to use another proxy of energy security for 36 countries in an extended and updated period from 2013 to 2022. Our results show that green finance can significantly reduce energy security risks worldwide. Furthermore, our heterogeneity analysis shows that the impact of green finance on energy security risks is also more substantial in the OECD (IEA) countries than in non-OECD (non-IEA) countries. Results from the panel quantile regression also show that the impact of green finance is heterogeneous and significant across different quantiles of energy security. This finding suggests a V-shaped pattern from the effect of green finance, indicating that countries with either very high or very low levels of energy security risk benefit the most from green finance. Interestingly, when green finance is considered a moderator in the effect of geopolitical risk on energy security, we find that green finance acts as a shield against the adverse impacts of increasing geopolitical risk. Our results are robust against endogeneity and largely unchanged across different estimations. Important policy implications have emerged from our findings.
