摘要

长期以来，地缘政治风险对全球能源安全和环境可持续性构成重大挑战。本文从超效率SBM模型出发，构建绿色全要素能源效率（GTFEE）指数，考察了1998年至2022年43个国家地缘政治风险对能源效率的影响。采用工具变量分位数回归，结果表明GPR与GTFEE呈正相关，且GTFEE分位数越高，影响越强。这种影响在中低收入水平的发展中经济体中比在高收入发达国家更为明显。此外，采用回归不连续设计，研究发现，军事冲突、国际紧张局势和国际关注的突发公共卫生事件（PHEIC）等事件显著增加了GTFEE。基于世界能源三难困境指数的互补分析进一步表明，地缘政治风险增强了能源安全和环境可持续性。这些发现为政策制定者和实践者提供了优化能源管理战略、增强抵御地缘政治不确定性的能力和促进全球范围内可持续能源实践的实证见解。

Empowering energy security: The impact of geopolitical risks on green total factor energy efficiency

Geopolitical risks (GPR) have long posed significant challenges to global energy security and environmental sustainability. This paper investigates a critical dimension of energy security by constructing a Green Total Factor Energy Efficiency (GTFEE) index, derived from the super-efficiency SBM model, to examine the impact of geopolitical risk on energy efficiency across 43 countries from 1998 to 2022. Employing instrumental variable quantile regression, the results show a positive relationship between GPR and GTFEE, with the effect becoming stronger at higher GTFEE quantiles. This impact is more pronounced in developing economies with mid-to-low income levels than in high-income developed nations. Furthermore, using a regression discontinuity design, the study finds that events such as military conflicts, international tensions, and Public Health Emergencies of International Concern (PHEIC) significantly increase GTFEE. Complementary analysis based on the World Energy Trilemma Index further indicates that geopolitical risks enhance energy security and environmental sustainability. These findings provide policymakers and practitioners with empirical insights to optimize energy management strategies, strengthen resilience against geopolitical uncertainties, and promote sustainable energy practices on a global scale.

期刊介绍： Energy Economics is a field journal that focuses on energy economics and energy finance. It covers various themes including the exploitation, conversion, and use of energy, markets for energy commodities and derivatives, regulation and taxation, forecasting, environment and climate, international trade, development, and monetary policy. The journal welcomes contributions that utilize diverse methods such as experiments, surveys, econometrics, decomposition, simulation models, equilibrium models, optimization models, and analytical models. It publishes a combination of papers employing different methods to explore a wide range of topics. The journal's replication policy encourages the submission of replication studies, wherein researchers reproduce and extend the key results of original studies while explaining any differences. Energy Economics is indexed and abstracted in several databases including Environmental Abstracts, Fuel and Energy Abstracts, Social Sciences Citation Index, GEOBASE, Social & Behavioral Sciences, Journal of Economic Literature, INSPEC, and more.
