Abstract：Against the background of intensifying global geopolitical conflicts,the issue of energy security has once again become the focus of attention of the international community.The article systematically analyzes the evolution of energy security categories at home and abroad,and reveals their common development patterns and different characteristics.It is found that the evolution of energy security at home and abroad shows the common development law of transitioning from single energy supply guarantee to multi-dimensional dynamic coupling.Early foreign energy security research focused on the stability of energy supply,and then gradually expanded to the analytical framework covering the coupling of the 3E(energy,economy and environment)systems,which profoundly revealed the intrinsic correlation and mutual influence among the three.In the 21st century,the 3E synergistic perspective has become a new paradigm for addressing the challenges of energy transition and climate change.On the basis of international advanced theories,domestic energy security research has built a unique research system with Chinese characteristics based on local conditions.The research path has shifted from emphasizing energy self-sufficiency to diversified and globalized cooperation strategies,and under the dual driving force of the "One Belt,One Road" Initiative and the "dual-carbon" goal,the research center of gravity has gradually shifted to the field of sustainable energy security,focusing on improving energy efficiency and optimizing the energy structure,It focuses on strategies to improve energy efficiency,optimize energy structure and strengthen international cooperation,aiming to promote the transformation of the energy system into a cleaner and lower-carbon one,and to achieve the harmonization of economic,environmental and social benefits.
