Five dimensions of energy supply security,economic security,consumption security,environ-mental security and intelligent security were selected to construct China's energy security evaluation index sys-tem.Entropy weight TOPSIS model was used to measure and evaluate China's energy security level from 2005 to 2025,and grey correlation analysis method was used to explore the important factors affecting China's energy security level.The research results show that:from 2005 to 2020,China's energy security level presents a trend of first decreasing and then increasing,and this trend ushered in a turning point in 2019,and energy security is in a"relatively safe"level after the turning point,and there is further room for improvement in 2021-2025.It is proposed that while continuing to promote the clean and green energy transformation,it should also acceler-ate the digital intelligent development of the energy industry and actively promote the construction of a smart energy system.
