Abstract：In-depth analysis of the technological innovation efficiency of the energy industry and the input of innovative resources is conducive to accelerating the energy technology revolution and supporting and guiding the development of new quality productivity in the energy sector.This paper constructs an evaluation index system for the technological innovation efficiency of the energy industry that includes the input of scientific and technological personnel,capital input,and the output of technological achievements.Using the data envelopment analysis method,it measures the technological innovation efficiency and input redundancy of 30 energy listed companies from 2019 to 2023.The research finds that during the measurement period,the number of decision-making units that are completely effective shows an increasing trend,but it is still less than half of the total number.The number of companies with effective pure technical efficiency is greater than that of companies with effective scale efficiency,and the redundancy level of R & D personnel is higher than that of R & D capital input.Based on the measurement results,countermeasures and suggestions for improving the innovation efficiency of energy companies are put forward.
