Abstract：New quality productivity is of great strategic significance for the realization of high-quality development in China.By focusing on the power industry,an important industry of low-carbon transformation,we selected 2021-2023 data of representative A-share listed power companies to analyze the development efficiency of new quality productivity.The input-output factors conforming to the logic of productivity evaluation are constructed,and the DEA-Malmquist efficiency index model is used to analyze the efficiency of DMU.It is found that the variance of the development efficiency of the new quality productivity of the listed electric power companies is large,with gradient distribution and location effect.The production technology of each enterprise can meet the daily production and operation needs and basically does not appear the production process mismatch problem,the pure technical efficiency of the head company is higher,but the return to scale effect is difficult to break through significantly,but there is less waste of production resources.Based on this,relevant suggestions are put forward from the aspects of regional collaboration,technological progress and innovation input.
