The operation of electric power industry is closely linked to the smooth development of society, so the study on the using efficiency of power resources is significant. Based on the study sample, the data from 2011 to 2018, this paper analyzes the annual using efficiency of power resources based on DEA model, obtains the slack variable values of input and output, calculates the projection values of invalid variables and gets that the amount of power resources used in power industry is relatively higher. This theory avoids the research on the cost problem of each investment, and completely transforms multi-input and multi-production into fractional problem, so that applying DEA to measure using efficiency can combine input with production, and evaluation indicators finally obtained are more comprehensive and representative. It can be observed from the analysis results that the using efficiency of electrical energy also significantly affects the using efficiency of power resources, so improving the using methods and making all resources allocated relatively optimal can maximize the output, in order to make the using efficiency of power resources reach the maximum value.
