Abstract：Security input-output benefit of power supply enterprise is a complicated system with multiple input and output .It is necessary to analyze the efficiency of the security input-output to develop improve-ment measures to improve the security investment management level .Seven input indexes and two output indexes are selected on the basis of the definition of power supply enterprise ’ s security investment and se-curity benefit.Then, a model of power supply enterprise’s security input and output is established based on data envelopment analysis (DEA).The model is applied to a case study and found that some of the power supply enterprises have low efficiency in security input-output and they need to optimize the use of security investment .The result shows that the DEA method can evaluate the efficiency of security input -output for power supply enterprise and find the insufficiency in optimizing safety input costs .
