[Purpose/Significance] By calculating the operation efficiency of WeChat public account of academic journals of library, information and archives management, this study understands its development status and gives targeted suggestions. It is of certain guiding significance for the future development of the public account of academic journals of library, information and archives management. [Method/Process] In this paper, 20 journal public accounts were selected as research samples, and the three-stage DEA method was used to determine the input-output index data, the operating efficiency value of each public account was estimated through the DEA-BCC model, and the impact of environmental factors were eliminated combined with SFA regression. [Result/Conclusion] After excluding environmental factors and the influence of random noise, the average comprehensive efficiency of public accounts has increased compared with the first stage, but there are still 16 public accounts that did not achieve DEA effectiveness. Finally, combining with the principle of data envelope analysis, the public account improvement proposal is put forward from two perspectives of saving investment resources and ensuring the effectiveness of investment.
