This study initiated from the problem regognition that NHIC which is the only social insurer is need to improve its efficiency in an era of environment change such as increase of national health expenditure according to population aging and sustainability of NHI and the methodological limit of advanced researches. This study intended to figure out the cause of the inefficiency of NHIC by analysing static efficiecy through DEA and efficiency trend through DEA/Window analysis. Reseach data is collected from the internal data of NHIC Health Insurance Policy Rsearch Institute Finance and Statistics Center, National Health Insurance Statistical Annual Report and National Medical Examination Statistical Annual Report and applied to the research analysis. According to the results, most NHIC brances are need to improve Scale Efficiency (SE) and RTS (Return to Scale) analysis showed the same results. We think that this is because SE has been gradually deteriorated because internal resources of NHIC is backed up and could not follow the change of performace. This means that managerial efficiency such as human resources and administrative cost is need to be improved.
