The research method of this thesis is Archival Analysis method. First of all, according to accreditation of the hospital, we selected 104 hospitals, 73 hospitals organization charts in total, for the research objects. Secondly, we categorized organization charts based on the ownership of hospital and its statues. Finally, we deduced the types of hospitals administration department from their history and hospital administration management developed history. According to the result, there are three types of hospitals administration department that include: the Model of National Taiwan University Hospital, the Model of Chang Gung Memorial Hospital, and the Model of China Medical University Hospital. Most of Taiwan hospitals are belonged to the Model of National Taiwan University Hospital and the Model of Chang Gung Memorial Hospital. These two types existed before the National Health Insurance practiced. However, the Model of China Medical University Hospital occurred and developed into a staff system after the National Health Insurance practiced. By the configuration theory of Henry Mintzberg, the National Taiwan University Hospital Model is a professional organization, and its administration department is acting as assistance in managing, the medical unit leads the control over all. On contrast with the National Taiwan University Hospital Model, The Chang Gung Memorial Hospital Model tended to be a machine organization, administration is a core management which had a powerful authority. The China Medical University Hospital Model is a combination of those two models but slightly tends to machine organization; therefore its administration department has the authority. By understanding the role of management and it¡¦s important in hospital system, administrator has to rethink about the mission statement, the prospect and the impact from the changing of hospital system based on macro viewpoint in order to manage its Human Resource Management resources efficiently.
