The identity crisis of preventive medicine appears to have been deepening. As a solution, it is insisted that preventive medicine should focus on clinical preventive medicine. However, in the field of heath policy and management, the better solution should be found in a serious search for visions and perspectives of its study on population and society. In this regard, the specialist who studies the field can be defined as a medical doctor majoring in public health. In this paper, I first forecasted major socioeconomic changes to occur in medical and public health arena and explored the role of those studying health policy and management. Secondly, I summarized their career paths and main activities in order to establish visions. Finally, I proposed curriculums on health policy and management for medical school undergraduates and for specialists majoring in preventive medicine, respectively.
