However the research of this area have been mainly focused on the analysis of financial health based on the size or selectivity of universities and professionalization of staff or cooperation between staff and faculty and the approach from the organizational point of view remains unexplored field. This paper examines the university management and organization focusing on private universities. Three areas-governance, personnel system and organizational climate are focused on as the organizational characteristics and the relationship between university organization and adequacy of the student quotas of enrollment is examined. University governance such as strength of autonomy of faculty and president of board of trustees from a founding family or not and organizational climate such as sharing of goals have some important effect on the financial health of universities on the one hand, but personnel system has no clear influence while it improves work motivation of staff.
