In this study, we conducted an investigation on administrators designated by local authorities for managing and maintaining public parks in the country to find the implementation system, their types of revenue sources and their use of revenue. Then, we identified challenges in creating park management and designated administration operation systems which enable administrators to offer high-quality maintenance and management with their business know-how, and lastly showed the direction for dealing with the challenges. The study revealed that the fact that their own revenue must be allocated to the expenses for managing and maintaining the park without enough the expenses only for the usage fees and designated administration fees is a big problem related to the foundation of the systems. The study also found important challenges that the re-investment should be evaluated in the annual evaluation of the administrators' performance based on the situation that designated administrators of more than half have re-invested in the park maintenance. The study also found that, to obtain their own revenue sources, deepening the cooperation by utilizing the advantages of each, such as the advantage of getting revenue from businesses in profit organizations and the advantage of receiving contributions in non-profit organizations, is the effective direction.
