In recent years, the number of areas with declining populations has been increasing due to the declining birthrate and aging population in regional cities across the country. Especially urban decline is accelerating due to population concentration in the metropolitan area and the stagnation of local industries. In order to prevent such urban decay, the law SPECIAL ACT ON PROMOTION OF AND SUPPORT FOR URBAN REGENERATION was enacted in 2013, and urban regeneration projects are being promoted in local cities across the country. However, after the implementation of the urban regeneration project, the side effects of infrastructure maintenance and planning-oriented projects have begun to be discussed, and the limitations of small-scale life-oriented urban regeneration projects through urban regeneration policies are appearing. In order to solve this, it is necessary to develop a private- participation urban regeneration model that can generate continuous profits by strengthening the local self-sustaining capabilities. In particular, in order to actively induce private companies to participate in urban regeneration projects, it is necessary to establish the role of the public sector in urban regeneration and at the same time expand the public-private partnership(PPP) relationship to attract private investment. This study aims to provide basic data for promoting urban regeneration projects and to promote the revitalization of private-private urban regeneration projects through public-private partnerships(PPP) through case studies of public-private partnerships(PPP) operation with a focus on overseas cases of urban regeneration.
