Abstract: In the worldwide boom of landscape renewal of abandoned railways, the governments of some countries have realized that the interests of different groups need to be coordinated behind the space transformation in order to increase the inclusiveness of the renewal process and results. An effective way to achieve this goal is collaborative planning. According to the attributes of third-party organizations, the collaboration models are divided into three types: expert-based, agency-based, and government-based. Incorporating case studies, this research analyzes the collaboration mechanism and the ways to promote inclusiveness in collaboration. The results show that: 1) The expert-based collaboration model is suitable for downtown areas with diverse types of land use, which is easy to produce spatial diversity; 2) The agency-based collaboration model is suitable for suburban areas with more idle land, which can reserve space for future development along the line; 3) The government-based collaboration model is suitable for areas with mature planning and systematic construction, which is conducive to government control and enables the government to carry out cross-area cooperation. These results are expected to provide experience and theoretical reference for China’s collaborative actions in building an inclusion-oriented renewal of abandoned railways.
