| Summary: | Drawing upon the existing literature and practice, the study revealed two main ways to renew urban villages, namely demolition and reconstruction and on-site rectification. However, it is challenging to meet the sustainable development needs of the city regarding economy, society, and environment using these approaches. Accordingly, they have become the key factors restricting the process and effect of urban renewal. Therefore, this study introduces the theory of sustainability science, draws lessons from the three-dimensional analysis framework of "object-subject-process" in management science, and establishes the research framework of sustainable renewal mode in urban villages by taking communities and individual projects as the spatial scale of research. This model emphasizes several dimensions. The object dimension entails pursuing economic and social prosperity under the premise that the key natural capital is not reduced. The process dimension consists of conducting the whole process reform of the causal chain. The main dimension encompasses pursuing the cooperative governance of the government, enterprises, villagers, and village collective. The empirical study of Huanghe Village in Hou Lake, Changsha, was planned by the government, contracted by enterprises, and coordinated by village communities through house preparation. In addition, this paper evaluates the renewal path of "moving but not demolishing and overall development and comprehensive renovation" from the perspective of sustainable development. The results show that the model has a positive impact on balancing the interests of multiple parties, revitalization of the stock of land resources, promotion of the upgrading of industrial structure, improvement of the urban space quality, and protection of the village culture. However, since the model does not involve the changes of the property rights of farmers' self-built houses, it is difficult to fundamentally solve the historical problems originating from the process of urban village renewal, such as the transformation of farmers' citizenship status and farmers' livelihood risks. In addition, the case selected by the empirical study is specific in terms of the location and evolution process, which may directly affect the copy effect of the case. Nevertheless, this study is an attempt to interpret the practice of urban renewal using the theory of sustainability science, which provides new insight into promoting the sustainable renewal of urban villages, as well as experiences in China.
