Editor’s Note: During the rapid urbanization of China in the past 30 years, the development of new urban areas and new cities and the renovation of old cities are two key factors. Generally speaking, the urban renewal in China mainly refers to the redevelopment of the industrial areas and the renovation of the residential quarters in the built-up areas of a city. As an important part of the comprehensive strategy of urban regeneration, it concerns not only the renewal of physical environment, in particular the adjustment of land-use and the rehabilitation of old buildings, but also the upgrading of economic structure, the restructuring of social organization, the identification of urban culture, etc. Due to its complexity, the practice of urban renewal in Chinese cities has brought about a series of problems in the past decades, such as the beneficial conflicts among various stakeholders, the gentrification of actual residents, and the fading of traditional identity, etc., in the over development of real estate. Thus great efforts have also been made in various localities to deal with these problems from different aspects and in accordance with the actual situation of each locality, such as the practice of Shenzhen, Wuhan, Xiamen and Nanjing, which are mentioned in this issue. It is hoped that diversified modes of urban renewal would be worked out through the numerous local practice, which could be an indispensible part of the characteristics of the urban development of contemporary China.
