Abstract:

Urban functional space renewal is an important means of revitalizing urban spaces, regenerating human memory, and reshaping spatial vitality in the new era; it is the core engine of sustainable urban development. In this paper, first, based on the development history of western urban renewal, we defined the concept and connotation of urban function renewal, and then systematically reviewed the research on urban function renewal at home and abroad; we focused particularly on the background and succession trajectory, function renewal models and spatial organization, research paradigm and space judgment, and driving mechanisms and planning regulation. Importantly, we discovered that the urban function renewal trend is closely related to the economic and social development level and the urbanization stage. Moreover, the urban functional renewal operation mode was observed to reflect the tendency of diversified cooperation between the governments, private sector, and communities. Additionally, the urban functional renewal judgment showed the tendency of multi-source data fusion and identification, and the urban functional renewal strategy was shown to be affected by multiple factors, such as policy control, the driving economic force, and market mechanisms. Particularly, with respect to the transformation and adjustment of the urban development in China in the new era, research on urban function renewal focuses more on the scientific cognition of urban renewal practice, the refined turn of spatial governance capabilities, and the humanistic return of governance concepts. Importantly, this paper focused on some hot topics of the urban function space research and has presented an in-depth discussion and analysis of issues, including the construction of the theoretical system and practical framework of urban function renewal in the new era; the succession characteristics of functional business research, and the regulation of localized policy were also addressed. Of note, existing research studies mainly qualitatively describe and analyze the update mode of a single function type at the macro-scale of cities and regions; reports on multi-temporal cognition and objective evaluation of business succession under the microscopic view are still insufficient. For this reason, we proposed that the renewal of urban functions in China should, in the future, pay more attention to the micro-spatial scale, especially the multi-dimensional quantitative analysis of the renewal mode of fine urban functions. Additionally, the integration of systematic research ideas should be considered for the generation of comprehensive methods to condense a universal, representative, and complete theoretical system of urban function renewal.
