Research on Functional Interdependence Patterns of "village-Urban" Spatial Structure of Shenzhen: A Living and Activity Space Perspective

The urban village is a special product of the rapid urbanization process in China. To accurately understand its functional embedding mode in the urban organism is an important decision-making prerequisite for optimizing the governance effectiveness of urban renewal. Taking residents' living and activity space as the breakthrough point, this paper analyzes the spatial functional patterns of villages in cities by measuring the "village-urban"interdependence relationship based on cellphone big data. It is founded that urban villages in Shenzhen are closely related to other parts of the city, and are not self-isolated communities. At the same time, due to the extensive construction and management mode, the function homogenization of urban village space is obvious, and its location is the main determinant of its participating way in urban activities. The research holds that from the perspective of providing citizens with low-cost opportunity to participate in urban public life and ensuring the resilient development capacity, it is necessary to coordinate and reserve a certain proportion of urban village residential land within the sub-community of residents' living and activity space to promote the benign and healthy development of urban space organisms.
