Abstract：Urban infrastructure is commonly known as “main roads, subways, pipeline network, etc.”. In addition, there is a type – back street – often hidden and ignored inside street blocks. A back street generally has commercial service functions. On the one hand, it acts as a public space always, and on the other hand, it is a spatial unit that connects the urban grids and promotes effective circulation of urban resources and factors. This article is based on the empirical research on the back street space of Shenzhen Huaqiangbei. It discusses the historical logic of the transformation of the back street, as well as its spatial logic that supports the flow of “human-object” resources. Finally, it tries to explain the significance of back street as infrastructure in urban blocks, and to clarify the “convergence” of growing urban resources in the back street, which is an important reference for exploring urban redevelopment models.
