Using ethnographic data gathered in Beijing during 2017 and 2018, this article examines numerous urban population displacement events using the concept of spatial governance in order to understand the spatialization of governance in urban China. A particular focus of this article are the Beijing-wide displacements of the so-called “low-end population” that followed a fire in Xinjian Village in 2017. The analysis in this article uses geographic understandings of spatial informality to interrogate how space is made informal and subsequently illegal as a means of population control. The article puts forward the idea that spatial governance is one of the key forms, if not the key form, of governance in urban China. It highlights changes in governance that have resulted in space becoming not just a site for control, but the medium for techniques of control over China's urban population.
