After World War I, many wealthy Americans started decentralizing out of the cities and into the suburbs. During the second half of the 20th century, department stores followed the trend of moving into the suburbs. In 1968, Kain formulated the “Spatial Mismatch Hypothesis”, but he did not refer to it by this term. His hypothesis was that black workers reside in segregated zones that are distant and poorly connected to major centers of growth. The phenomenon has many implications for inner-city residents dependent on low-level entry jobs. For example, distance from work centers can lead to increasing unemployment rates and further dampen poverty outcomes for the region at large. Since its conceptualization in the late 1960s, the spatial mismatch hypothesis has been widely cited to explain the economic problems encountered by inner-city minorities.4
In 2007, Laurent Gobillon, Harris Selod, and Yves Zenou suggested that there are seven different factors that support the spatial mismatch phenomenon.5 Four factors are attributed to potential workers accessibility and initiatives. The remaining three factors stress employers' reluctance to divert away from the negative stigma of city people and in particular minorities when hiring.
Growth of ghost cities in China, mostly from not yet agglomerated areas between or adjacent metropolitan areas or coal mining towns, as in the case of the most famous example, Kangbashi New Area of Ordos, are an example of spatial mismatch. In the case of places near metropolitan areas, it represents less of a risk going forward than in mining areas.
