This paper introduces a new exploratory space-time analysis tool for describing processes of spatial redistribution of a given variable. This method, called spMorph, combines spatial clustering techniques with inequality measures to determine endogenously the two components of a spatial redistribution process: (a) the shock, which is the moment that triggers a spatial redistribution process; for example, a new policy, a war, an earthquake, etc.;and (ii) the duration of the regime fade, which is the time between the shock and the moment inwhich a new regime emerges as a better representation of the spatial distribution of the attribute.Two examples are provided: the first uses China’s provincial per capita GDP between 1978 and2008, and the second uses state level housing price and unemployment rate data for the USbetween 2002 and 2012.
