GIS AND URBAN STUDIES: POSITIVISM,POST-POSITIVISM,AND BEYOND

An information theoretic model is used to compare the evolution of the spatial distribution of corporate headquarters in the United States during the period 1957- 1979 with an ideal time-space model. Dispersion of headquarters across the regions of the U.S. has been the dominant trend for most subsectors of the economy since the mid-1960s. Corporate concentration has been a compensatory trend that has left the overall system dispersion of headquarter location at a stable and unchanging level for the country as a whole.
