In his attempt to modify the limitation of the Perroux growth model, R.P. Mishra developed a hybrid theory (model) combining the concept of Christaller’s CPT, Friedman's concept of Core-Periphery, and Hagerstrand’s Spatial Diffusion Model. My concern is which country (region or locality) in the world successfully implemented this theory (or a variant of it) to operationalize the needs of the people of the predominantly rural countries such as Ethiopia or India (rural people)? How was it made functional? Had there been related policy instruments? Had there been programs or projects? Any pertinent document to support such operationalization?
