Theories and models
At their simplest, the basic theories on regional development can be portrayed as a left-wing versus a right-wing view of development. The right-wing view (also termed “liberal” or “orthodox”) is that regional inequalities arise through the operation of normal economic forces in the course of capitalist development, and disappear also through the working out of these same economic forces. Leftwing views (also “radical”, “structuralist”) also have regional inequalities as coming about through the operation of capitalism, but interpret these differences as being instrumental to the maintenance of capitalism, and actively promoted by capitalist agents, whether firms, individuals or governments. Because of their importance, the inequalities between regions are maintained by capitalist powers and do not disappear through a process of convergence.
