ABSTRACT
The industrial revolution, which was in fact a prolonged evolution, unleashed a set of forces that vastly changed traditional societies. Economies became diversified, populations migrated to the cities, new classes and political alignments appeared, and standards of living rose. The term postindustrial was coined rather casually in the late 1950s in an analysis of work and leisure. The postindustrial society builds on the gains furnished by the earlier industrial revolution: high levels of production, national income per capita, savings, and investment. In older models, the modern society was assumed to be a highly industrialized and integrated unit. Contemporary models of development pick up certain constructs from the older models. Japan's economy suffered from a dual structure, however, marked by the coexistence of traditional and modern elements. Japan's growth in the 1960s and early 1970s was immeasurably aided by the dual structure of the economy.
