From the analysis of the occupational structure in early modern London, it can be concluded that early modern London consisted of five economically-specialized regions, I.e., the City, based on commerce and finance; the eastern suburbs, based on shipping and shipbuilding; the southern suburbs, based on leisure and service (especially food service); the northern suburbs, based on industry and carriage by land; and the western suburbs, based on conspicuous consumption; also that each region could be regarded as an original early-modern town like those which Prof. P. Corfield classified in her The Impact of English Towns 1700-1800.
