Metropolitan-hinterland thesis
The metropolitan-hinterland thesis (or centre-periphery thesis) theory of social and economic development, developed by the Canadian historian Harold Innis examines how economically advanced societies, through trade and colonialism, distort and impede economic development of less developed societies and regions. A metropolis is identified as the centre of political and economic power.
