Dependency theory is a school of thought primarily used in social science that focuses on the economic development of countries. It argues that the economic status of certain countries as 'developing' or 'underdeveloped' is not just due to their internal characteristics but is a result of their unequal position within the global capitalist economy.
The core argument of dependency theory is that it serves as a critique of modernization theories. Modernization theories generally propose that less developed countries can achieve development by following the path taken by today's developed countries. They suggest a linear progression, often involving industrialization, urbanization, and Westernization.
Dependency theory argues that the global economic structure itself creates and perpetuates underdevelopment, directly opposing the foundational ideas of modernization theories.
