"World-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and periphery countries.[4] Core countries have higher-skill, capital-intensive industries, and the rest of the world has low-skill, labor-intensive industries and extraction of raw materials.[5] This constantly reinforces the dominance of the core countries.[5] This structure is unified by the division of labour. It is a world-economy rooted in a capitalist economy.[6] For a time, certain countries have become the world hegemon; during the last few centuries, as the world-system has extended geographically and intensified economically, this status has passed from the Netherlands, to the United Kingdom and (most recently) to the United States.[5]
Immanuel Wallerstein is the main proponent of world systems theory.[7] Components of the world-systems analysis are longue durée by Fernand Braudel, "development of underdevelopment" by Andre Gunder Frank, and the single-society assumption.[8]Longue durée is the concept of the gradual change through the day-to-day activities by which social systems are continually reproduced.[8] "Development of underdevelopment" describes the economic processes in the periphery as the opposite of the development in the core. Poorer countries are impoverished to enable a few countries to get richer.[8] Lastly, the single-society assumption opposes the multiple-society assumption and includes looking at the world as a whole.[8]
