Answer:
World-systems theory (also known as world-systems analysis or the world-systems perspective)[1] is a multidisciplinary approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis.[1] "World-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and the periphery countries.[2] Core countries focus on higher skill, capital-intensive production, and the rest of the world focuses on low-skill, labor-intensive production and extraction of raw materials.[3] This constantly reinforces the dominance of the core countries.[3] Nonetheless, the system has dynamic characteristics, in part as a result of revolutions in transport technology, and individual states can gain or lose their core (semi-periphery, periphery) status over time.[3] This structure is unified by the division of labour. It is a world-economy rooted in a capitalist economy.[4] For a time, certain countries 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.[3]A world map of countries by their supposed trading status in 2000, using the world system differentiation into core countries (blue), semi-periphery countries (purple) and periphery countries (red). Based on the list in Dunn, Kawana, Brewer.
World-systems theory has been examined by many political theorists and sociologists to explain the reasons for the rise and fall of states, income inequality, social unrest, and imperialism.
