Which theory proposed by Immanuel Wallerstein links social change in developing countries to economic activities of developed countries?

World Systems Theory, proposed by Immanuel Wallerstein, provides a comprehensive framework for understanding the interconnectedness of global economies and social systems. This theory posits that the world is divided into a core, semi-periphery, and periphery, where developed countries (the core) exploit the resources and labor of developing nations (the periphery).

Wallerstein's theory highlights how economic activities, such as trade, production, and investment patterns established by core countries, have significant implications for social change in peripheral nations. These interactions often perpetuate inequality and dependency, shaping the developmental pathways of countries based on their position within the global system. This perspective emphasizes that changes in developing countries cannot be understood in isolation but must be viewed as part of a larger economic and social structure influenced by the actions and policies of more developed countries.

While the other theories also address aspects of development and social change, they do not focus specifically on the global economic relationships as a primary driver, as Wallerstein's theory does.
