IntroductionDependency theory was initially developed in the late 1950s under the leadership of Raul Prebisch, director of the United Nations Economic Commission for Latin America, to explain serious economic problems, such as poverty, economic exploitation and influence in political actions, which occurred in poor Latin American countries due to the development of neighboring developed countries (Ahiakpor 1985; Ferraro 2008). Since it was formulated, dependency theory has become the focus of extensive analysis and debate by both scholars and development practitioners. Although dependency theory has had an important contribution in explaining the situation of poverty and underdevelopment of poor countries (Ferraro 2008), on the contrary, scholars also question the limitations of its approach. This essay has two objectives. First, the meaning of “dependent development” will be revealed, which is considered one of the main approaches to addiction. However, in order to support this aim, the document will also provide a brief definition of addiction at the beginning. Second, two limitations (consisting of the conclusions of two important extensions of the dependency approach) will be discussed in more detail. These are: overemphasis on negative impacts (Frank's conclusion) and oversimplification of internal factors (Cardoso's conclusion). So, we will take Taiwan, one of the dependent countries that has achieved success in economic development, as a case study. Definition of dependency There is no single concept of dependency because it is a continuous process (Ferraro 2008) and dependency theory is a set of ideas formed by many scholars, not just one (Ahiakpor 1985). For example, Sunkel (1969) def... half of the paper ......ncontradicts Cardoso's argument about external factors that can help development, but maintain the relationship of the periphery with the core countries. Conclusion The dependency approach has made important contributions in explaining poverty and associated inequality in poor countries during the development and influence of capitalism and imperialism. The limitations of the dependency approach arise from its oversimplified approach, which overemphasizes negative impacts and external factors while neglecting internal factors, including social, political, and agencies of dependent countries that would help them have potential development opportunities. Due to these limitations, the dependency approach does not seem to keep pace with political and economic development in the era of globalization and this is the reason for the decline of the dependency approach during the mid-1990s. ’80..
