Integration theories: A review of selected political and economic concepts

There are a number of integration theories based on different knowledge domains. Whatever their conceptual and analytical focus are, all these theories aim to find and provide a reliable explanation based on intelligent, perceivable, and reliable evidence of integration. Most concepts in social sciences do not have the commonality of understanding and can even be context- or culture-specific. As a result, there is no one universal perception of integration. Hence, the aim of the article is to revisit and systemize the knowledge of integration theories. in political and economic terms. The research methods applied in the article include literature review and comparable analysis. The article is structured into three parts. First, the political theories of integration are elaborated upon. Second, the economic integration theories are examined, focusing on the traditional and new economic integration theories, to proceed finally to the presentation of the economic integration theory for developing countries.
