Recognition of the nature, foundations and conceptual infrastructures of the plans of external influence are considered as the first strategic steps for a structured confrontation with the malicious plans of the world dominating powers in the field of influence. Regarding such a strategy, this research is aimed at designing a theoretical model for the concept of influence through content analysis and a network of themes within the framework of Imam Khamenei's intellectual system. The main question of the research is: "What are the characteristics of the concept of influence from the viewpoints of Imam Khamenei, and which model can be applied for its analysis?" To answer the question, the researchers tried to identify the outstanding propositions in his statements by referring to elites. Then, the theoretical model of the research was designed by content analysis method. The findings of the research indicated that the conceptual system of influence from the viewpoint of Imam Khamenei encompasses four components including the study of bases, aspects, agencies, and goals, which are significantly related to one other in the framework of his intellectual system.
