The Importance of Geopolitical Codes in the Transnational Role of Metropolises: Emphasis on Iranian Metropolises

According to Castells and Taylor, the world was based on space of places until the early 1970s. In such a context, any international interaction of institutions within the state must be pursued through the government, and the government of each country considers itself responsible for its nation and territory. But today, many theorists of globalization and the global cities network have emphasized in numerous articles that in the context of the post-Fordist global economy, cities are collaborating and competing as nodes of networks and new actors in the international arena. From this perspective, they believe that these are global cities that will replace the nation-state in the future. Political geographers around the world, on the other hand, believe that cities not only will not replace the nation-state, but also the they will find new roles and functions in globalization. This paper based on a historical-analytical approach is surveying space of flows interactions according to the logic of geopolitical codes and tries to clarify and explains Iranian metropolises challenges and opportunities in this context.

This research method descriptive-analysis with the method of data gathering is based upon library studies and the use of books, articles Seeks to investigate the interactions of space of flows based on the logic of geopolitical codes.

This research emphasizes that the geopolitical codes of countries affect the activities of cities of a country at three levels on a transnational scale, and the cities of each country according to the geopolitical codes of the same country in these three local, regional and global levels can enter the transnational space and compete and interact with other cities. Iran, with its important features in the arena of world geopolitical rivalries and space of places, has not yet been able to enter into the space of flows and contemporary globalization. For example, with the expansion of the concept of "us" and "the other" as a tool of US politics as a defense mechanism in the global arena, it deals with potential threats in the form of a geopolitical code called the axis of evil.
