Measuring the rate of development and the degree of globalization of cities with emphasis on the thought of John Friedman

Despite extensive efforts to determine criteria for identifying and distinguishing these cities, so far no single theoretical and empirical basis for identifying global cities has been provided. One of the basic and important ways to understand the characteristics of global cities and the extent to which cities are moving towards development and globalization are the descriptions and characteristics provided by various researchers. This basic research is a descriptive-analytical method of expressing and examining the theories presented by the eminent researcher John Friedman, about the characteristics of global cities and how to reach a global city. Friedman believes that the three world cities of London, New York and Tokyo, with their large economies in hand, have taken over the role of commander and the top of the urban hierarchy. The importance of this research lies in the fact that by emphasizing the ideas of John Friedman, it shows the ways to achieve development and progress, and according to the outstanding criteria of the world city, it paves the way to the world city.Based on the research results, it can be said that the city should show its dynamic characteristics. Any metropolis that can be influential at the international or global level in one of the fields of economics, culture and politics, and as a center and a superior pole, can assume functions such as international command, domination and control in its geopolitical space, can Have the status of a world city.
