Analysis and Ranking of Tehran Metropolitan Sustainability Among Global Cities

In the era of globalization of economy, metropolises play an important role in countries development, especially in developing countries.Today, metropolises by entering into the global cities network have access to the world-wide capital markets, advanced technologies, tourism and trade and thereby the background of economic and social dynamic is provided. The Aim of this research is to prove this theory that the planning and efforts of urban managers particularly metropolises for connecting to the global cities network was a step in the development of cities. Due to the benefits of this network, including the flow of foreign capitals, production technologies and facilitating the exchange and export of manufactured and produced goods in to the world markets, major parts of the present problems and challenges can be solved. In this regard, this research has considered the relationship between the rank of the global city and the rate of their stability. In order to study this relationship, the results of Taylor and his colleagues study about determining and ranking the global cities have been used. Firstly 16 cities among the world cities of the both groups of developing countries and developed countries as well as Tehran metropolis was selected and then the status of economical, social, environmental and physical indicators of these cities were extracted and was ranked using TOPSIS model. At the final stage the rank of their sustainability was compared with the rank of their global city. The results show that the cities with high ranking and position among in the ranking of global cities equally have higher stability. Meanwhile Tehran metropolis also had the least privilege and evidence of globalization in the rankings of Taylor, has the less rank of stability. Also, the results of correlation test between globalization variable and sustainability is a positive significant coefficient 0.54 which implies a positive and significant relation between globalization of city and urban sustainable development.
