Amir Kargar Samani *, Asadollah Kordnaeij, Seyed Hamid Khodadad Hosseini, Seyed Masoud Mousavi Shafaee In recent decades, global cities have become important in national, regional and international environments of themselves, because they have great effects on space of flows and have been affected by them. In this regards some scientific and international institutes have ranked the global/world cities and have proposed some comparative tables for them. Local and urban governance, also, are items that play significant roles in contrast with central governments, especially in local management. Urban good governance gives privilege to poor, women progress, civic participation, and interaction with public and private organizations in different social areas and effective management in cities. So, this is one of the especial arguments in city management and is investigated, discussed and developed by various institutes. The importance of these two subjects, have been an incentive to use librarian method with utilizing some reliable city, national and international resources to develop a detailed table for urban good governance of 194 global cities. So relations between urban good governance and city urban situation in some aspects could be assessed. This study indicates that urban good governance in different categories of global cities (especially among the highest category and others) has significant meaningful difference.

The contemporary globalization which is based on Post-Fordist Economy, was formed on the basis of informational capitalism, and has been differentiated from other concepts due to some characteristics like information economy, global economy, and network economic activities.     The characteristics of post-Fordist Economy create a situation where capitals and productions are changed from place-based to spatial flexibility. In these circumstances, cities play the role of spatial support in social network and inside the post-Fordist Economy as new actors of transnational spaces. Metropolises are trying to provide parts of their expenses from the contemporary globalizing situation by using city diplomacy. Today, managements of metropolises are eager to be linked to world cities, not only to earn their management expenses, but also to create job opportunities for their citizens. And, this becomes evident through the city diplomacy. As such, it can be said that new actors of political geography in the 21^st century cities, the, are looking for their financial benefits. The current research deals questions such as: what are the contexts and how cities enter the transnational spaces as new players in the international system? Here, a descriptive - analytical research methodology has been applied. Finally, the paper considers the theory of Peter Taylor, a famous political geographers who theorized globalization, world cities network, the entrance and performance of metropolises in transnational spaces; for instance, new players in the framework of conceptual model.
