The rapid increase of global cities in the 1990s would count now to reach more than 100 cities. Many of these global cities are trying to influence the global economy by differentiated or similar advanced instruments. The capacities and the details of these instruments have not been scientifically investigated in detail, despite the delicate role of the global cities makers and their capacity to influence the socio-economies as powerful economic actors. These intermediary economic actors are very influential in the making and un-making global cities. The “Global City Makers” economic actors and practices in the world city network by Hoyler et. al. (2018) is been reviewed from this perspective mainly. As this book help to identify the influence of certain economic planning on the socio-economic fate of millions of peoples today. Engaging critically and constructively with global urban studies from a relational economic geography perspective, the book outlines a renewed agenda for global cities research.
