Abstract

Nowadays, Metropolitan ‎regions, as powerful economic, political, and social centers of gravity, as well as the dominant urbanization pattern, particularly in developing countries, play an important role in regional, national, and even global economic growth and development. Therefore, it is essential to recognize this concept and enrich studies on this field. Hence, the extant study aims to carry out a meta-analysis on scientific-research papers that have focused on Metropolitan ‎regions over the last decade and a half in Iran. According to the findings, studies on this field have decreased since 2015, and the nature of studies, in terms of the distribution of research fields, implies the priority of physical-spatial studies(49%), followed by Managemental (19%), and economic (16%) studies. The analysis of the findings on the nature of studies indicate that these studies are consistent with the prevailing global trend and the changes in these studies stem from variation in the quiddity of these regions, and alteration in the dominant research paradigm (from macro to meta-macro notions). The content of the reviewed research indicate that studies on livability, quality of life, and sustainable development have been insufficiently considered. On the other hand, there has been a content gap in the key areas of spatial structure and regional development. The Why questions in this field have been mainly examined superficially, and the investigation of How questions has been just limited to solutions recommended at the end of papers or the use of some models for anticipations. Investigating the theoretical dimension of studies indicates the shifts in theoretical approaches, especially in physical-spatial and economic studies, also the weakness of theoretical foundations, particularly in environmental and socio-demographic studies. Regarding the methodological dimension, most studies have been done using quantitative techniques, and fewer studies have used qualitative and mixed methods. The results showed that the nature of the majority of Metropolitan ‎regions in Iran based on inequalities and spatial imbalance. Moreover, the extant study strives to suggest some solutions based on the meta-analysis of studies as follows, the necessity of having a approach,eliminate spatial segregation from plannings, use of the neo-regionalism approach to promoting management system’ efficiency in these regions, the necessity of transition from the hierarchy approach to the development of small cities and activity sub-centers to provide spatial balance, and strengthening polycentrism to create a policymaking framework in these regions.
