Abstract
Aims: By 1404, Tehran will be a knowledge-based, smart, and global city. Having the proper infrastructure and consequently a metropolis with national and global functions with a modern economy are its other features. The global experience of metropolises management shows that optimal urban management requires comprehensive attention to the city's economic, social, and environmental structures, and this has been measured in recent decades, globally, by the urban competitiveness index. Therefore, the present study was conducted with the aim of evaluating the urban competitiveness and Tehran’s status among the metropolises of Iran.
Instruments and Methods: The present study is an applied and survey research that was conducted in 2011. Eleven variables were selected as economic indices of urban competitiveness such as unemployment rate, economic participation rate, etc., by the library method and from three official sources of the country: statistical yearbooks of the provinces, results of census of industrial workshops with 10 employees and more, published by the Statistical Center of Iran and statistics of Ministry of Cooperatives, Labor, and Social Welfare. Standardized score and numerical taxonomy were used.
Findings: Tehran metropolis ranked first in terms of urban competitiveness index and economic aspect. Tehran was the first metropolis of Iran with a score of 3.13 in terms of the urban competitiveness index in standardized score method and 0.72 in numerical taxonomy.
Conclusion: Although Tehran does not have a good status in terms of the urban competitiveness index compared to other metropolises in the world, it ranked first in this index among Iranian metropolises.

Abstract
Introduction: Considering the settlement of more than 60% of the world's population in cities by 2030, producing over 70% of the world's carbon there, and 50% of the damage to the ozone layer by cities, as well as less experience in organizing environmental issues in cities, studying the successful experience of countries, especially global metropolises in planning environmental issues may be essential. Accordingly, this research is theoretical in terms of nature, applied in terms of conclusion, and descriptive-analytical and documentary in terms of method. The data were collected and analyzed from library resources, field observations from some metropolises, and Internet resources related to the world capitals and global metropolises perspective (15 items).
Conclusion: At least since 2000, in all the perspectives for the studied capitals and metropolises, urban environmental issues have been one of their main goals and basic themes. The land of "no burial" and "no waste" is the motto of most of them. The completion of the cycle of reduction of consumption, recycling, and reuse is considered the main objective of sustainable development. The integrated urban environmental management model was emphasized; flexibility and effective strategic resilience are considered to reach the UN's 2030s sustainable development goals. Therefore, it is proposed that the 17-item UN's 2030s sustainable development goal, particularly item 11 that is related to urban sustainable development, as well as the United Nations environment program, be the basis for urban sustainable environmental programs, especially in Iranian metropolises.

Abstract
Abstract Terrorism and terrorist attacks is one of the biggest challenges in the 21st century. Each year, thousands of people around the world lose their lives due to terrorist attacks. Cities and metropolises are one of the foremost spaces to organize and carry out terrorist attacks. In fact, today the vast majority of terrorist attacks are happening in big cities so that terrorism can be considered a primarily urban phenomenon. Iran and its big cities are exposed to terrorist attacks due to the characteristics of the regional and the existence of terrorist groups in conflict with the Islamic Republic of Iran. There are a number of potentially vulnerable sites against terrorist attacks in Shiraz metropolis such as vital infrastructure, public places and centers of political power. In this paper have been used analytical descriptive method and documentary and inductive approach. In this paper, we first examine the locations of terrorist attacks in large cities in the world, and then have been analyzed the most important locations at risk of terrorist attacks (conventional and non-conventional) in nine municipality zones of Shiraz. The results of this study show that zones 1, 2 and 8 in Shiraz are most important and vulnerable zones against terrorist attacks, due to physical characteristics, population concentration and multiplicity of infrastructures.

Abstract
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 21st 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.

Abstract
Introduction
Extensive and efficient infrastructure is critical for ensuring the effective functioning of the economy. Investing in public infrastructure represents an essential investment in economic development and standard of living of city residents. Therefore, it is necessary to find new methods of financing in providing services and developing urban infrastructure in metropolises and increasing the welfare of urban society. However, the current approach to revenue mobilization for cities is unlikely to meet the substantial financing needs. Instead, there is a need for a metropolitan public financing strategy that is integrated into national urban development plans and matches national development objectives. In the literature related to city finance, despite the importance of providing suitable urban infrastructures, the discussion about how to fund them, especially in Iran, is rarely done. Therefore, the purpose of this research is to provide a suitable model for providing financial sources for public infrastructure in metropolitan cities with an emphasis on Isfahan metropolis.
Methodology
In this research, a mathematical model for calculating the urbanization tax has been introduced, in which the cost recovery coefficients are related to the optimal size of the cities. Therefore, an equilibrium model is constructed based on cost-benefit analyses and applied to nine Iranian cities with population more than one million people. The panel data regression analysis was performed on a fourteen-year period (2006-2020) using the Transcendental Logarithmic (Translog) function. The obtained results are placed in the basic mathematical model. It should be noted that Excel2016 and Stata12 software were used to estimate the model and analyze the results.
Findings
The results of estimating the regression models related to determining the optimal size of the cities indicate that all the metropolises have exceeded their optimal size. Among the nine metropolitan cities studied, Kermanshah, Karaj and Qom have the largest excess population. Isfahan and Ahvaz have the lowest excess population. The results of calculating the urbanization tax for Isfahan Municipality indicate that the recovery of public infrastructure depreciation costs in the first year can generate more income than the income from property tax for Isfahan metropolis.
Discussion and Conclusion
Providing infrastructure and public services by municipalities for the urban population, especially in metropolises, is a very difficult task and requires access to capital facilities. However, the way to collect these funds and how to provide the infrastructure budget has been less attention. In order to provide public services and urban infrastructure, municipalities should collect the costs related to a certain infrastructure as much as possible from the individuals, companies, localities and groups that benefit from it.
Therefore, in this study, all the urban infrastructures of Isfahan metropolis are divided into three categories based on the benefits they create. The first category is infrastructures whose benefits are assigned to certain individuals and groups. The second category is infrastructures whose benefits are mostly limited to one place or a specific area within the city. The last category also includes those services and infrastructures whose benefits are allocated to the entire city and its residents.
The results show that about 38% of infrastructure costs in Isfahan metropolis are related to the third category. Considering the allocation of these infrastructures to all residents, their cost can be collected through the urbanization tax and according to the optimal size of the cities. The results related to the city size model show that the population of all Iranian metropolises has exceeded its optimal size, so it is suggested to continue receiving infrastructure costs until full recovery.
The results of this research emphasize that although the urban costs have decreased with the increase in population, the urban benefits have decreased more, and in general, diseconomies of scale have been created. However, people will not necessarily involve these diseconomies of scale that they bring to the city in their decisions related to work and migration. Therefore, it is recommended to receive these costs from them.

Abstract
The examination of the official metropolitan regions of Iran elucidates their pivotal function in the configuration of the spatial frameworks of provinces. These regions serve as economic and social nuclei, shaping the allocation of resources and fostering development. Comprehending this function is instrumental in developmental strategizing and mitigating regional disparities. This research investigates the influence of metropolitan regions on the spatial configurations of provinces through the analysis of demographic concentration, regional activities, and urban hierarchies. Quantitative techniques, including the Ttest, Kmeans clustering, and Moran's I index, are utilized in this scholarly inquiry. The results suggest that the eight provinces possessing established official metropolitan centers exhibit a higher level of advancement compared to the 23 provinces that do not have such centers. Furthermore, the adjacent provinces surrounding these metropolitan regions also demonstrate a greater degree of development. The outcomes derived from the Moran's I index illustrate a clustered spatial arrangement, which is corroborated by the Inverse Distance Weighting (IDW) map, thereby underscoring the concentration of development in the central plateau of Iran. Nevertheless, the province of Khorasan Razavi deviates from this pattern due to its geographical proximity to less developed regions. The application of Kmeans clustering has identified Tehran, Isfahan, Fars, and Alborz as the most developed provinces, while Qom and Sistan and Baluchestan are categorized within the less developed cluster. These results underscore the critical importance of metropolitan areas in facilitating the structural transformations occurring within Iran's provinces.
