This study adopts a comparative approach to analyze successful urban investment practices in countries with advanced urban economies, such as Germany, the Netherlands, South Korea, the United Kingdom, Singapore, and Japan. Drawing on these case studies, the research aims to present a localized policy framework for the Municipality of Tehran. <span style="font-size: 12.0pt; line-height: 115%; font-family: 'Calibri','sans-serif'; mso-ascii-theme-font: minor-latin; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-hansi-theme-font: minor-latin; mso-bidi-font-family: Arial; mso-bidi-theme-font: minor-bidi; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">Amid rapid urbanization (urban population rising from 35% in 1950 to over 55% in 2015 and projected to reach 66% by 2050), many cities face severe fiscal constraints. Although Tehran’s municipal revenues grew from 84,617 billion rials in 2011 to 2,056,589 billion rials in 2025, the share of financing through investment has remained marginal—averaging just 1.2% over fourteen years, with a peak of only 3% in 2012. This underscores the need for more effective investment strategies. The study identifies four key components of successful urban investment: (1) institutional and legal frameworks, (2) innovative financial instruments, (3) stakeholder collaboration, and (4) data-driven governance. Based on these pillars, it proposes the "Smart Investable City Model" for Tehran. This model aims to increase investment-based financing, enhance financial self-reliance, and promote participatory, transparent development.</span> With increasing urbanization and mounting pressure on the financial resources of cities—especially in developing countries—it is vital to develop innovative urban investment models.
