Scientific diplomacy, as an emerging instrument in urban governance, has the potential to enhance the position of global cities within the knowledge-based international system. Focusing on Tehran and employing a comparative analysis of four metropolitan cases—Barcelona, Boston, Beijing, and Istanbul—this article seeks to answer the following question: How can urban policymaking, through scientific networking, knowledge-based branding, and the engagement of universities and innovative enterprises, contribute to improving urban management patterns and strengthening the international standing of a city such as Tehran?
The findings, derived from a comparative methodology, indicate that each city has pursued a distinct model of urban scientific diplomacy: Barcelona through its “innovative ecosystem initiative,” Boston through “university-driven innovation,” Beijing through “state-developmental scientific diplomacy,” and Istanbul through “cultural-identity advantage building.” The comparative analysis reveals that despite Tehran’s significant potential—stemming from its universities, research institutes, and technology ecosystem—it lacks a strategic document for urban scientific diplomacy, a stakeholder coordination mechanism, and a coherent scientific branding structure. The article concludes by proposing an integrated strategic model for Tehran, built upon four pillars: networked governance, university-centered diplomacy, scientific-cultural branding, and alignment with national science, technology, and cultural policies. This model can facilitate Tehran’s transition toward becoming a knowledge-based city with active participation in regional and global scientific networks.

Extended Abstract
Introduction
In the emerging knowledge-based global order, cities have become significant actors capable of shaping transnational scientific interactions, innovation networks, and cultural-knowledge exchanges. Urban diplomacy is increasingly intertwined with scientific and technological capabilities, enabling cities to develop distinctive global identities and attract flows of talent, investment, innovation, and collaborative research. Within this context, scientific diplomacy has evolved into a strategic instrument for strengthening the international visibility of cities, expanding their innovation ecosystems, and contributing to national soft power. This study examines the role of scientific diplomacy in urban governance through a comparative assessment of four global cities (Barcelona, Boston, Beijing, and Istanbul) and proposes a strategic model for Tehran.
Purpose
The purpose of this study is to analyze how leading cities use scientific diplomacy as a tool of urban governance, to identify the strengths and gaps in Tehran’s current approach, and to offer a strategic framework that can assist Tehran in transitioning toward a knowledge-based and internationally engaged metropolis.
Methodology
The research employs a qualitative and comparative methodology. First, a thematic review of the scientific diplomacy practices of Barcelona, Boston, Beijing, and Istanbul is conducted, focusing on governance mechanisms, institutional actors, frameworks of scientific collaboration, and policies for city branding. Second, these findings are compared with the current situation in Tehran using dimensions such as innovation infrastructure, stakeholder coordination, international presence, and cultural-knowledge positioning. Data were drawn from policy analyses, institutional reports, and qualitative insights derived from the structure and discourse of the urban innovation and diplomacy landscape.
Findings
The comparative analysis identifies four distinct models of scientific diplomacy in global cities:
1.     Barcelona, the Creative Ecosystem Model: Barcelona leverages its culture of design, creativity, and urban innovation to build research networks, foster technology districts, and cultivate an international scientific brand rooted in openness and collaboration.
2.     Boston, the University-Centered Innovation Model: Boston’s scientific diplomacy is deeply connected to world-class academic institutions such as MIT and Harvard. These universities anchor global collaborations, attract top talent, foster high-tech entrepreneurship, and form the backbone of the region’s international scientific presence.
3.     Beijing, the State-Driven Science Diplomacy Model: Beijing utilizes a state-led developmental approach that aligns urban scientific diplomacy with national science and technology strategies. Through large-scale investments, scientific megaprojects, and strong government coordination, the city has rapidly built global research networks.
4.     Istanbul, the Culture–Science Hybrid Model: Istanbul promotes a culturally grounded identity combined with expanding academic networks and regional connectivity. Its scientific diplomacy blends cultural heritage with emerging innovation initiatives.
When comparing these cases with Tehran, several significant strengths and gaps emerge:
v Strengths: Tehran hosts leading universities, research centers, a rapidly expanding technology ecosystem, and strong cultural assets. It possesses human capital and scientific capacity that could support an active urban scientific diplomacy strategy.
v Gaps: Most notably, Tehran lacks an integrated strategic document for urban scientific diplomacy, suffers from fragmented governance across scientific and municipal institutions, and does not possess a coherent international scientific branding strategy.
Existing capacities are dispersed and insufficiently connected to global networks.
Coordination between academia, industry, and city governance remains limited.
Practical Implications
The findings suggest that Tehran requires a multi-level governance strategy that integrates science, technology, culture, and urban development. Practical steps include:
v Establishing a dedicated scientific diplomacy office within Tehran’s municipal governance structure;
v Developing international partnerships with universities and innovation districts in leading cities;
v Enhancing branding initiatives to position Tehran as a city of science, heritage, and innovation;
v Strengthening collaboration among universities, research institutes, technology parks, cultural organizations, and the municipal government.
Social Implications
A robust scientific diplomacy strategy can foster social innovation, enhance public engagement with science, improve the city’s talent retention, and encourage a more inclusive knowledge society. It can also facilitate cultural-scientific linkages that promote mutual understanding and global dialogue.
Originality
This study provides one of the first comprehensive frameworks for conceptualizing scientific diplomacy within the context of Iranian urban governance. By combining comparative global insights with Tehran’s specific opportunities and challenges, the paper offers an innovative hybrid model tailored to the sociocultural, technological, and institutional realities of Tehran. The strategic model proposed here contributes to broader debates on the emerging role of cities as scientific actors in the global system.
