Global Governance in the Urban Age: Urban Development Strategies from an OECD Perspective

Cities: Emerging Actors in Global Governance

For a long time, cities have been regarded as subordinate units below the state in the international political and economic landscape—implementers of policies, consumers of resources, and epicenters of problems. However, as the global population continues to concentrate in cities, and as issues such as climate change, digital transformation, and social inequality converge intensely in urban spaces, cities have quietly become a core prism for understanding changes in global governance. The fact that the Organisation for Economic Co-operation and Development (OECD) has made urban development an important policy area itself reflects an underestimated structural shift in the international order: cities are shifting from the endpoints of national governance to the starting points of global strategy.

From the Margins to the Center: Why Cities Have Become Strategic Focal Points

The urban development issues that the OECD focuses on are not simple urban planning or infrastructure management, but rather systemic challenges covering climate adaptation, digital governance, inclusive growth, fiscal decentralization, and regional competitiveness. Behind this agenda-setting lies a profound recognition of the repositioning of cities' roles.

Over the past half century, the global economic landscape has undergone dramatic restructuring. The global relocation of manufacturing, the explosive growth of the service industry, and the rise of innovation clusters have made cities key hubs for the flow of production factors. At the same time, cities are also major sources of carbon emissions, primary victims of extreme weather, and visible arenas of social stratification. When national governments feel inadequate in the face of these cross-cutting challenges, cities naturally become the frontline for policy experimentation and institutional innovation.

The OECD's "green countries, regions and cities" framework deserves particular attention. It places cities at the core of climate action, recognizing that local action plays an irreplaceable role in achieving net-zero emissions targets. This perspective breaks the traditional one-way logic of "national governments set targets, local governments execute orders," and instead emphasizes collaboration and experimentation among different levels of government. Cities are no longer passive responders but active shapers of climate governance.

Infrastructure, Investment, and Urban Power Structures

The rise of cities' strategic status is also reflected in infrastructure investment and the redistribution of fiscal power. Under its finance and investment agenda, the OECD has specifically established a section on "subnational finance and investment," attempting to address a key question: as cities take on more responsibilities for public services and infrastructure, does their fiscal autonomy match these responsibilities?

This is not merely a technical fiscal management issue, but also an adjustment of power structures. If cities lack stable revenue sources and investment capacity, they will find it difficult to address long-term challenges such as population growth, housing pressure, and public transportation. The OECD's research and recommendations in this field are essentially promoting a new urban contract—granting cities greater governance space in exchange for more effective provision of public goods.In the Global South, the urgency of this issue is even more pronounced. Rapid urbanization coexists with infrastructure gaps, and many cities, lacking adequate fiscal resources, still need to accommodate millions of new residents. The OECD has identified "urbanization, infrastructure and development" as an important theme of development cooperation, reflecting the international community's re-examination of urban infrastructure investment and financing mechanisms. This is no longer just about building roads and bridges, but about how to construct a spatial order that is resilient and equitable amidst the wave of urbanization.

Digital Transformation and the Next Chapter of Urban Governance

Emerging technologies are rewriting the underlying logic of urban governance. The OECD's attention to issues such as artificial intelligence, digital government, and data governance is deeply intertwined with urban development topics. Smart cities, digital twins, AI-assisted decision-making—these concepts are moving from science fiction to everyday practice. However, the introduction of technology is not value-neutral.

While urban digitalization improves efficiency, it may also widen the digital divide, erode privacy, and entrench algorithmic bias. The OECD's policy frameworks on AI governance and digital security provide cities with a prudent ethics for technology application. As the level of government closest to citizens, cities are inevitably becoming the primary arena for the implementation of digital governance. When sensors line the streets and algorithms participate in resource allocation, cities are in effect becoming testing grounds for public power in the technological age.

This makes urban governance far more complex than ever before. There remains a huge institutional vacuum between traditional municipal management logic and the emerging logic of digital governance. The policy dialogue and standard-setting promoted by the OECD are precisely attempts to fill this vacuum—enabling cities to embrace the benefits of technology without sacrificing inclusiveness and accountability.

Regions, Cities, and the Nation: A New Collaborative Relationship

Within the framework of "regional, rural and urban development," the OECD emphasizes the connectivity between different spatial scales. Urban development cannot be separated from its hinterland, and regional balance cannot be achieved by suppressing urban agglomeration. This perspective enters into dialogue with the current global anxiety over the "urban-rural gap."

In many countries, cities and rural areas are depicted as opposing poles: cities are symbols of prosperity and opportunity, while rural areas are synonymous with neglect and decline. But the OECD's analytical tradition tends to reveal the complementary relationship between the two—cities serve surrounding areas through market connections, while rural areas provide cities with ecological resources and living space. The real policy challenge is not to make all places the same, but to establish a governance mechanism that can unleash the potential of different spaces.

This way of thinking actually represents an upgrade of traditional national regional policy. The state no longer attempts to measure all places by a single standard, but rather recognizes that cities, towns, and rural areas at different levels have different functional roles. The rise of city clusters, the construction of inter-city transport networks, and the formation of subnational economic belts are reshaping the economic geography within countries. The OECD's continued monitoring and research on this process provides an important reference for understanding spatial restructuring in the post-industrial era.

Strategic Turn in the Urban Age

When we place the OECD's agenda in urban development within a broader historical context, a clear trend emerges: cities are becoming indispensable actors in the global governance system. Whether in climate action, digital transformation, infrastructure financing, or social inclusion, cities are no longer merely "delivery mechanisms" for national policies, but rather "generative spaces" for policy innovation.

For policymakers, international organizations, and investment institutions, this means that the cognitive framework for understanding cities must be fundamentally updated. Cities are not objects to be managed, but partners to be empowered. Although the OECD's urban development work focuses primarily on data analysis, policy recommendations, and standard-setting, its deeper significance lies in advancing a shift in the center of gravity of governance philosophy: from state-centric vertical governance to multi-level collaborative networks that include cities.

The true meaning of the urban age is not merely the demographic fact that the majority of people live in cities, but rather that our collective fate—economic prosperity, climate security, social justice—will increasingly depend on how cities are governed, how they are invested in, and how they are imagined. In this sense, urban development is no longer a sectoral policy issue but a core narrative concerning the future of global governance. The OECD's placement of urban development in a prominent position on its work agenda is precisely a growing confirmation of this narrative. In the years ahead, a yardstick for measuring whether international organizations have truly adapted to the changes of our times will be whether they are willing to move cities from the policy backdrop to the strategic forefront.
