Introduction: New Variables in Capital Flows
Over the past decade, the direction of global foreign direct investment (FDI) has undergone profound changes. Traditionally, capital chased low-cost labor and resource endowments, but today, institutional quality, financing ecosystems, and regional agglomeration capacity have become more durable competitive factors. Against this backdrop, development finance—especially national development finance institutions (DFIs)—is shifting from a marginal tool into a core catalyst for regional economic clusters.
Saudi Arabia’s practice offers a case of significant research value for this transformation. Through the National Development Fund (NDF), the country coordinates 12 specialized funds and banks to channel capital precisely into areas with comparative advantages, in a manner resembling a “quasi-industrial policy.” From the coffee industry in the southwestern province of Jazan to the green hydrogen project in NEOM, development finance is reshaping the country’s internal industrial geography and redefining its position in global supply chains.
The Logic of Agglomeration Economies and the Financing Gap
Alfred Marshall was the first to propose the concept of “agglomeration economies”: when identical or related economic activities concentrate in a specific geographic space, production efficiency improves through knowledge spillovers, labor sharing, and networks of intermediate inputs. To this day, this theory remains a cornerstone of regional competitiveness research.
However, the formation of agglomerations does not occur automatically. Emerging industrial clusters in particular often face financing constraints: early-stage projects are high-risk, have limited collateral assets, and involve uncertain technological paths, making traditional commercial banks reluctant to engage. At this point, development financial institutions become key players in addressing “market failures.” They not only provide patient capital and concessional financing, but also attract private capital to follow through signaling effects, generating a “public leverage” effect.
The World Economic Forum’s “Industrial Cluster Transformation” initiative shows that 40 clusters globally contribute approximately $508 billion in GDP and have created or sustained 4.6 million jobs. Behind these figures, without exception, lies the imprint of synergy between policy finance and private capital.
Saudi Arabia’s Institutional Design: Coordination Rather than Fragmentation
What distinguishes Saudi Arabia’s National Development Fund is its systematic coordination capacity. The NDF’s 12 funds and banks each perform their own functions: the Agricultural Development Fund, the Industrial Development Fund, the Small and Medium Enterprise Bank, the Export-Import Bank... Together, they cover the entire financing chain from startup to globalization. This matrix-style architecture avoids the pain point of institutions operating in silos under traditional government support, enabling the rapid mobilization of multidimensional resources around a regional cluster.Take the Jazan coffee industry as an example. In 2024, the Agricultural Development Fund approved 49.1 million riyals (about $13.09 million) for the production, processing, and marketing of coffee beans, an increase of 54% year-on-year. This growth was no accident; it was the result of a deliberate increase in investment after identifying regional comparative advantages at the national level. Jazan Province, located in the southwest, has a microclimate suited to high-quality coffee cultivation and a traditional agricultural base. With the intervention of financing, the region now has more than 2,500 coffee farms and 400,000 coffee trees, producing over 800 tons of coffee beans annually, with plans to expand the tree stock to 1.2 million by 2026.
From Resource Endowments to Global Exports: The Growth Path of Clusters
This case vividly demonstrates how development finance transforms "dormant resources" into "active assets." First, financing lowers the threshold for farmers and small and medium-sized enterprises to enter the industrial chain; second, through targeted support for processing and marketing, local value is retained within the region; third, improved product quality gives Saudi coffee the potential to enter the global specialty coffee market, thereby expanding export capacity.
Looking deeper, the formation of the cluster has stimulated the rise of related service industries—supporting activities such as irrigation technology, agricultural technology, packaging and logistics, and testing and certification have begun to agglomerate around Jazan. This is a practical embodiment of Marshallian agglomeration economies. Government financing here acts as the "initial spark," while the real scale effects are achieved through market forces and the compounding effect of time.
Beyond Agriculture: The Cross-Sector Reach of Development Finance
Saudi Arabia's experience has not been limited to agriculture. In the new city of NEOM, the National Development Fund, together with local and international banks, financed a green hydrogen plant with 10.3 billion riyals (about $2.7 billion). This is not just mega-project financing; it is a strategic fulcrum for Saudi Arabia to promote its energy transition and establish itself as a hub for green hydrogen exports. Similar to the coffee cluster, green hydrogen also depends on regional endowments (sunlight, land, ports), and policy-based finance reduces upfront risks to attract multinational participation.
In addition, the Saudi National Development Fund also covers tourism in Aseer Province, the olive oil industry in AlJawf Province, and emerging technology sectors in various regions. This "one province, one cluster" strategy is gradually shifting the original oil-centric monocultural economic structure toward a diversified ecosystem, and it aligns with the goals of Vision 2030 to enhance balanced regional development and the quality of life of citizens.
Implications for the Global Investment Landscape
Saudi Arabia's case offers significant lessons for the Global South and other middle-income countries. First, the "coordination capacity" of development finance matters more than the "scale of funds." Many developing countries have multilateral development banks or national development banks, but often fail to form synergies due to fragmented institutional structures. The NDF's matrix model provides a governance template.Secondly, development finance should move counter-cyclically. During economic downturns or contractions in private capital, public financing needs to step in to stabilize investment expectations. Saudi Arabia's continued advancement of long-term projects such as green hydrogen amid fluctuations in oil revenue exemplifies this strategic resolve.
For multinational enterprises, understanding the development finance ecosystem of the host country means identifying investment entry points with greater precision. Government-supported industrial clusters often have more developed infrastructure, lower compliance costs, and potential tax and financing incentives. The expansion of the Jazan coffee industry chain has already created a window for related agricultural technology and food processing companies to enter Saudi Arabia.
Conclusion: Cluster Competition Is the Theme of the Next Decade
The restructuring of global industrial chains is no longer defined solely by national borders, but is increasingly concentrated at the level of micro-regional clusters. As an institutional tool, development finance can effectively lower the barriers to agglomeration and accelerate the spatial reorganization of production factors. From Saudi Arabia's experience, the core lies not in "government leadership" but in "government creating conditions for the market."
In the future, countries and regions that can integrate development finance, locational advantages, and innovation ecosystems will be more likely to prevail in intense global competition for capital. For research institutions, policymakers, and investors, observing the emergence of such new regional economic clusters may be the key to grasping the pulse of the next round of globalization.
