The missing link in GBA’s global ambitions

By Ryan Ip, Jason Leung and Moon Kok Share Around the world, three great bay areas — Tokyo, San Francisco, and New York — have long defined the pinnacle of urban economic organization. While each has forged a distinct path to global competitiveness, a common theme is that their success does not hinge on the individual prowess of any single city but on the seamless integration of their entire ecosystems. The Guangdong-Hong Kong-Macao Greater Bay Area now stands at the same crossroads, competing not as a collection of cities but as a unified economic powerhouse. With the 15th Five-Year Plan (2026-30) kicking off, coordinated regional development should logically take center stage. In the new era of high-quality development, the true measure of an airport cluster is no longer simply how many runways it boasts but how efficiently it moves people and resources. Without fast rail links and clear functional synergy, even the most ambitious capacity expansion risks creating little more than glorified internal competition. The central challenge is clear: How to transform the Greater Bay Area’s sizable airport cluster into an integrated, efficient, and mutually reinforcing hub system. Benchmarking the world’s leading bay areas, their successful airport systems begin with deep functional complementarity, offering clear lessons for the Greater Bay Area. The Tokyo Bay Area shows the power of policy guidance. Although different companies operate Narita and Haneda airports, the Japanese national strategy assigns each a distinct role — Narita focuses on long-haul international flights, while Haneda handles domestic and business routes. The result is a stable, durable collaboration. The San Francisco Bay Area offers a market-driven alternative. Through healthy competition, San Francisco, Oakland, and San Jose airports have naturally evolved distinct identities — an international gateway, a domestic low-cost hub, and a node serving the tech hinterland.
