Incheon's main bet is biotech. The Songdo cluster had about 80 companies and 10 research institutes in 2022, with 880,000 liters of production capacity. That was billed at the time as the world's largest. Barcelona's tenants are mostly older industry.
FTZ News: Incheon's zone is a state-designated investment district spread across three planned cities, an airport and a seaport. Barcelona's is an industrial estate with a customs enclave, run by a public consortium that's been around since 1916. The consortium manages industrial and logistics property. One side was built to pull in foreign capital. The other mainly manages land and logistics.
Neither side publishes a clean ledger of its own exports, imports or payroll. The numbers that exist come from different years and different definitions. Where zone-level figures are missing, regional ones are used below and labeled as such.
Size and structure
Incheon is far larger. The zone authority puts its current area at 122.34 square kilometers, counting the airport and port. Barcelona's estate covers six million square meters. A big chunk of Incheon's land is airport and port, so the gap in actual industrial space is smaller than the raw numbers suggest.
Incheon was designated in 2003. Barcelona's consortium is more than a century old. Companies in Incheon can get tax reductions and administrative help. The Barcelona consortium answers to Spain's Finance Ministry and makes most of its money leasing industrial and logistics space. Control of the consortium is shifting. In May, the Catalan government and Esquerra Republicana reached a deal that would give Catalonia 55 percent. The published terms don't make clear whether that means transferring ownership or just changing how the consortium is governed.
What they produce
Incheon's main bet is biotech. The Songdo cluster had about 80 companies and 10 research institutes in 2022, with 880,000 liters of production capacity. That was billed at the time as the world's largest. Barcelona's tenants are mostly older industry. Seat, Ebro, Covestro, DB Schenker, Consum, FCC and Wallbox are on the list. A 2016 survey put 43 percent of companies in industry, 31 percent in logistics and 25 percent in services.
Production value
Production numbers are hard to line up. Resident companies in Incheon reported 78 trillion won in sales for 2019. Barcelona has no equivalent figure for its tenants. What it publishes is the consortium's own books: a 2025 budget that forecast 67.9 million euros in turnover. That's the consortium's revenue, not what the companies inside the zone produce.
Exports and trade
Incheon's exports lean toward chips, drugs, cars and cosmetics. In the first half of 2026, pharmaceuticals alone brought in $4.07 billion. Barcelona's trade runs mostly toward Europe. For Catalonia, the European Union takes more than half of exports. The wider Incheon region exported $60.1 billion in 2025. Catalonia sold a record 100.8 billion euros abroad the same year.
Trade balances
The trade balances go in opposite directions. Incheon ran a $660 million surplus in the first half of 2026. It didn't hold. Catalonia imports more than it exports. Official figures put its 2025 deficit at 14.46 billion euros. Neither free zone reports a trade balance of its own.
Jobs
Employment numbers are thin and old on both sides. Incheon's last survey counted 103,693 people at the end of 2019. No dated zone-level headcount for Barcelona turned up. The consortium's DFactory expansion is projected to add 1,500 direct jobs.
Foreign investment
This is where Incheon pulls ahead. The zone had recorded $16.72 billion in declared foreign direct investment by the third quarter of 2025. In 2023, IFEZ accounted for more than 70 percent of all declared investment across South Korea's nine free economic zones. Barcelona doesn't track foreign direct investment at the zone level.
The bottom line
Which model works better depends on what you're measuring. Incheon has the scale, the foreign investment numbers and a clear sector focus. Barcelona has continuity and a tenant list that still anchors a chunk of Catalonia's industrial base. Neither zone publishes the figure that would settle most of the arguments: how much of the trade moving nearby actually belongs to the zone itself.
