Is South Korea’s economic miracle over?

Outside the town of Yongin, 40 kilometres south of Seoul, an army of diggers is preparing for what South Korea’s president has described as a global “semiconductor war”.The diggers are moving 40,000 cubic metres of earth a day, cutting a mountain in half as they lay the foundations for a new cluster of chipmaking facilities that will include the world’s largest three-storey fabrication plant.The 1,000-acre site, a $91bn investment by chipmaker SK Hynix, will itself only be one part of a $471bn “mega cluster” at Yongin that will include an investment of 300tn won ($220bn) by Samsung Electronics. The development is being overseen by the government amid growing anxiety that the country’s leading export industry will be usurped by rivals across Asia and the west.“We will provide full support, together with SK Hynix, to ensure that our companies won’t fall behind in the global chip cluster race,” South Korea’s industry minister Ahn Duk-geun told SK Hynix executives during a meeting at the Yongin site last month.Most industry experts agree the investments at Yongin are required for South Korean chipmakers to maintain their technological lead in cutting edge memory chips, as well as to meet booming future demand for AI-related hardware.But economists worry that the government’s determination to double down on South Korea’s traditional growth drivers of manufacturing and large conglomerates betrays an unwillingness or inability to reform a model that is showing signs of running out of steam.Having grown at an average of 6.4 per cent between 1970 and 2022, the Bank of Korea warned last year that annual growth is on course to slow to an average of 2.1 per cent in the 2020s, 0.6 per cent in the 2030s, and to start to shrink by 0.1 per cent a year by the 2040s.Pillars of the old model, such as cheap energy and labour, are creaking. Kepco, the state-owned energy monopoly that provides Korean manufacturers with heavily subsidised industrial tariffs, has amassed liabilities of $150bn. Of the other 37 OECD member countries, only Greece, Chile, Mexico and Colombia have lower workforce productivity.Park Sangin, professor of economics at the graduate school of public administration at Seoul National University, notes that South Korea’s weakness in developing new “underlying technologies” — as opposed to its strength in commercialising technologies like chips and lithium-ion batteries invented in the US and Japan respectively — is being exposed as Chinese rivals close the innovation gap.Diggers are moving 40,000 cubic metres of earth a day as they lay the foundations for a new cluster of chipmaking facilities in Yongin More
