A coalition of South Korea’s top 100 firms generated an economic contribution of 1,615.2 trillion won in 2024, marking a 3.9 percent rise from the previous year, according to CEO Score data released on 18 June. Samsung Electronics led the charge with a 7 percent increase to 157.5 trillion won, accounting for 9.8 percent of the total haul.
This growth reflects an integrated model of wealth distribution across stakeholders—suppliers, workers, government, shareholders and communities. Total sales of these firms reached 2,122.4 trillion won, growing 6.6 percent year-on-year, underlining the deep economic interlinkages driving expansion.
Hyundai Motor secured the second position with a contribution of 115.2 trillion won, followed by Kia at 86.6 trillion won, which spectacularly posted the steepest increase thanks to surging supplier payments. Among the top ten contributors were LG Electronics, Hyundai Mobis, GS Caltex, SK Energy, Posco, Samsung C&T and LG Chem. In contrast, LG Energy Solution saw a pronounced drop of 28.3 percent to 19.2 trillion won, weighed down by lower stakeholder payouts.
Industry breakdown highlights that electronics and IT firms contributed about 370 trillion won, followed by petrochemicals at 312 trillion won and the auto sector at 303.5 trillion won. Construction, shipbuilding, steel and distribution made further sizeable additions, reflecting a diverse industrial base.
The dominance of chaebol giants—especially Samsung—continues unabated. Samsung and its affiliates, constituting nearly a quarter of national GDP, help drive national innovation and exports. Beyond scale, these conglomerates are embracing strategic shifts. Government figures show a record R&D investment of 83.6 trillion won by South Korean firms, with Samsung alone ploughing 30.2 trillion won into innovation, followed by SK hynix at 4.5 trillion won, Hyundai at 4.3 trillion won, and LG Electronics at 3.4 trillion won.
Despite stepping up R&D budgets by 15.3 percent, only 40 domestic firms made the global top 2,000 by R&D outlays, compared to 681 in the US and 524 in China—underscoring scope for further thrust in innovation. Within semiconductors, South Korea continues to hold a dominant global footprint, commanding approximately 60 percent of the DRAM market and 52.6 percent of NAND, led by Samsung and SK hynix. Notably, SK hynix claimed 36 percent of DRAM market share in Q1 2025, overtaking Samsung’s 34 percent.
This data reveals a dual narrative: chaebol behemoths remain the backbone of the economy, but a growing reliance on innovation and global competitiveness is reshaping the corporate landscape. Hyundai’s pivot to electric vehicles, Kia’s ramped-up supplier integration and LG’s diversification into chemicals and energy solutions are emblematic of this shift.
However, concentration risk persists. Samsung and its affiliates form a significant share of GDP and exports, but reliance on a limited set of heavyweights may expose the economy to global headwinds. The comparative lag in R&D-intensive mid-sized firms risks stifling long-term resilience.
Nevertheless, public policy is responding. Regulatory tweaks aimed at supporting corporate research and streamlining licensing protocols, alongside financial incentives and infrastructure development, suggest a proactive stance to broaden innovation beyond the chaebol core.
As South Korea navigates economic turbulence—from fluctuating global demand to supply chain uncertainties and U.S.–China tech tensions—the measured expansion of stakeholder-driven value and intensification of R&D efforts signal a strategic repositioning.
