Market Power in South Korea: Balancing Growth and Fair Competition

 

Market Power in South Korea: Balancing Growth and Fair Competition

By Anushka Rajiv

South Korea is one of the most remarkable economic success stories of the modern world. In just a few decades, it transformed from a war-torn nation into a global technology and manufacturing powerhouse. Yet, behind that achievement lies a persistent challenge: a highly concentrated economy dominated by a few powerful conglomerates, known locally as chaebols.

Companies such as Samsung, Hyundai, LG, and SK account for a large share of South Korea’s exports, investment, and employment. According to the Korea Fair Trade Commission (KFTC), the top ten conglomerates control more than half of the country’s total corporate assets. This concentration gives them enormous influence over prices, wages, and innovation. While the chaebols helped fuel South Korea’s rise, their market power has also created inequality and limited opportunities for smaller firms.

Economists warn that when a handful of corporations dominate major sectors, competition can suffer. In industries such as electronics, automotive manufacturing, and telecommunications, smaller companies often struggle to enter the market or expand. This limits entrepreneurship and keeps much of the country’s economic power in the hands of a few families and boards. Recent research from Seoul National University found that firms linked to large conglomerates earn on average three times more profit than independent competitors, even when operating in the same industries.

The government has taken steps to address these imbalances. The KFTC introduced new regulations in 2025 aimed at increasing transparency in business practices and preventing unfair cross-shareholding between affiliated companies. The reforms seek to make markets more open and competitive while reducing the dominance of family-controlled groups. Still, critics argue that enforcement remains weak and political influence from major corporations continues to shape economic policy.

For ordinary citizens, this concentration of market power has real consequences. Small and medium-sized enterprises, which employ more than 80 percent of South Korea’s workforce, often face high barriers to credit and limited access to supply chains dominated by the chaebols. Wage disparities persist between employees of large firms and those in smaller ones. Consumers also see fewer choices in some markets, particularly in technology and finance.

Balancing growth with fairness remains one of South Korea’s greatest economic challenges. The country owes much of its success to the innovation and global reach of its major corporations. Yet its future competitiveness will depend on building a more inclusive economy—one that rewards creativity, supports smaller businesses, and ensures that prosperity is shared more equally across society.
