Once wracked by political chaos and poverty, South Korea has emerged as an Asian giant whose economy stands tall amidst a number of other competitors. Little wonder then, its spectacular economic growth has been popularly called the "Miracle of the Han River"! Now a trillion-dollar-club economy that ranks as the world’s 12th largest, with a gross domestic product of $ 1.4 trillion, South Korea has only one track that lies ahead of it: that of sound growth, provided the government is able to implement its economic innovation plan.  

Going back in time, South Korea, also known as the Republic of Korea, suffered huge losses during the Korean War that lasted from 1950 to 1953. By the time the war ended, the nation’s economy was in a shambles, infrastructure was destroyed and there was heavy dependence on U.S. aid. However, the country’s transformation from poverty to affluence has been phenomenal. South Korea became part of the Organization for Economic Cooperation and Development (OECD) in 1996. There has been no looking back since then, and today it is a fast growing, highly industrialized nation that can serve as a role model for all developing nations. An important contributor in this growth process is the culture of innovation that prevails in South Korea, an atmosphere that is friendly for investors and extremely cordial relations with most of the countries in the Asian market.

GDP Composition

South Korea is categorized as a "high-income OECD" nation by the World Bank and is largely supported by its industrial and services sector, which contribute 38.2% and 59.5% to the nation’s gross domestic product. A meager 2.3% comes from the primary sector per the 2014 data.

Agriculture

In the initial years after the division of the Korean peninsula, agriculture contributed almost 50% of the nation’s GDP, but South Korea has been fast in shifting its base to the industrial sector. The primary sectors’ contribution dropped to 15% by 1980s, sliding down below 10% by the late 1980s and has stayed sub-5% since 1998. The agricultural sector, including forestry, hunting, and fishing, as well as cultivation of crops and livestock production, currently employs a mere 6% of the population and contributes a small share of 2.3% to the GDP. 

South Korea’s rugged topography leaves little scope for agricultural cultivation, as only 16% of the total land is arable. Therefore, the country has to rely heavily on the import of agricultural products and raw materials for processing. With increasing urbanization and rising labor costs, people have moved away from the agricultural sector. The small production sector that remains is substantially dependent on government subsidies and protectionist trade policies. South Korea now imports feed grains, soybeans, wheat cotton and animal hides to operate its livestock, flour milling and export-oriented industries such as textiles and leather goods.

The major suppliers to South Korea for its food requirements are the U.S. (corn, meat, hides, soybeans, milling wheat and cotton), China (starch and brew residues, frozen and preserved vegetables, rice, processed foods, soybeans), Australia (beef, wheat, sugar, dairy products), European Union (pork, wine, processed foods, dairy products), ASEAN (rubber, palm oil, bananas, oilseed meals), Brazil and Argentina (soybeans, soy meal, soy oil) and New Zealand (beef, dairy products, kiwifruit). 

Industry

The industrial sector has been a consistent contributor to the nation's GDP over the years, absorbing approximately one-fourth of its labor force. Within industry, which is composed of manufacturing, mining, construction, electricity, and water and gas as its subsectors, manufacturing has been the engine of economic progress, especially during the 1980s. Of the 34% share of industry to South Korea’s GDP, 23% was contributed by manufacturing alone in 1980. The share increased to 25% of the 39% contribution of the industrial sector in 1991 and in 2014, while manufacturing contributed 30% of the 38% industrial sector share to the gross domestic product.

Other than manufacturing, mining activity has witnessed steady growth, although it is limited to a few metals and minerals. South Korea is a leading steel, cadmium and zinc producer. The country also has small reserves of copper, gold, iron ore, lead, tin, antimony, silver and tungsten; however, domestic resources have not been able to cater to the demand of the industrial sector. Thus, South Korea needs to import mineral commodities to fill the gap. 

South Korea’s largest industries are electronics, automobiles, telecommunications, shipbuilding, chemicals and steel. The country is among the largest manufacturer of electronic goods as well as semiconductors, with globally popular brands such as Samsung Electronics Co. Ltd. and Hynix Semiconductor (SK Hynix Inc.). The country’s automotive industry is highly developed and has a huge capacity for automobile production. Some of the well-known Korean brands are Hyundai, Renault and Kia. South Korea’s government support has made the country one of the most active markets for telecommunications and information technology. It is a booming mobile market and has the highest number of broadband services per capita in the world. South Korea is a world leader in shipbuilding; five out of the top ten enterprises (including the top four) are South Korean companies, with Hyundai Heavy Industries Co., Ltd. owning the largest shipyard in the world.

Services

The tertiary industry or services sector has gradually risen in terms of its contribution to the country’s GDP; from about 39% of the nation’s GDP back in 1965 to 50% by 1980 to 60% in the present times. However, the sector is yet to reach its optimal potential, as much of its growth has come by adding employees rather than through improving productivity. The sector provides employment to 70% of the Korean workforce. According to a report by the OECD, “By 2012, service sector productivity was only 45% of that in manufacturing, far below the OECD average of 86%.” South Korea also lags behind countries like Japan (73%), the U.S. (78%) and the U.K. (79%) in terms of the share of GDP supported by the service sector. 

President Park’s three-year plan for economic innovation will provide a boost to the services sector, which can help reduce the country’s dependence on imports. According to the president’s proposal, research and development (R&D) in service sector will be financially supported, and efforts will be made to bring its level closer to that in manufacturing. The small companies that dominate the service sector will be provided with the much-needed investment and R&D. The service sector should play a major role in the years to come as investment increases in areas like medical care, tourism and education, which would in turn become employment generators for the nation’s youth.

The Bottom Line

South Korea has moved at a fast pace since the bifurcation of the Korean peninsula. The adoption of capitalist ways has worked well for the nation, which today is characterized by low unemployment, moderate inflation, an export surplus and a fairy equitable distribution of income. However, a number of challenges remain in the form of an aging population, rigid labor market, heavy dependence on imports and limited domestic market. (See also: North Korean Vs.
