South Korean tourism is driven by many factors, including the prominence of Korean pop culture such as South Korean pop music and television dramas, known as the Korean Wave or (Hallyu), has gained popularity throughout East Asia. The Hyundai Research Institute reported that the Korean Wave has a direct impact in encouraging direct foreign investment back into the country through demand for products, and the tourism industry. Among East Asian countries, China was the most receptive, investing 1.4 billion in South Korea, with much of the investment within its service sector, a sevenfold increase from 2001. According to an analysis by economist Han Sang-Wan, a 1 percent increase in the exports of Korean cultural content pushes consumer goods exports up 0.083 percent while a 1 percent increase in Korean pop content exports to a country produces a 0.019 percent bump in tourism.
