Abstract
This study investigates the determinants of the international promotion of the Korean language at the cross-country level. The analysis is based on candidate data drawn from the Test of Proficiency in Korean (TOPIK) and uses a cross-country panel data model to measure how several factors affect Korea's international promotion. To mitigate sample selection bias, we estimated the model using the Heckman two-step method. The findings show that factors such as the Hallyu (or "Korean Wave"), international business, motivation to migrate to South Korea, motivation to study in South Korea, and Korean language learning resources play essential roles in the international promotion of Korean. The development level of the sample countries influenced the importance of each factor. For example, Hallyu, often regarded as important for the international promotion of Korean, was shown to be statistically significant only in the sample of developed countries. In addition, a shortage of Korean language learning resources has been identified as a major impediment to the promotion of Koreans in developing countries. These results provide new insights that can assist in formulating policies to promote the Korean language worldwide.
