This article discusses the determinants of economic growth of local tourism markets in Korea using a spatial econometric model. The model is applied to the East Coast Energy-Tourism Belt including Gangwon, Gyeongbuk, and Gyeongnam provinces. This paper finds that the market sizes of local tourism are determined by the number of tourists, the regional economic factors such as the population size and the financial independence rate of local governments, and the infrastructure factors such as the length of road and the location of railroad station. If there is an increase in the financial independence rate by 1%, the market size could be expanded by 0.98%. The location of railroad station and the road construction have positive impacts on the market size of tourism, too. But the population has could lead to a marginal growth of tourism market.
