In this study, we investigated the factors influencing the exports of horticultural sector in Korea. In particular, we estimated the gravity-type export equations for three horticultural products. The findings of this study are as follows. First, the effects of distance on the export of horticultural products except fruit are significant. Second, complementation in trade has positively related with export of horticultural product, except fresh vegetable. Trade of fresh vegetable are more likely to be intra-industry trade rather than inter-industry trade due to the difference of cropping period. Third, foreign direct investment does have a significant positive effects on the export of fresh vegetable and flower. Fourth, tariff is positively related with export of fresh vegetables, and the entry into WTO has significant positive effects on the export of fresh fruit. The results implies that neighborhoods including China, Japan, and emerging Asian countries become more important exporting market of horticultural sector. And foreign direct investment and trade specialization is also important to increase the export of horticultural product.
