The purpose of this study is to examine the relationship between trade and labor productivity. We focused on the export and import portion's effect on labor productivity. In analyzing the relationship between two variables, the preceding research used firm level data, which means that it estimated only the volume effect and not the industrial effects. In studying industrial effect, we can derive implications about governmental policy. Furthermore, we can determine the difference between service and non-service industry using the multi-level model. It is very important because the service industry will gain much more attentions with time. Our research results show that the export and import portion has a positive effect on labor productivity, and there is no statically significant difference between service and non-service industry.
