Abstract: The factors that explain the level of intra-industry trade and its share of total trade in a multi-country version of the Helpman-Krugman model are derived. The role of similarity of endowment ratios and similarity of economic sizes differ in the multicountry version from the two country version of this model. It is also demonstrated that the volume of total trade, the volume of intra-industry trade and the volume of interindustry trade can each be described by a modified gravity equation. A new diagrammatical device is introduced that illustrates the relationship between trade volume and similarity in country size.
