Trade where goods of the same classification are both imported and exported. In some cases this results from seasonal factors: for example, a country may export apples in the autumn and import them in the spring. In other cases the reason is transport costs: a large country may export goods over one border and import similar goods over another. In most cases, however, intra-industry trade results from economies of scale. It allows consumers to have access to numerous varieties of a type of good, of which the country produces a few on a large scale, which it exports, and imports the others. Intra-industry trade is contrasted with inter-industry trade, which arises from differences in resources between countries, so that any type of goods is normally exported or imported, but not both.
