Firstly, it seeks the sources from which theories have been developed, by a summary of evolution or a road-map. Secondly, it explains the two basic forms taken by traditional theories on intra-industry trade, namely, horizontal intra-industry trade model and vertical intra-industry trade model. Both models take final products as trade objects and products of same industry are thus simultaneously exported and imported among developed nations and among developed nations and developing ones.Thirdly, it points out that the theory of vertical intra-industry trade has already been expanded in scope in the area of trade between developed countries and LDCs. It shows that the implication of vertical intra-industry trade has expanded to the importation and exportation of parts and components, intermediate products or processing products produced via various working procedures or different production links within the same industry, with MNCs as carriers. It gives the summary of the methods of measuring intra-industry trade and argues that the basic method adopted by this thesis is G-L Index. In addition, GHM and Input-output Analysis are introduced to demonstrate the expansion of vertical intra-industry trade.
