    [eng] Definition and measurements of two-way trade in similar products : a re-examination K. S. Abd-El-Rahman The concept of " intra-industry " trade in economic literature is ambiguous. Mainly, confusion is made between the existence of two-way trade in similar products between countries, and commercial balances which may appear at the level of such trades. According to the approach that we propose, attention is made, first, to apply a precise definition of product similarity, and, second, to consider two-way trade in similar products in its totality and not as equilibrated parts of exports and imports of some aggregated trade statistics. Applying this approach to intra-EEC trade of manufactured goods revealed that simultaneous exports and imports of similar products actually take place. Thus the distinctive consideration of the "export" and the " import " parts in a two-way trade flow allowed for the observation of commercial balances, which can be negative or positive, of two-way trade. The results shoived that two-way trade in similar goods has several patterns, and is not only bilateral. The phenomenon fluctuates significantly depending on the activity and on the partner. However, the partner of the trade is shown to be the most influencing factor in the variation of phenomenon. [fre] Les échanges dits « intra-inclustrie » on « intra-branche » correspondent, dans la littérature économique1, à un concept imprécis. La majorité des approches actuelles créent surtout un amalgame entre le concept de l'existence des échanges croisés de produits similaires entre les nations, et les soldes qui peuvent apparaître au niveau même de ces échanges. En se référant au concept de produit, la démarche que nous proposons consiste, en un premier temps, à bien définir la similarité de produits, et à considérer ensuite les échanges croisés de produits similaires en leur totalité et non pas en partie. L'application de cette approche sur le commerce ultra-CEE de biens manufacturés, a montré l'existence réelle des simultanéités d'exportations et d'importations de produits similaires au niveau des économies nationales étudiées. Les résultats montrent également que ces échanges sont même très développés dans le commerce intra-communautaire. Cette approche a permis, par la prise en compte distincte de la partie exportation et de la partie importation dans l'échange croisé clé produits similaires, de faire apparaître les soldes de ces échanges. Les résultats et l'évaluation de la part des échanges bila­téraux clans l'observation multilatérale du phénomène, tend, à soutenir que le com­merce croisé de produits similaires est de plusieurs types, et non pas strictement bilatéral. Le phénomène varie significativement selon l'activité et selon le parte­naire. Toutefois, les résultats montrent que c'est l'effet « partenaire de l'échange » qui influence le plus la variation du phénomène.
