La similitude dans l'échange international : une revue critique des approches


  • Joël Hellier


[fre] La première partie de l'article présente une revue critique des princi- pales approches des échanges de similitude (« intra-branche » et commerce entre pays similaires). La présentation s'appuie sur trois critères : (1) la relation à l'avantage comparatif, (2) la place des économies d'échelle et de la differentiation des produits et (3) les imperfections de marché et les entraves à la concurrence. Dans la seconde partie, différentes formes de similitude sont distinguées. La similitude peut d'abord concerner les produits (échanges intra-branche) ou les pays (échanges entre pays similaires). Pour les produits, on peut séparer la differentiation en termes de demande, la similitude technologique et les biens identiques (homogènes). Cette classification permet de distinguer les facteurs explicatifs et les différentes approches selon le type de similitude auquel elles se rapportent. [eng] For thirty years, numerous explanations of intra industry trade and trade between similar countries have been developed. The first part of this paper is a critical survey of these theories, classified according to the criterias on which they are based: (1) comparative advantages, (2) the economies scale and product differentiation and (3) the market failures and barriers to competition. In a second part, a classification of the different forms of similitude is presented. A first distinction concerns trade of similar products on the one hand, trade between similar countries on the other. The products can themselves be regarded as (1) demand- differentiated, (2) technologically similar and (3) identical (homogeneous). This classification shows that the factors and theories previously presented often deal with different forms of similitude.
