Stratégies d'approvisionnement et d'innovation des entreprises de transformation des produits de la mer

The seafood processing industry (SPI) is based on a natural renewable and common resource, these properties are different from those of agricultural resource. Can this distinction called in question the transposition of the model of development of the food processing industry to the SPI ? More precisely, can this distinction created differences concerning supply and innovation strategies between the two industries? To treat the problem, we join together two fields of investigation generally treated in a disjoined way : fishery economy and industrial organisation. We used a bio-economic model to analyse the incidence of the common-property of living marine resources. It shows some particularities on tree way : the expansion of the market, the supply strategy and innovation behaviour. To verify these results in the French case, we developed a methodology inspired by the Structure-Conduct-Performance paradigm. We also used the product life cycle theory and some concepts of the evolutionary theory. The application of the methodology required the collection of information starting from pre-existent data. These information led to a typology of the behaviours. Moreover, we examined the performances of the innovation strategies. The results show that the particularities of fishing industry are reflected clearly on supply behaviours but they are less influential on innovation strategies ; they are also reflected on the development of the industry of the products frozen by limiting the growth of the market, phenomenon likely to be reproduced with other divisions of the IHA.
