Competitividad de la acuicultura espa？ola: modelos explicativos

the aim of this paper is to determine explanatory models for the competitiveness of spanish aquaculture, contrasting the effect of endogenous factors on the theory of resources and capacities in the above-mentioned models. after the obligatory theoretical review, the methodology consists of contrasting and verifying two hypotheses about the applicability of the above-mentioned theory to empirical research that combines results from a survey and ratios extracted from the sabi database of 99 spanish aquaculture companies (using the spss and amos programs). the results obtained (factorial and path models of structural equations) indicate the differential incidence or prevalence of certain variables over others contained in the theory, for the case of competitiveness in spanish aquaculture. from the re-specification of the proposed models, we can conclude that the competitiveness of spanish aquaculture relates to the generation of value, productivity, size, innovation and specialization.
