The aim of this work is to analyse the different impact of competitive environment changes across different indicators in the competitive environment on the Spanish companies of the textile and apparel industry. The results obtained from the contrast upon a sample composed by 5.531 SME’s of this sector show a important role of the territory and of the strategy of internationalization. For this reason, given the trend of this industry to the concentration and geographical specialization it is expected that the effect of these changes is irregular and asymmetrical between the main producing Spanish regions.
