Evaluation of the efficiency of the Spanish textile industry using economical–financial information: an application of evolved data analysis

There is no competitiveness problem when there are no competitors. For that reason, differentiation constitutes a key strategy for the company; then it contributes to generate a captive market for the product reducing this way its competition. Supposing that differentiation is not possible, costs and efficiency appear as the only possible way. Focusing the attention in the last one, this paper analyzes – by employing a non parametric methodology: the data envelopment analysis (DEA) – the technical efficiency of textile industry in Spain. For that, we have studied a group of companies of each and every activity that constitute the textile industry following the classification CNAE93. The evaluation has been done from financial–economic information obtained from the profit and losses account and balance sheet.
