On the one hand, Spain had to adopt EU legislation, which does not consider Free Trade Zones to be industrial in nature, but rather points of entry for products from third countries free from taxes or duties, and on the other hand, the country's economy became entirely open, functioning with a series of different parameters.
Por unha banda, España tivo que someterse á lexislación comunitaria, que non concibe as zonas francas como lugares industriais senón como puntos de entrada de produtos de países terceiros, sen impostos nin aranceis e, doutra banda, a economía pasaba a ser absolutamente aberta e a funcionar con outros parámetros.
