Este trabajo explora la formación de grupos estratégicos en el Sector Bancario Español, a partir de una definición alternativa de grupo estratégico (GE). Un GE se define como un conjunto de empresas capaces de responder del mismo modo a perturbaciones. La capacidad de respuesta, o capacidad de adaptar la estrategia competitiva, se define a partir de las relaciones marginales (RM) entre las variables estratégicas (la pendiente de la frontera en un punto), y sirve de base para examinar la presencia de barreras a la movilidad. El Análisis Envolvente de Datos (DEA) es la herramienta utilizada para el cómputo de las RM, aunque su uso genera dos problemas que son solucionados en este trabajo; la multiplicidad de RM para las empresas situadas en la frontera (líderes estratégicos), y la imposibilidad de encontrar RM para las empresas situadas por debajo de la misma (seguidores estratégicos).
