A Theoretical Approach to the Concept of the Cluster

A cluster is an important way to increase the economic development in a region. The discussion about the most suitable meaning of a cluster is breadth. For this reason, the main aim of this research was to provide a general overview of the concept of the cluster. The methodology is a review of literature of the main theoretical- empirical studies and models and some proposed models as well as its importance as a strategy for regional development and its operation. The main conclusions are that all the theoretical approaches to the concept are relevant and that does not exist a unique approach to define cluster.
