Competitiveness advantage analysis as one method for cluster identification in regions

The cluster birth process must start with identification of industrial branches strengths which are the fundaments for cluster increasing. When the cluster establisher will continue in this process the final result - cluster need not be the most effectiveness result and all money will be wasted. For cluster identification can be used some approaches. The first approach follows the identification of key industrial branches having the potential (or real) competitiveness advantage. This identification proceeds by the statistics data analysis (mostly quantitative data). The second approach investigates the internal processes and relations among existing firms. It uses the qualitative data what are obtained from interviews or question-forms. The combination of both mentioned approaches is the most effectiveness process. In this case the missing data can be compensated from the second approach, or the concrete relations and their mentions can be understand. This approach must be realized in cluster potential analysis in specialized industrial branches. There are many various methods for cluster identification in literature sources. But no more methods are applicable in practice because of the data are not available. Presentation of method based on Porter diamond model is goal of this paper. This method is the combination of quantitative and qualitative methods. We can name it as method of competitiveness advantage analysis.
