Evaluation on International Competitiveness of Coal Industry Based on Objective and Subjective Integrated Method

The system of evaluation indicator system for coal industry competitiveness is put forward based on coal industry reality. The comprehensive model of integrating Interval Analytic Hierarch Process (IAHP) and Entropy weight is established in this paper based on the theories and methods of IAHP and Entropy. The entropy weight is adopted in this model; the subjectivity which lies in ascertaining factors´ weight in lower hierarchy was avoided. Meanwhile, the IAHP is adopted in this model can put the experts´ knowledge into consideration. The evaluation model is applied in the 11 main coal production countries in the world. The empirical study validates the model as scientific and feasible in practice.
