The expert group conducted research based on Porter's "Diamond Model" ,in combination with the authoritative data released by the government and industry organizations. The expert group adopts analytic hierarchy process and expert empowerment method to build an industrial competitiveness model with five dimensions: industrial chain competitiveness, R&D innovation competitiveness, talent competitiveness, capital competitiveness and product market competitiveness. In the model, the expert subjective weighting method and objective weighting method are used to calculate the indicators of industrial competitiveness system. At the same time, the comprehensive rating and analysis of Baoji high-tech industry are carried out based on the field survey data and expert weighting value.
