Abstract
By extending Gini coefficient in the classical economics, we put forward the concept “the steel capacity competitiveness - capacity income Gini coefficient”, namely TCC, to reveal the non-equilibrium problems. Considering the comprehensive factors which influence steel industry competitiveness capacity, AHP was used to construct the evaluation model of steel industry capacity competitiveness. The numerical computation is done by Matlab to calculate the weight of each factor. The computation value of TCC of Chinese steel industry in 2006 is 0.4192. As the revenue Gini coffeicient, now it indicates the deviation of capacity competitiveness contribution income between is bigger. By the TCC analysis, there are only 3 enterprises, Jiangsu steel and Baosteel and Capital steel,whose Tcc is greater than 1. And the contribution of these three enterprises are biggest. TCC provides an downsized index to improve steel industry overcapacity.
