The research of sustainable development for Iron & steal enterprises based on ANP

This paper introduces a new method-analytic network process (ANP) to establish a new evaluation index system, analyses influences and independences between the indexes. There by enhanced the feasibility and reasonability of index weights. The results show the management capacity in the iron and steel enterprises holds the maximum proportion to contribution of the sustainable development (0.3453). Other contribution arrangements are in turn the enterprise resource utilization, business innovation and environmental protection capacity. In enterprise's management capacity, the growth factor is biggest to sustainable development target contribution, and then is the scale factor and the efficiency factor. From the individual index rankings, standing in the front five, in order, comprehensive energy consumption for every tonne of steel (0.0633). Metric tons of steel material consumption (0.0626), metric tons ore consumption (0.0512), metric tons of fire-proof material consumption(0.0474) and the scale of investment in technology (0.0546).We can see that the constraint of steel enterprises as a key to sustainable development lies in the enterprise resource utilization capacity. The article has provided the new mentality for the iron and steel enterprise sustainable development appraisal has the certain reference value.
