pare the technological innovation of enterprises petitiveness between our panies, so that enterprises can not improve their less than intuitive to increase the level of technological innovation. This article is from the iron and steel enterprises in technology innovation evaluation system of indicators selected to proceed the important single criterion in the AHP method for the calculation of the weight applied to the TOPSIS method to evaluate the iron and steel enterprises in technology innovation and petitiveness of large steel panies can make progress when pared to external innovation while improving their ability to innovate.. Notations and definitions(1) X={x1,x2,…x n}: A set consisting of iron and steel enterprises which is waiting for technological innovation petitiveness.(2) U={u1,u2,…u m}: A set of rating indicators.(3) W={w1,w2,…w m}T: A vector of index weights.(4) a=:Closed interval number, 、R3. How to establish Rating model . Classification EvaluationWe used oneyear data as the evaluation objects for large iron and steel enterprise technology innovation index. But largescale iron and steel enterprises is characterized by a long cycle of technological innovation, updating innovative technology is slow and a lot of research for many years so we can have a continuous time period selected as the object of data collection, then we can normalization our data. Evaluation with a variety of types, including efficiency, cost and interval, in these three properties, the bigger the better efficiency properties, costtype properties as small as possible, interval is a range of property values. In order to eliminate the results of different dimensions of evaluation, gives the following formula for calculating the standardized evaluation matrix, from this formula we can transform into a normalized matrix, represent the subscript set for efficiency indicators and cost index [5].REAL indicators standardized method. (1)Standardized method of interval numbers [6]. (2)Or (3). Innovation Competence Model and SolutionStep 1 Based on the current status of iron and steel enterprises technological innovation, innovation and petitiveness evaluation select 4, respectively:(1) Ratio of Ramp。 Ideal Solution。s iron and steel enterprises evaluation capacity for innovation system, so that China39。Competitiveness
