Classification Evaluation We 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? ?ij nmAa?? into a normalized matrix? ?ij nmBb??, ? ?1,2iIi?represent the subscript set for efficiency indicators and cost index [5]. ? ? ? ? ? ?1212,1 , 2 , , , 1 , 2 , , , , 1 , ,ijij LUij ijb j N i Nbb b j N i NN n N s N s s m?????? ?? ??? ???? ? ? ?

(3) Value ratio of new products = New product sales / corporate sales revenue. (4) The number of patents. Step 2 Use the calculation of the relative weight method on Single criterion of AHP to calculate the weight between each index.

(6) Step 6 Find the mean vector of the enterprise value evaluation vector with the largest relative closeness and draw conclusions. ,iiiidM i Ndd?????? (7) We can evaluate the innovation and petitiveness between these enterprises which we used, then obtained according to the start of the evaluation index of the relative weight by the Relative evaluation index weights. 4. Numerical examples On the global petitiveness ranking of steel sheet, the shortlisted 23 global steel prices and strong domestic steel panies, including Baosteel, Anshan Iron and Steel, Maanshan Steel, Wuhan Steel and Sha Steel[1],so in this article we select these five steel panies to carry out technological innovation petitiveness analysis. This article will link the 3year evaluation of the data because of the longterm technological innovation in large iron and steel enterprises. 2021 2021 innovation of the steel industry petitiveness index data, as shown in Table 1.
