Li Hua, Yu Simin, Liu Li, Zhang Tao


In this paper, in order to study the influence about the loss in steel industry, Arcelor Mittal is taken as an example with the net profit being used to measure the operating results of an enterprise. By selecting the influence factors of net profit index, using the method of ordinary least squares and an empirical analysis of econometric software--EViews7.0, a non-linear model is constructed among gross margin, selling, general and administrative expenses, cash and cash equivalents: at the end of the year and the net profit. Steel enterprises around the world by controlling these factors may achieve higher profit. Some conclusions can be got through the empirical analysis, such as the cost of steel enterprises can be well controlled, and it provides a favorable decision for the development of steel enterprises around the world.
