) Abstract: Steel is a special commodity; it’s an important strategic material
Each country attaches great importance to its price fluctuation, because the change will influence the economic development, even national security
Therefore, based on research of historic stage of steel price fluctuation, this article analyzed its distributive character by GARCH-t and GARCH-N models, showed that the model it’s price time series isn’t N distribution according to the conclusion that the stimulation based on t-distribution is better than N-distribution
