Analysis Of Imported Iron Ores Price Fluctuation And Research Of Pricing Mechanism

China has become the world's largest producer and consumer of steel, and the steel industry has been a pillar industry. For China's economic importance is self-evident. Iron ore is the most basic and the largest demand of smelting materials for the steel industry. On the international market, iron ore trading modes in general are two: long-term contract mining and cash transactions (trade mine) .Since 2003, China has surpassed Japan to become the largest purchase of iron ore in the international market. At present, Chinese steel industry has already spent more than 50% of its iron ore imports. More than 90% of the new global iron ore consumption is for China, iron ore has been on a high degree of dependence on foreign ore. The international iron ore price has risen several times since 2004, which made the international iron ore price attracted more and more attention. From the international iron ore market in the current situation, the three international iron ore suppliers with their high degree of precision iron control of the international shipping, continue to raise the price. Chinese enterprises in the international market due to the lack of iron ore price passively accept a fait accompli, and create a major economic loss, which become the biggest victims in the price rising of iron ore. So the reasonable analysis of the reasons for the iron ore price fluctuations and making a reasonable forecast for the future price of iron ore are very necessary.The main works in this paper include:(1) Anal yze the supply and demand market and transportation market for iron ore fundamentally and expatiate the domestic and international iron ore trade;(2) Resear ch on the iron ore price fluctuation and its relevant factors, and carry on accurate quantitative analysis to these factors; (3) In term of inputting and exporting, establish the relation of nonlinearity between iron ore price and its influence factor with the simulation method of the differential simulation. Forecast the future price of iron ore with the Matlab.(4) In the time of analyzing array fluctuates on the foundation of the model, the constant and long memory of fluctuating to the price of iron ore has been examined.(5) On the basis of introducing the iron ore price fluctuations, analyze the international iron ore price formation mechanism and indicate the main view of the current negotiations in the international iron ore in the loss of the right to speak unfavorable situation, then put forward the corresponding countermeasures on how to deal with iron ore price fluctuations.
