摘要

The prices of rare earth products in China fluctuate periodically. In order to figure out the fluctuations rule, this paper chooses the monthly prices data of rare earths neodymium oxide and dysprosium oxide as samples from February in 2006 to December in 2017, uses the X12 seasonal adjust method and the H-P filter model to analyze the periodic fluctuations of their price empirically, and acquire the prices periodic fluctuations feature of rare earth products in this period. During test period, research shows prices of rare earth oxide products experienced two periods, the second trough of wave of two products both can be seen in the quarter 4th of 2012. In consideration of the huge fluctuation of rare earth products prices in 2011, there must be a long-term fluctuation period, in which the price of rare earth neodymium oxide has reached 57 months, and the price of dysprosium oxide has reached more than 65 months. As of December 2017, it has not yet fallen. Quotes, but the price of rare earth neodymium oxide appeared a short rise, and then entered the down channel.
