| 摘 要： | 利用X12季节调整法和H-P滤波法对2007年1月—2018年3月我国玉米价格时间序列进行分解,研究其波动规律。结果发现,玉米价格受季节因素影响较大,整体趋势为先上升后下降,并呈周期性波动。利用ARIMA模型预测玉米价格走势,发现短期内玉米价格会有小幅度的上升。

| Abstract: | The time series of maize price in China from January 2007 to March 2018 are decomposed by X12 seasonal adjustment method and H-P filtering method, and the fluctuation regularity of them is studied. The results show that the price of maize is greatly affected by seasonal factors, and the overall trend is first rising and then falling, with periodic fluctuations. The ARIMA model is used to predict the price trend of maize, and it is found that the price of maize will rise slightly in the short run. |
