Abstract
In order to analyze the fluctuation regulation of garlic price from a large number of garlic prices data, this paper makes an in-depth analysis of the garlic price data by using the HP filtering analysis method. Firstly analyzing the seasonal effect on garlic price volatility using CensusX12 seasonal adjustment method; secondly, the monthly data of garlic price in Shandong garlic wholesale market from January 2010 to December 2017 was decomposed by HP filtering. So the original sequence, the long-term trend sequence, and the cyclic variation sequence were obtained after the garlic price season was adjusted. Since January 2010, the fluctuation of garlic monthly prices can be divided into 5 cycles. After sorting out the regulation of garlic price and consulting a lot of data, it is concluded that the price of garlic is affected by planting area and natural conditions, and it is easy to cause market speculation and blindly follow suit.
