Abstract:
In recent years,the sharp fluctuation of Allium fistulosum price has greatly affected both the main operators and consumers of Allium fistulosum.The annual wholesale price of Allium fistulosum were taken as the research object in 2011—2018.Firstly,the descriptive statistical analysis of the fluctuation trend of the national price of Allium fistulosum was carried out.Secondly,the census X-12 seasonal adjustment method and H-P filtering methodwere used to decompose the price of Allium fistulosum into trend,periodicity,seasonality and randomness.The results showed that the seasonal fluctuation characteristics of Allium fistulosum price were obvious,and the irregular fluctuation characteristics did not show a significant trend of growth or decline.The duration and fluctuation range of each price fluctuation cycle were different,and the influencing factors of different cycles were also different.
