【摘要】：本文運(yùn)用GARCH(1,1)模型分析法定節(jié)假日因素對蔬菜價格波動的影響,研究結(jié)論將有利于蔬菜市場主體評估節(jié)假日期間價格波動風(fēng)險。研究結(jié)果表明,法定節(jié)假日期間,雖然蔬菜價格水平變化趨勢各異,但各類蔬菜品種的價格波動加劇,風(fēng)險明顯增加。蔬菜市場主體應(yīng)足夠重視法定節(jié)假日所引致的菜價波動加劇情況,以降低風(fēng)險帶來的損失。
[Abstract]:In this paper, GARCH (1 / 1) model is used to analyze the effect of the statutory holiday factors on the price fluctuation of vegetables. The conclusion of the study will be helpful for the main body of the vegetable market to evaluate the risk of price fluctuation during the holiday period. The results show that the price fluctuation of all kinds of vegetable varieties is intensified and the risk is obviously increased during the legal holidays, although the price level of vegetables varies with each other. The main body of the vegetable market should pay enough attention to the aggravation of the fluctuation of vegetable price caused by the statutory holidays in order to reduce the loss caused by the risk.
