为了研究我国钢铁期货市场的波动情况,本文运用 SV 类模型对其波动特征进行了分析比较。结果表明:我国钢铁期货波动具有较高的持续性和波动集聚性,存在明显的尖峰厚尾现象,可以采用厚尾 SV 模型对我国钢铁期货进行分析,ASV 模型能够很好地拟合钢铁期货波动过程中存在的持续性和非对称性特征;利用随机波动模型求出的波动序列可以较好地计算 VaR值;钢铁期货下跌信息所引发的波动,比价格上涨信息引发的波动更大;为平抑钢铁价格波动的影响,建议加强钢铁市场监测预警,加强政府对钢铁价格的宏观调控,完善钢铁市场体系建设,积极推行钢铁产业良好发展。
為瞭研究我國鋼鐵期貨市場的波動情況,本文運用 SV 類模型對其波動特徵進行瞭分析比較。結果錶明:我國鋼鐵期貨波動具有較高的持續性和波動集聚性,存在明顯的尖峰厚尾現象,可以採用厚尾 SV 模型對我國鋼鐵期貨進行分析,ASV 模型能夠很好地擬閤鋼鐵期貨波動過程中存在的持續性和非對稱性特徵;利用隨機波動模型求齣的波動序列可以較好地計算 VaR值;鋼鐵期貨下跌信息所引髮的波動,比價格上漲信息引髮的波動更大;為平抑鋼鐵價格波動的影響,建議加彊鋼鐵市場鑑測預警,加彊政府對鋼鐵價格的宏觀調控,完善鋼鐵市場體繫建設,積極推行鋼鐵產業良好髮展。

To study the fluctuations of China's steel futures market,we analyze the features of it by using SV models in this pa-per.Results show that prices of steel futures volatility have continuousness and clustering features.The SV-T model can be used to analyze the heavy tailed distribution.The ASV model can well describe the continuousness and"leverage"effect in the fluctua-tion of China's steel futures.The value of VaR can be calculated by stochastic volatility model and the sequence of volatility. Greater volatility can be caused by the declining of the price than the information of rising.To stabilize the fluctuations of steel price,it’s proposed to strengthen the monitoring and forecasting in the market of steel,strengthen the government's macro-con-trol on steel prices,improve the market system and promote the development of steel industry.
