| 摘 要： 采用EGARCH模型,以铜、大豆及小麦三个主要的连续期货合约收益序列为样本的实证研究表明:利空消息对我国期货价格波动的影响,要大于利多消息对期货价格波动的影响。对300个期货交易者的问卷调查结果也表明:我国期货投资者普遍存在的“过度恐惧”心理,是造成利空消息对期货价格波动的影响大于利多消息对期货价格波动的影响的最为重要的原因。 |

| Abstract: This paper investigates the asymmetric impact of good news and bad news on the volatility on Chinese future markets by EGARCH for copper, soybean and wheat return series of consecutive futures contracts. The results show that bad news has greater impact on markets activities than good news. We inquired of 300 futures bargainers about this phenomenon and delivered questionnaire, which indicates that our local future investors have the mind of“over scare”universally, which is the most important reason to interpret why bad news has greater impact on markets activities than good news. At last we interpret the demonstration output in detail. |
