摘要: 选取2011年至2015年上海期货交易所铜期货价格指数日内每5分钟高频数据,建立VAR模型,分析沪铜期货价格长期的波动及其影响.从描述性统计量分析,沪铜期货价格高频波动率具有尖峰后尾的特征|格兰杰因果检验显示:资金流量和沪铜期货价格波动具有双向因果关系|脉冲响应函数和方差分解表明:沪铜期货价格波动具有长记忆性,成交量对沪铜期货价格具有较强的正向效应,持仓量对沪铜期货价格具有较弱的负向效应.

关键词: 沪铜期货序列, 高频波动率, 分解

Abstract: Based on the high frequency data of copper future price index every 5 minutes in Shanghai Futures Exchange from 2011 to 2015, this paper establishes VAR Model,and analyzes the long-term fluctuation and its influence. Through analysis of the descriptive statistics, the high frequency fluctuation rate of Shanghai copper futures has the characteristics of spikes| Granger causality test shows that the flow of funds and copper futures prices have a two-way causal relationship. Impulse response function and variance decomposition show that copper futures price fluctuations have long memory, and volume has a strong positive effect on the Shanghai copper futures prices. The amount of open interest has a weak negative effect.

Key words: Shanghai copper futures prices, high frequency fluctuation, VAR model
