发布时间:2018-09-09 20:16
【摘要】:股票市场对经济发展有着非常重要的作用,可以为企业提供筹资和融资的功能。同时股票市场也被称之为宏观经济运行的先行指标,对宏观经济走势具有预测和解释的作用。波动率是用来衡量金融资产价格波动程度的重要指标,在期权定价、金融投资领域以及监管方面也具有非常重要的作用。研究发现,波动率具有尖峰肥尾性、集聚性、杠杠效应等特征。本文首先对波动率的特征进行描述之后,收集1999年12月至2015年12月的上证综指月度数据、深圳成指月度数据以及宏观经济指标(CPI、PPI、发电量EL、Shibor、M2、进出口额ⅣV)月度数据,并进行数据清洗和整理。使用Eviews8首先对各时间序列对数收益率数据进行描述性统计分析,发现各对数收益率时间序列均存在尖峰肥尾的特性;其次对各时间序列对数收益率曲线进行分析发现各序列具有波动集聚性;再进行平稳性检验、自相关性检验以及异方差性检验后,对各时间序列建立GARCH模型来对波动率进行分析。对波动率有一定的了解之后,首先对上证综指收益率时间序列和宏观经济指标收益率时间序列建立VAR模型,发现CPI和发电量波动与上证综指波动的趋势相同,M2和进出口额与上证综指波动的趋势相反,Shibor、PPI与上证综指波动的影响趋势不确定。最后使用深圳成指来进行验证分析,得出的结论一致。

At the same time, the stock market is also called the leading index of macroeconomic operation, which can predict and explain the macroeconomic trend.
