摘要
在构建市场信心指数和市场活跃指数的基础上,借助于GARCH-M模型对市场的信息变量与波动性的关系进行研究。除通常的一些研究结论外,还得到以下结果:两种信息变量对市场波动有绝对的影响;市场活跃指数对波动有非对称的影响效果;上海市场的市场信心指数无非对称性的影响,但深圳市场低迷的市场信心会引起市场更大的波动。
The paper constructs market confidence index and market activity index, and then analyzes the relations of these information variables and the volatility by dint of GARCH- M model. Besides the normal conclusions, we get a lot of other useful ones, such as: the two information variables have an absolute effect on the market; Market activity index has a character of asymmetric effect; the market confidence index of Shanghai doesn't have a asymmetric effect, but the sluggish confidence of Shenzhen market will magnify volatility.
