| 10. | At last , we continue to analyze the influence which the macroeconomic growth rate has on the volatility of the stock returns . we make the macroeconomic growth rate as an exogenous variable to add to the above iterated weighted volatility model . from the above analysis , we can draw a conclusion that the volatility of the stock returns of chinese stock markets will strengthen in economic expansion period and weaken in economic recession period
在此分析前提下，继续深入分析宏观经济增长率对股票市场收益率波动的影响，将宏观经济增长率作为外生杠杆变量加入到上面的迭代加权最小二乘法的条件波动率模型中，结论是我国股票市场收益在经济扩张期波动性减弱，而在衰退期波动性增强。 |
