【摘要】:采用持續(xù)期依賴馬爾可夫轉(zhuǎn)換模型,通過Gibbs抽樣估計方法,對我國和美國股票市場的持續(xù)期依賴特點進行研究。研究表明我國股票市場在牛市和熊市中均具有較明顯的持續(xù)期依賴特征,其中牛市的持續(xù)期依賴特點強于熊市。美國股市在熊市中有明顯的持續(xù)期依賴特點,在牛市中幾乎不存在這種特點。造成這種差異的原因,主要是由于我國股市投機程度較高。
[Abstract]:By using duration dependent Markov transformation model and Gibbs sampling estimation method, the characteristics of duration dependence in Chinese and American stock markets are studied. The results show that Chinese stock market has obvious duration dependence characteristics in bull market and bear market, among which bull market is stronger than bear market. American stock market has obvious durative dependence characteristic in bear market, this kind of characteristic almost does not exist in bull market. The reason for this difference is mainly due to the high degree of speculation in China's stock market.
