摘　　要：在已有的高频时间序列模型的基础上,基于异质市场假说理论,构建了HAR-BACD-V模型.通过实证分析以探询在异质市场环境下不同交易频率投资者的交易行为对股市即时波动的贡献程度以及交易量对交易持续期、金融产品收益率和波动性的影响.研究结果进一步证实了我国股票市场的异质性,不同交易频率投资者的交易行为对股市波动的影响程度是不同的,并且发现交易量对交易持续期、收益率及波动性都存在不同程度的影响.On the basis of pre-existing high-frequency time series model and the Heterogeneous Market Hypothesis, this paper constructed the HAR-BACD-V model. Through the empirical analysis to probe into whether different trading frequency investors＇ trade behavior may have different contribution degree to instantaneous stock market fluctuations and volume may affect trading duration, financial product yields and volatility or not. The empirical results furtherly confirmed the heterogeneity of Chinese stock market, meanwhile, different trading frequency investors＇ trade behavior have different contributors to stock volatility, and found trading volume also have different influence on trading duration, returns and volatility.
