摘要
最近几年,ACD(autoregressive conditional duration)模型有了很多新的发展。本文将在介绍高频数据特点的基础上结合是市场微观结构的理论对ACD模型及其迄今为止模型的一些新的发展和ACD模型在中国的实证研究进行了较全面的总结,讨论了标准ACD模型以及ACD模型的一些扩展形式的性质和设定和现存的诊断检验方法,并提出了模型存在的问题和未来可能的研究方向。本文利用标准ACD、Log-ACDII、EXACD模型分析中国股票市场的高频交易数据。研究结果表明,中国股票市场中股票的交易久期存在集聚效应,而杠杆效应并不显著。
Recently, ACD (autoregressive conditional duration) model have many new developments. This paper will firstly introduce the characteristics of financiak high frequency data. Then it provides up-to-date survey of the main developments in ACD modeling, empirical studies in china, including the properties of the standard ACD and its extensions, exiting diag- nostic tests. And finally this paper point out the problem in using ACD model and identify possible directions for future research. This paper also uses Chinese stock market high frequency data in the standard ACD model, Log-ACDII model and EXACD model. The results present that transaction duration performs clustering effect but not obvious leverage effect in Chinese stock market.
