中文摘要: 本项目在目前三种重要的金融创新背景下:IPO制度改革、高频交易推广,以及算法交易的广泛应用,针对交易者的交易行为、投机倾向进行理论建模,刻画不同信息结构、技术水平的交易者行为的决策方程。并在此基础上,研究交易者行为导致市场流动性短缺的渠道,以及流动性危机蔓延放大机制的理论基础。在理论模型指导下,基于深交所2009-2013年的账户级别的高频交易数据,估计根据财富水平和账户性质进行区分的20类交易者的决策方程,以刻画限价委托簿整体上的动态演进,从而构建新的前瞻性的市场流动性指标体系。在此基础上,针对IPO首日、光大事件进行实证分析,刻画交易者跟风策略、探讨市场中流动性短缺而导致流动性危机(泡沫)的机制。此外,依据市场中多资产的协同关系刻画由于单资产的流动性短缺导致其他资产的交易者跟风行为,从而导致全市场流动性蔓延的机制。本项目并将评估不同交易者在危机中的决策,提供流动性危机的预警指标体系。

英文摘要: In the cases of three types of financial innovations, i.e., IPO reforms,high frequency trading,and the popularity of algorithm trading, this project models the trading behaviors of various types of the market participants with differential information and technological advantages.Then the contagion mechanism of the liquidity crisis is theoretically modelled.A full scale empirical study based on 2009-2013 account level transaction data provided by Shenzhen Stock Exchange is conducted to estimate the decision functions of the various types of accounts, which can be used to predict the dynamic evolution of the limit order book. A new measure of liquidity is proposed then and is used to investigate the relationship between the strategic trading of the market participants and the liquidity crisis in Guangda event or the liquidity bubbles in first day of IPOs. The contagion mechanism is investigated via the channel of the portfolio rebalancing incentive of the market participants. The project also investigates the roles played by the institutional investors and individual investors during the liquidity crisis.
