中国股票市场订单配售的实证研究

Empirical regularities of order placement in the Chinese stock market

Gao-Feng Gu, Wei Chen, Wei-Xing Zhou

摘要:

本文利用深圳证券交易所23只股票的超高频交易数据,对集合竞价、冷静期和连续竞价下的下单行为进行了实证研究。三个时间段的相对对数价格相对于参考价格的分布在定性上是相同的,但在定量上存在差异。买卖双方之间、帐内订单与帐外订单之间的下单行为是不对称的。此外,连续拍卖中相对价格的条件分布与买卖价差和波动率无关。这些发现对于建立基于订单流的中国股票微观行为模型具有重要意义。

英文摘要:

Using ultra-high-frequency data extracted from the order flows of 23 stocks traded on the Shenzhen Stock Exchange, we study the empirical regularities of order placement in the opening call auction, cool period and continuous auction. The distributions of relative logarithmic prices against reference prices in the three time periods are qualitatively the same with quantitative discrepancies. The order placement behavior is asymmetric between buyers and sellers and between the inside-the-book orders and outside-the-book orders. In addition, the conditional distributions of relative prices in the continuous auction are independent of the bid-ask spread and volatility. These findings are crucial to build an empirical behavioral microscopic model based on order flows for Chinese stocks.
