Abstract:This paper uses high frequency data from Shenzhen Stock Market to conduct an empirical study of bid-ask spreads patterns and the associated determinants that affect bid-ask spreads by theory of stock market microstructure. To search for the characteristics of China's stock market microstructure, the models are formulated to test the factors that affect the bid-ask spreads patterns. The empirical study finds that there exists a “L" bid-ask spreads pattern in Shenzhen Stock Market, and the spread is relatively small. In addition, the factors that affect the bid-ask spreads include variance, price, and some trading time periods such as 1-hour after morning trading, 10-minute after afternoon trading and 20-minute before the market closes. These findings reflect some characteristics of China's stock market microstructure, they are not only helpful for us to understand the trading information and bid-ask spread patterns, but also very important for supervising market and re-adjusting trading policies.
Keywords:Stock Market Microstructure  Bid-ask Spread  Determinants
