高频交易对金融市场稳定性的影响分析
摘 要
本研究旨在探讨高频交易对金融市场稳定性的影响机制及其潜在风险。通过构建包含市场微观结构、投资者行为和信息传递的多维度分析框架，采用事件研究法和VAR模型对2015-2022年间中国A股市场的交易数据进行实证分析。研究发现，高频交易在提升市场流动性和价格发现效率的同时，也显著增加了市场波动性，特别是在极端市场条件下可能引发"闪电崩盘"。研究创新性地识别了高频交易对市场稳定性的非线性影响：当市场处于正常状态时，高频交易的正面效应占主导；但在市场压力时期，其负面效应会显著放大。此外，研究还揭示了信息不对称和算法同质化是导致高频交易加剧市场不稳定的关键因素。基于实证结果，本文提出了完善监管框架、建立熔断机制和加强算法透明度等政策建议。

Abstract
This study aims to explore the influence mechanism of HF on financial market stability and its potential risks. By constructing A multi-dimensional analysis fr amework including market microstructure, investor behavior and information transmission, the event research method and VAR model are used to conduct an empirical analysis of the trading data of China's A-share market from 2015 to 2022. The study found that while improving market liquidity and price discovery efficiency, HFT also significantly increases market volatility, especially in extreme market conditions that could trigger a "flash crash."The research innovatively identified the nonlinear effects of HFT on market stability: when the market is normal, the negative effects of market pressure. In addition, the research also reveals that information asymmetry and algorithm homogenization are the key factors that lead to the market instability. Based on the empirical results, this paper puts forward some policy suggestions, such as improving the regulatory fr amework, establishing the circuit breaker mechanism and strengthening the transparency of the algorithm.
