在原有流动性风险研究的基础上，充分考虑股票市场异质性，对流动性指标数据进行了最大重复离散小波变换（MODWT），然后运用GARCH-VaR模型分别计算各尺度上的VaR值，并对其进行了有效性检验。通过对各尺度VaR值的统计结果进行分析，验证所投资市场资本规模对风险容纳能力的不同以及长期投资者与短期投资者面对的不同流动性压力。

Based on investigation to liquidity risk before, this paper focuses more on the heterogeneity of stock market.

The paper proves risk capacity varies with capital scale, and the various risk pressure long-term and short-term investors face.
