摘要股票市场是市场经济体系的重要组成部分，股票市场的有效性问题也成为衡量一国证券市场成熟与否的关键标志。20世纪90年代我国股票市场诞生发展以后，日益成为影响国民经济的重要因素。在其不断走向规范化的过程中，也暴露了许多问题，如信息传导机制低效、市场制度单一、上市公司治理不当、政府监管本质界定不当等，这些都影响了我国股票市场的效率问题。股票市场有效性的检验方法有许多种，本文通过单位根检验与资本资产定价模型来研究我国股票市场的特征，分析我国股票市场低效的原因，并依据实证分析的结论对提高我国股票市场有效性提出相应合理的对策。从实证分析结果可看出，我国股票市场基本达到弱式有效，有效性很弱。51034
