人民币汇率与股价联动关系的实证分析 陈蕾艳 The Empirical Analysis of the Relationship between RMB Exchange Rate and Stock Price Chen, Lei yan 摘 要 汇率和股票市场在一国的经济发展中扮演着重要的角色，汇率是货币的国际价格，汇率的变动反映货币国际购买力的变化，对国民经济产生巨大的影响；而股市价格指数是一个证券市场整体股价水平的反映，通常成为国民经济的“晴雨表”，能够灵敏地反映实体经济的细微变化。汇率和估价本来分属于外汇市场和证券市场两个不同的范畴，但随着人民币汇率弹性的加大和股市中股权分置改革的深化，汇率和股价的联动关系日趋明显，关于人民币汇率与股价的联动关系的研究越来越受到重视。 关于汇率与股价的联动关系，本文从理论和实证分析两方面论述了汇率变动对中国股市影响问题。首先，综述了国内外的学者关于这个课题的理论成果；在实证分析中，本文采用了国内外学者在分析此问题时普遍使用到的平稳性检验、协整方法以及Granger因果检验法。 本文选取了汇率改革以后602个工作日的人民币兑美元的汇率中间价（直接标价法），伤证综合指数，上证A、B股指数，深证综合指数，深证A、B股指数进行检验。结果表明：汇率与股价的联动关系是存在的，总体而言，人民币汇率与股价存在明显的负相关，且汇率对股价的影响大于股价对汇率的影响。另外，在本文的最后，列出了本文的不足以及进一步的研究方向。 关键字：汇率；股价；ADF检验；协整检验；Granger因果检验 Abstract Exchange rate and stock market play a very important role in a country’s economy development .Exchange rate reflects external value of a nation’s currency status and the rate’s change may result in tremendous influence on domestic economy.
