【摘要】 货币政策对股票价格的影响是近年来经济学界和中央银行越来越关心的问题。自20世纪70年代以来,特别是近20年,发达国家和新兴国家的股票市场日益发展,股票市场在一国国内融资和国民经济中的地位和作用日益巨大,因而股票价格的波动必将对一国乃至全球经济产生重大的影响。近几年,我国股票市场迅猛发展,市场规模不断扩大,越来越多的居民投资于股市。自2005年以来,我国股票市场波动较大。上证指数在2005年6月达到998点的低点后,大幅上涨,2007年10月达到6124点的高点后大幅下挫,短短一年的时间,于2008年10月28日下跌至1664点,基本经历了一个完整的周期。在此期间,中央银行13次调整基准利率,22次调整存款准备金率,货币政策变动之频繁,前所未有。在股票价格和中央银行的货币政策之间究竟存在着什么样的关系?在以后的经济社会发展的过程中,中央银行将更多地使用货币政策工具直接或间接地影响和调控股票价格,因此,我们有必要深入研究货币政策对股票价格的影响。本文对于股票价格指标的选取采用的是沪深300指数,而不是上证指数,避免了指数失真可能导致分析结果的误差性；采用了最新的数据和较新的计量经济方法如向量自回归模型(Var)、ADF检验、协整检验、格兰杰因果检验、向量误差修正模型(VECM)、脉冲响应函数、方差分解等,对货币政策影响股票价格的机制进行了系统全面的分析,既有理论分析,又有实证分析,而且更侧重实证分析。包括：利率、货币供应量、信贷规模以及汇率对股票价格的影响。根据新指标和新数据得出的结论：利率、货币供应量和汇率与股价有长期协整关系,信贷规模与股价则没有；短期内利率对股价的影响是负的,而长期则是正的；货币供应量对股价的影响长、短期均为正的；汇率对股价的影响是负向的；各变量对股价波动的贡献度为：利率对股价的影响占8%,货币供应量占5%,汇率占4%。文章最后根据实证分析的结论提出了一些建议：中央银行可以通过货币政策调控股票价格；应加快发展股票市场,扩大股票市场的规模；加大对信贷资金的监管,防止违规入市以及防止短期内人民币大幅度升值。更多还原
