摘要
采用2005年汇改后至2010年10月15日的日数据,研究了人民币兑美元名义汇率与我国股市收益间的线性与非线性因果关系。实证结论表明人民币兑美元名义汇率与我国股市收益间存在长期稳定的均衡关系,线性Granger因果关系检验表明存在人民币兑美元名义汇率到我国股市收益的单向因果关系,非线性Granger因果关系检验表明人民币兑美元名义汇率与我国股市收益间存在双向的非线性Granger因果关系,并且这种非线性因果关系很大程度上是由ARCH效应导致的。
The authors use the daily data from July 21th,2005 to October 15th,2010 to investigate the linear and nonlinear causality relationship between nominal RMB/USD exchange rate and China's stock market return.The results suggest that there's long-run steady equilibrium relationship between RMB/USD and stock return,and the linear Granger causality test reveals the uni-directional causality relationship from RMB/USD to stock return.While the nonlinear Granger causality test suggests the bi-directional causality relationships between RMB/USD and stock return,also the authors find that the nonlinear causality is mainly caused by the ARCH effects.
