摘　　要：在岸人民币汇率(简称:CNY)与离岸人民币无本金交割远期汇率(简称:NDF)的关系能反映人民币汇率形成机制改革的成效,同时对如何完善人民币汇率形成机制有借鉴意义。本文采用格兰杰因果检验、BEKK-MGARCH模型分别研究CNY与NDF的报酬溢出效应和波动溢出效应。结果表明,“811”汇率改革前后两个市场的关系发生了明显变化:从报酬溢出的角度来看,从不存在相互引导关系转变为出现双向的报酬溢出关系;从波动溢出的角度来看,汇率改革前CNY市场对NDF市场存在单向的波动溢出,而汇改后这种波动溢出减弱,并且出现反向的波动溢出。基于研究结论,提出针对性的政策建议:制定人民币汇率跟踪机制、放松在岸市场管制、建立在岸人民币NDF市场。The relationship between onshore RMB exchange rate(CNY)and offshore non-deliverable forward exchange rate(NDF)can reflect the effectiveness of the reform of RMB exchange rate formation mechanism,and is helpful to improve the RMB exchange rate formation mechanism.The paper uses Granger causality test and BEKK-MGARCH model to study the returns spillover effect and volatility spillover effect of CNY and NDF.The study finds that the relationship between the two markets has changed significantly before and after the“811”exchange rate reform:from the perspective of returns spillover,the relationship between the two markets has changed from no mutual guidance to a two-way returns spillover;from the perspective of volatility spillover,CNY market had one-way volatility spillover to offshore NDF market before the exchange rate reform,but after the exchange rate reform,this volatility spillover weakened and reversed.Based on the empirical results,the paper suggests such policy recommendations as:establishing RMB exchange rate tracking mechanism,relaxing onshore market control,and establishing onshore NDF market.
