本文对国债回购市场的利率数据在采用单位根和协整检验的基础上,通过分析国债回购利率走势和波动幅度的不同,将全部样本数据分成两个子样本,并在基于利率预期假说成立的基础上,利用单方程回归和向量自回归模型来检验收益率价差对未来利率变化的预测能力。结果发现.利率价差在两个子样本区间上都对未来的利率变化有较强的预测能力.且利率波动幅度越大,则利率价差对未来利率变化的预测能力越强;反之,则越弱。
本文對國債迴購市場的利率數據在採用單位根和協整檢驗的基礎上,通過分析國債迴購利率走勢和波動幅度的不同,將全部樣本數據分成兩箇子樣本,併在基于利率預期假說成立的基礎上,利用單方程迴歸和嚮量自迴歸模型來檢驗收益率價差對未來利率變化的預測能力。結果髮現.利率價差在兩箇子樣本區間上都對未來的利率變化有較彊的預測能力.且利率波動幅度越大,則利率價差對未來利率變化的預測能力越彊;反之,則越弱。

The paper, on the basis of testing government bond repo market's interest rate data with unit root and cointegration method, divides all sample data into two sub-samples by analyzing government bond repo interest rate trend and volatility range. Then, based on the existence of EMH, the paper utilizes single-equation regression and vector auto-regression model to test the predictive power of yield spread for the future interest rate change. The result shows that yield spread possesses good predictive power in the two sub samples and the power is higher in the more volatile first sub-sample. Thus, the yield spread in Chinese government bond repo market includes some useful information, reflects the expectation of market for the future interest rate change and may be used as a leading indicator to monitor the effect of conducting monetary policy by the Central Bank.
