中文摘要:

引入4因子仿射利率期限结构模型,并通过采样卡尔曼滤波方法解决非线性系统中的最优估计问题,对上海证券交易所国债的流动性溢价问题进行了研究。研究发现,上交所中长期国债存在流动性溢价现象,并且估计出国债的流动性溢价规模,与国外均值水平相比,国内溢价水平偏低,10年期国债的流动性溢价水平低于5年期和7年期国债。进一步考察国债流动性溢价的时变特征发现,上交所中长期国债存在新券溢价效应,流动性溢价随债券年限的增加而递减。针对以上特征,从债券市场交易机制与投资者行为等角度进行了分析,以期更深刻地认识中国债券市场,为合理定价和套利交易做出指导。

英文摘要:

A four-factor affine model was introduced. Using the model, the liquidity premium of treasury bonds in Shanghai stock exchange was studied. An issue of nonlinear system optimal estimation in this study was resolved by UKF method. The result indicates that the mid and long-term treasury bonds of Shanghai stock exchange have liquidity premium. The scale of liquidity premium is lower than foreign mar- kets, and liquidity premium of 10 year bonds is lower than 5 year bonds and 7year bonds. By exploring the dynamic characteristic of liquidity premium, the 'on the run' effect of the mid and long-term treasury bonds in Shanghai stock exchange was found, and the scale of liquidity premium decreases as age of bond increasing. Finally, the above characteristics was analysis from trading mechanism and investor behavior aspects in order to better understand Chinese bond market and guide asset pricing and arbitrage trading.
