The interest rate liberalization reform is an inevitable choice under the general trend of economic globalization in the world. Mean while, interest rate liberalization is indispensable for Chinese economic development and financial stabilization. The interest rate liberalization reform should follow a certain principles and satisfy a certain require ments, otherwise the financial order will be in a state of chaos and the negative influence on economy will appear. The interest rate liberaliza tion reform needs a good economic environment and a series of relative reforms.展开更多

This Paper gives the relationship between interest rate and exchange rate: as a result of interest rate dropping, exchange rate is in great turbulence,whose fluctuation range relates to some coefficients.展开更多

The results show that the 3 models are almost equivalent in estimating interbank term structure of interest rates. Within the term to maturities between 0 and 7 years, the gap of the absolute errors of the 3 models between in-sample and out-of-sample is smRller than 0.2 Yuan, and the absolute values of the in-sample and out-of-sample errors are smaller than 0. 1 Yuan, so the estimation is credible. Within the term to maturities between 7 and 20 years, the gap of the absolute errors of the 3 models between in-sample and out-of-sample is larger than 0.4 Yuan, and the absolute values of the in-sample and out-of-sample errors are larger than 1.0 Yuan, so the estimation is incredible.展开更多

The interest rate liberalization reform should follow a certain principles and satisfy a certain require ments, otherwise the financial order will be in a state of chaos and the negative influence on economy will appear.
