Abstract: The interest rate reflects the supply and demand relationship of capital market. It also has an important impact on economic growth, the operation of real enterprises, financial products pricing and policy regulation. The fluctuation characteristics of interest rate has been a research focus in both academic area and market area. From the perspective of system management, this paper makes a deep research on various factors which have important impact on interest rate in both money supply and demand system and systematically sorts out theoretical basis of interest rate decision from both macro and micro aspects. The return of 10-year CDB bond is selected as the proxy index of the market-oriented long-term interest rate. Based on the methodology of TEI@I, the EMD model is used to decompose the sequence of interest rate. The results show that, the interest rate has multi-scale features, and each component has different fluctuation characteristics. The long-term and middle long-term trends are mainly affected by the opening policy of Chinese financial markets. The low-frequency cycle is mainly affected by the factors of capital demand side, while the high-frequency cycle is mainly affected by the supply side. Further, the over-expected random disturbances are mostly accompanied by the impact of unexpected events.
