總體而言，發展中國家的存貸利差要高於發達國家；第二部分：在總結前幾年利率改革包括市場化改革的基礎上，認為，迄今為止，我國利率市場化改革的程度總體上還比較低：同業拆借利率、貨幣市場債券回購利率、現券交易利率、外幣貸款利率、大額外幣存款利率等已完全市場化或基本市場化，人民幣存貸款利率的浮動區間已逐漸擴大，並已漸進的方式日益走向市場化；第三部分：在借鑒境外利率市場化過程中利率變動的經驗教訓的基礎上，認為在我國利率市場化的初期，利率應該有一小幅上揚的過程，但是其造成的市場波動應該不會太大；從改革的實際運作結果和中長期來看，外幣利率已經逐步的向國際利率水平靠攏；從短期來看，人民幣貸款利率總水平將趨于下降，部分貸款利率有可能上升，存款利率將會單邊上揚。The one is brought by meeting and overlapping of mixed and high level trough moving eastward cloud systems whose echo depth is about 12 km, and the horizontal distance is within 10 ~ 20km and the intensity is up to about 50dbz
