随着对用按揭贷款的方式购买房屋、车等大件商品的市场需求变失，我国商业银行推行越来越多的灵活的各种按揭贷款还款方式。针对商业银行目前主要推行的固定利率下的等额本息还款、等额本金还款、等额递增（递减）还款和“双周供”还款的现金流建模，并对这些模型进行久期和凸度测度，最后针对银行如何利用久期和凸度进行利率风险管理提出建议。

The market demand of using mortgage loans to buy house, car or other bulky products increases. Currently, domestic Commercial Banks provide varied flexible repayments of mortgage loans under a relatively fixed rate of interest. This essay analyzes the cash flow in mortgage loan repayment, and builds mathematical models of several major repayments under a relatively fixed rate of interest, such as repayments of equal amount, repayments of equal principal, repayments of equal segmentation unit increasing and decreasing and twice repayments within a month method. Then I measure and evaluate the models by Duration and Convexity methods. Lastly I give suggestions on how to use Duration and Convexity to manage the interest risks for the banks.
