| 摘 要： | 基于干散货二手船交易市场的波动性和交易风险一直备受船舶所有人、投资者、银行和造船厂的关注, 通过基于广义误差分布的自回归条件异方差（Generalized AutoRegressive Conditional Heteroskedasticity based on General Error Distribution, GARCH GED）模型计算得到二手船价波动率， 运用风险价值和损失期望值模型计算出一定置信水平下二手船交易的最大损失及损失的期望值.以5 年期的干散货好望角船二手船价进行实证分析，结果表明，上述方法能量化交易风险，有助于交易决策和风险控制.

| Abstract: | Because the volatility and risk of dry bulk secondhand ship transaction are always of concern to ship owners, investors, banks and shipyards, the price volatility of secondhand ship is calculated by the model of Generalized AutoRegressive Conditional Heteroskedasticity based on General Error Distribution(GARCH GED), and the maximum loss and expected shortfall of secondhand ship transaction in diverse probability levels are calculated by the value at risk model and the expected shortfall model. The price of 5 year dry bulk CAPESIZE secondhand ship is used for empirical study, which shows that the method can quantify the transaction risk, which is of benefit for decision making and risk control. |
