Although the panel logit models verify the effects of the explanatory variables consistently with the theory, the prediction accuracy is not as good as that of neuro fuzzy. In addition to the better out-sample prediction accuracy, neuro fuzzy also provides a more detailed and complicated relationship among the variables through the rule base mid 3-dimension graphics, which could be used for further theory development or modification Overall, the banking crises ca be predictable; however, each country needs different forecasting model. The mapping between the forecasting model mid data set characteristics ca be further developed for the future research.

实证结果显示，虽然Panel Logit之固定效果与随机效果模型皆验证了过去理论上各变数对银行危机之影响方向，但整体而言，其预测准确度并不比类神经模糊好；而类神经模糊除了提供更准确的样本外预测之外，其所建构的规则库与3D图提供较以往更为细腻的变数关系，此关系可作为未来理论发展之基础；整体而言银行危机可以被有效的预测，然而单一国家的预测结果显示不同的国家适用不同的预测工具，没有一项工具能够适用於所有的国家；而资料集属性与预测工具之对应关系可作为未来之研究方向。
