| 摘要: | 全球化浪潮、科技進步與金融商品日趨複雜等原因，讓金融商品價格容易在短時間內發生大幅波動，也使得風險管理成為不可避免的議題。本文遂針對重大金融危機事件做出定義，稱之為「金融壓力事件」，以股市大跌作為「金融壓力事件」是否發生的判定標準，且分別針對6個月與3個月的兩種不同判定期間做出定義。再以利率、匯率、資產價格等變數，搭配羅吉斯迴歸模型、類神經網路模型與支援向量機，建立金融壓力事件預警模型，每日針對是否發生「金融壓力事件」進行預測。本研究以台灣加權股價指數實證，實證結果顯示，不論哪一種方法，判定期間為6個月的預測結果都優於判定期間為3個月；不論判定期間長短，都是支援向量機預測能力最好，其次為類神經網路模型，羅吉斯迴歸則較弱。
With globalization, new technology and more complicated financial instruments, the financial market become more volatile, making risk management an inevitable issue. In this paper, we define a major financial crisis event as a "financial stress event." It uses the stock market crash as a criterion for the occurrence of a "financial stress event," and define two different judgment periods of 6-months and 3-months respectively. Using the variables such as interest rate, exchange rate, and asset price, together with the Logistic Regression model, Artificial Neural Network model, and Support Vector Machine, a financial stress model was established to predict the occurrence of “financial stress events” everyday. By using Taiwan Capitalization Weighted Stock Index as empirical evidence, the result shows that regardless of the method, the predictability of 6-months judgment period is better than the 3-months period. Regardless of the length of the judgment period, Support Vector Machine has the highest predictability, followed by Artificial Neural Network model, and Logistic Regression is the weakest. |
