台灣金融機構的系統風險-∆CoVaR、分量迴歸模型、與隨機優勢檢定的應用

Systemic Risk from Taiwan Financial Institutions based on the Applications of ∆CoVaR, Quantile Regression, and Stochastic Dominance Test

摘要


本文使用分量迴歸,∆CoVaR指標、以及隨機優勢檢定,來分析台灣2006-2016年金融機構、市場、及不同產業間系統風險的外溢效果。發現狀態變數在危機情境下的解釋力會比平常時強;非金控公司對市場的影響高過金控公司;保險公司對市場的影響高過銀行與證券公司;拔靴K-S統計量則指出金融業對傳產業的影響、明顯高於傳產業對金融業的影響。

並列摘要


Impacts of systemic risk on market and other industries from Taiwan financial institutions are investigated in this study. During 2006-2016, empirical results show that more variation can be explained by state variables given crisis scenarios in the quantile regression. Non-financial holding companies result in stronger contagion effect on the market than financial holding companies do, and insurance companies result in stronger contagion effect on the market than banks and security companies do according to ΔCoVaR. By the bootstrap Kolmogorov-Smirnov statistics and the stochastic dominance test, it can be found that the financial industry results in very significant systemic risk on the traditional industry, but the traditional industry affects the financial industry insignificantly.
