Using the MS-VAR model, we construct three financial risk early warning models of currency crisis, bank crisis and asset bubble crisis to describe the regional characteristics of financial risk change in recent years. The MSI (3) -type VAR (1) model divides the currency crisis, the banking crisis and the asset bubble crisis into "low risk", "moderate risk" and "high risk" state, the division of risk and the warning signal Issued a timing more in line with China's reality.
