摘要:This paper conducts an empirical analysis based on the balanced panel data of 18 emerging market economies between Q1, 2005 and Q3, 2017 to identify the influence factors of short-term international capital and discuss their time-varying characteristics. The system GMM model shows that short-term international capital is negatively correlated with the VIX (Volatility Index) and US real GDP growth rate, and is positively correlated with the appreciation of emerging markets’ currencies. The TVP-VAR model shows that short-term international capital has positive impulse response to its own changes, appearing “herd effect”, and has the largest impulse response to US GDP growth, VIX, US dollar appreciation and itself within two quarters, which are all consistent with the variability of itself. What’s more, the VIX exhibits obvious time-varying characteristics. The financial crisis expands the influence of VIX and the US GDP growth rate, and the first round of QE amplifies the influence of VIX.
