Since the end of the 20th century, almost all the financial crises around the world have been infectious cross‐border. As the global economy becomes more interconnected, cross‐border spillovers of financial crises become more rapid. It has become concerned and appeals scholars to study the cross‐border spillover mechanism of financial crisis and explore the effective measures to mitigate the external financial impact. This paper reviews the previous research of the spillover effect of international financial crisis, and points out the fields less involved in the current research, and puts forward some suggestions for future research direction and innovative perspective.
