Abstract: Through literature review, we found that there are abundant theoretical research results on the contagion of international financial crisis from multidisciplinary perspectives, with mainstream economics emphasizing the contagion mechanism based on economic fundamentals and financial trade linkages based on the rational-equilibrium framework; the newly developed narrative economics emphasizes the influence of irrational factors on the contagion of financial crisis, initially argues the causal relationship between "economic narrative" and financial crisis, and provides a new disciplinary perspective for financial crisis contagion; economic geography incorporates the concepts of "distance" and "space" into the framework of mainstream economics, providing a new method and means to verify the spatial spillover effect of financial crisis. Given that exogenous shocks, such as adjustments in the international economic and trade landscape, global climate change and geopolitical conflicts, have contributed to the continued rise in global financial risks and uncertainties, it is proposed to deepen the approach and direction of the research, including strengthening interdisciplinary synergistic research, proactively responding to the shocks of global uncertainty, and exploring an effective path for integrating economic development and financial security.
