国际贸易网络上经济危机传播的仿真分析与研究
Dynamic evolution of crisis spreading and its spatial features on international trading network
摘要
Abstract
To understand the dynamic evolution of economic crisis and reveal its mechanism based on macroeconomic system,this paper used international trade data provided from World Trade Organization to build an international trading of weighted and directed network by complex network theory.It used a simple model of cascading crisis to simulate numerically an economic crisis,the results revealed that the GDP and tradevolumn might beth have significant influent on the avalanche size of the spreading,but not strong positive correlation.Then,it utilized target selection strategies to remove edges in ITN,the data showed that the economic interdependence between countries could significantly affect the convergence behavior of spreading on ITN.Furthermore,statistical analysis showed that the spatial features had identified within dynamic evolution,which suggested those countries from specially regions were vulnerable to crisis spreading.The findings in this study are helpful to deeply understand the evolution of crisis spreading and against to the emergence of cascading failures in economic system.关键词
