In a network analysis, we analyzed the complex structure of cross-border capital flow across 65 countries from 2002 to 2018 to determine how patterns of capital flow in the global capital network affected economic growth. The results show that countries with large GDPs and offshore financial centers were major nodes with great influence on the global capital network. In addition, considerable growth was observed in the economies of neighboring countries that actively traded capital with the major nodes in the network. However, during the financial crisis, active cross-border trading became a channel of contagious insolvent capital, resulting in a sharp drop in the global economy.
