Analysis on Social Network of World Trade Situation in 2000-2009
Through a social network analysis of the trade data in the period of 2000-2009, this paper studies the world trade web in the new century and the impact of the subprime mortgage crisis on it. A descriptive analysis shows that the world trade web was a disassortative network with a small ＂rich club＂, that though most countries established trade relationships with many partners, only a few of these connections were intense, and that as the result of the subprime mortgage crisis, the decline in the trade ties went before the shrinking in the trade strength. A core-periphery structure analysis reveals that the coreness of USA declined constantly and that of Japan, Germany, UK, and France ascended, especially after the crisis, and that the coreness of the BRICs reached twice as great as the level before the crisis.
