摘要
If the Group of Seven （G7） nations, established in 1975, was a global .governance institution guiding world economic development, then the Group of 20 （G20） nations, which now includes emerging economies, is a global governance institution guiding the world＇s response to the global financial crisis since 2008.
The G20 which includes emerging economies has been playing a key role in guiding the world's response to the global financial crisis and tends to become the "main forum for global economic cooperation",This move reflects a shift in the center of gravity of global economic power and may further influence the strategies of the various major powers in the world.
