In the new century, economic globalization is an obvious process which expanses with an unprecedented speed to all corners of the world and influences all aspects of the human life with irresistible force; its speed and great strength are much more than our imagination. It is not only to enable countries improve to a new level or descend into a new dilemma, but also causes profound changes and impact to the global economy of the new century and international relations.The 2008 global financial crisis, spreading from the virtual economy to the real economy and then quickly to all the economy realms, has had far-reaching impact to all the states.

The first part is introduction. The second part is the introduction of the global economic governance mechanism before the financial crisis. The third part introduces the impact of the crisis to the global economic governance mechanism; the fourth part, interoperates the development trends of G20, and highlights the developments of global economic governance under the interaction of power-system relationship.
