With the changing of international division pattern, the economy in East Asian Region has broken through the traditional “mode of wild goose travel” and formed a new type of East Asian production network, which has become an important part of the global production network. China, as the core of the production network in East Asia, has increased in trade in the region year after year. It is mainly embodied in importing a great deal of parts and components from the region and exporting finished products to such countries as USA, in EU, etc. outside the region after processing. China has been playing a part of intermediate hub in the “triangular trade” inside and outside East Asian Region. Although such typical trade characteristic improved the competitive power of the member countries in the production network of East Asian Region in a certain period of time, the impact of the American financial crisis on East Asian Region showed that the production network in East Asian Region was fragile to a certain degree.
