After the World War II, the production of motorcycle gradually shifted from America and Europe to eastern Asia, in which place Japan has been a core. Asiatic states such as Vietnam, Indonesia and Taiwan devoted themselves into this tide, and Mainland China was no exception. Motorcycle industry in Mainland China, mainly responding military demand, was firstly found in the 1950s. With the changing of economic-political structure, private-owned corporations, both local and foreign, joined as competitors of public-owned corporations, and the market opened its door toward ordinary consumers. As a result, the production and sale of motorcycle increased rapidly, and in the mid-1990s, Mainland China has become the largest producer and market in around the world. To response the rapid development of both industry and market, its government enacted ¡§Industrial Policy of Motor-vehicle¡¨ in 1994 and 2004, in the hope to lead this industry toward a proper way. On the other hand, a lot of local government, ignoring central government¡¦s positive attitude, enacted ¡§Banning-motorcycle¡¨ one after another, which has driven motorcycle industry into the very moment of live and death. This thesis, taking Mainland China¡¦s industrial policy as the subject, theoretically based on state-central theory, combining ¡§Industrial Life Cycle Model¡¨, comparing Vietnam, Indonesia, Taiwan and Japan, analyzes industrial policy¡¦s important role and influence in the development of motorcycle industry to emphasize its intervention on motorcycle industry and market, and various tones played by the central and local governments.
