On the basis of an analysis of the present profile of automobile consumer credit in China,a discussion is done on the meaning of its development. This thesis introduces the development of the market of automobile consumer credit overseas, and finds out the reasons why overseas automobile consumer credit leads to the successful development of automobile industry. It also analyses the causes of the slump in the market of automobile consumer credit in the country in aspects of influential elements such as economy,policies,society,consumption norms and so on. It has a deep discussion on some obvious problems in this field. For example,the market of automobile consumer credit is of no scale; the prices of automobiles are high; taxes are heavy and expenses are too much; average residents still have low income and no definite balance between income and predicted expenses; there is no perfect social credit system and individual credit system; there is not enough awareness of credit among the public. Taking theories in the area of industrial economics into consideration,it proposes basic measures of promoting the development of consumer credit in China: building up a credited society,a perfect and sound personal credit system.With credit database as the platform,all parties will be able to share information,improve the credit database,relevant regulations and laws as well as a risk warning system,thus operation and management of the operating entities will be improved,the cost of the practice of consumer credit will be reduced; strengthen the innovation of present financial system,develop financial products corresponding to different groups of customers,improve services,perfect the mode of "bank+insurance+automobile agents",make full use of the interne,adopt the practice of turning credit into securities.
