Abstract: In the present china, the boom of the Policy ethics is closely linked with the establishment and development of socialist market economy. Market economy has fundamentally altered the production mode of traditional society, therefore threatens the survival of traditional virtue ethics and causes its marginalisation. However, it's partial to consider that Policy ethics is the product of modern society and the only form of market economy. Tracing the traditional origin of the culture of Policy ethics has both reference meaning and real value to promote national culture.

Key words: Policy Ethics, Courtesy, pre-Qin period, Chinese traditional culture
