Abstract:  Against the background of social transformation in China, the construction of community service system in northwestern cities has its own special problems such as a single source of fund raising, excessive dependence on enterprises, lack of professionals and an overall low level. For a better and faster development of community service system in northwestern cities, we should draw lessons from community service practice at home and abroad and accumulate both the positive and the negative experiences in the field to carry out continuous exploration and innovation. Threeparty coordination, civic participation and the union of welfare and business are that three principles that the development of community service system in northwestern cities should hold on to.

Key words: society transformation, city community, community service system
