It is of great significance to strengthen the construction of the mainstream ideology in ethnic regions of China to promote our national unity,progress and shared prosperity. In the new situation,such factors as the relatively poor economic development,the cultural diversity,different values and the activities of the splittists have posed serious challenges to the construction of the mainstream ideology in such regions of China. Therefore,the current approaches to the quickened construction of the mainstream ideology include the following:it is necessary to have Marxism as the theoretical foundation,to develop the local economy quickly,to cultivate the diversity of ethnic cultures and the community consciousness of the Chinese nation,and to promote the publicity of good things through the mass media.
