北宋后期,政府实施向西北扩大辖区的积极边疆政策。面临诸多新的社会和民族问题,宋廷在开边拓土、扩大辖区、维护其新旧归附区的统治时,加强了对西北地区的防务和经营,并颁行了许多相关蕃部的法律法规,强调运用法律手段调整各族关系,治理边族地区的矛盾和纠纷,对于边地社会稳定和经济发展起了重要作用。 In the late Northern Song Dynasty, the government implemented an active frontier policy of expanding its jurisdiction to the northwest. In the face of many new social and ethnic issues, Song Tien stepped up defense and operation of the northwestern region while opening up territories and expanding its jurisdiction to maintain the rule of the old and new areas, and he has promulgated many relevant laws and regulations He emphasized that the use of legal means to adjust ethnic relations and control conflicts and disputes in the tribal areas has played an important role in social stability and economic development in the border areas.
