《天盛改旧新定律令·取闲地门》,专门规定西夏荒地产权问题。通过比较西夏与唐宋荒地产权制度的相关问题,如土地产权的类型、耕种荒田的资格与义务、新耕者与荒地原主的土地产权关系等,并比较分析唐宋、西夏土地买卖契约文书,作者认为,西夏荒地产权制度不仅反映了西夏一朝土地私有制的发展状况,更是唐代均田制瓦解以来土地私有化在西北地区的历史继承。 “Tiansheng changed the old law to make the old law · take leisure to the door,” specifically the issue of property rights in Western Xia wasteland. By comparing the problems of the land property right system in the Western Xia Dynasty and the Tang Dynasty and the Song Dynasty, such as the type of land property rights, the qualifications and obligations of cultivating the barren land, the relationship between the landownership and the landownership of the original landowners, The author believes that the system of property rights of the wasteland in Xixia not only reflects the development of private ownership of land in the Western Xia Dynasty, but also the historical succession of privatization of land in the Northwest China since the collapse of the uniform land system in the Tang Dynasty.
