吐鲁番地区自公元640年建立西州后,即从平民中产生了一个新兴阶层,其基础和鲜明特色即多重身份的相互交叉。他们利用契约成为土地的合法占有者,利用高利贷盘剥均田百姓,利用廉价劳动力扩大生产,利用副业经济拓宽财富空间。租佃和高利贷是该阶层的基本经济生活形态,土地+副业+高利贷+中下层军官是其身份特征构成的四大组成部分。 Since the establishment of Xizhou in Turpan Prefecture in 640 AD, a new class has emerged from among civilians. Its foundation and distinctive feature are the multiple identities that cross each other. They use the contract to become the legal owner of the land, exploit the high-interest loans to exploit the average people, use cheap labor to expand production and use the sideline economy to expand the wealth space. Tenancy and usury are the basic forms of economic life for this class. Land + Sideline + Usury + Middle-lower-level officers constitute the four major components of their identity.
