As a result, some utilitarian factors have gradually infiltrated into the current rural daily contacts, which leads to the unprecedented complexity and changeability of rural interpersonal relationship. On the basis of studying the changes of interpersonal relationship in the rural areas of Northwest China, this paper briefly analyzes the causes and logic of the formation of this change situation, so as to provide a theoretical and factual basis for people to correctly understand the interpersonal structure of rural areas in the northwest transition.
