Abstract

As an inherent part of Chinese indigenous legal tradition, dian originated from customary practices and was gradually incorporated into the national legal framework, reflecting a distinctive historical evolution, structural composition, and value orientation. Historically, dian evolved from a simple customary transaction into a formalized legal institution. It first took shape during the Tang Dynasty and matured through the Ming and Qing Dynasties. Structurally, long-term practice produced unique concepts and rules that embodied the dual nature of both usufructuary and security rights. In terms of value, dian was not merely an economic transaction tool but also reflected ethical norms and pragmatic wisdom of traditional society. It played a vital role in protecting the interests of the mortgagor, promoting circulation of land, and alleviating financial shortages. In the Civil Code era, the value of dian lies particularly in its ability to reconcile individual interests with social needs and to enhance the efficiency of property utilization.
