学术界探讨的赊欠实为逐级赊欠。本研究提出“同级赊欠”概念。同级赊欠是在库存商品短缺的情况下，市场中的同行按照低于市场价格的价格调配货物、按照社会时间结款的赊欠交易。本研究以云北市明盛建材市场为同级赊欠的田野调研地点，发现市场中商家们在自利动机驱使下与同行建构社会关系、达成互利共赢，发生同级赊欠交易。互利共赢、社会关系是确保同级赊欠运行及再生产的社会机制。相较逐级赊欠而言，社会时间机制在同级赊欠中也发挥作用，但市场权力机制并未出现其中。

The credit discussed in academia is actually cascading credit. This study proposes the concept of "peer credit". Peer credit refers to credit transaction in which counterparts in a market with a shortage of goods in stock allocate goods at a price lower than the market price and settle payment according to the social time. Using the Ming Sheng Building Materials Market in Yunbei City as a field site for peer credit study, this paper finds that merchants in the market are driven by self- interest to construct relationships with their peers to achieve mutual benefits and win-win situations, resulting in peer credit transactions. Mutual benefits and social relationships are the social mechanisms that ensure the operation and reproduction of peer credit. In contrast to cascading credit, social time mechanisms play a role in peer credit, but market power mechanisms are not present.
