北宋陝西路發展與前代迥然不同，當時因著長期與西夏對峙，屯駐重兵，許多物資集中於該地，支援前線作戰，形成消費型態經濟。在這些輸運物資之中，絹帛有其特殊性，因為當地絲織業零星分佈，產量有限，不能滿足需求，必須仰賴外地供應，遂將四川、京師與本區連接成一個經濟網絡。其次，大批絹帛輦運至陝西境內，導致本地絹帛貿易發達，加上榷場及博馬貿易，使得絹帛流通範圍擴大至北宋西北境外地區。最後，輦送絹帛採用綱運方式，主要依賴遞鋪士卒，往來十分辛苦。

The Shensi region was the frontier of war with Shi-Shiah during Northern Sung dynasty, therefore, Shenshi had great demands for silk to meet the need of troops. The complicated situations of silk in Shensi will be discussed in this paper. These silk were used not only for furnishing army’s clothes, but also for exchanging food supply for army and trading horses with borderland nations. Since the amount of silk of Shensi was very limited, and it could not meet the great demands, the system of importing and delivering silk were then developed. For the sake of delivering silk, as a result, an economic network between SaShun and KaiFan was established.
