本文嘗試從貨幣史的角度，分析十八世紀中國西睡內陸地區，不同政權勢力消長過程中，貨幣制度與貨幣政策的變化過程。文中首先具體整理十八世紀上半葉清代政府將西部邊睡納入管轄範圍以前，該區貨幣的歷史發展與中亞周邊地域的關聯性;其次分析十八世紀下半葉清廷在確立對新疆與西藏的統治過程中，一方面為穩定邊陸社會而沿用當地固有貨幣習慣，另方面為確立新政權的統治基礎對該區原有貨幣如何進行修正，並基於因俗而治以及強化主權的考慮下，清廷在這些地區最終提出什麼貨幣政策;最後檢討清廷新統治區域內所實施的貨幣體制，如何在社會經濟、幣值變化、財政考量等背景下，提出那些不同的方案與具體措施，從中又如何反映十八世紀清代的治邊政策。

The present essay analyzes changes in the currency system and policies applied by the eighteenth century Ch’ing court to the western interior regions of the empire. The essay first clarifies the currency history of the region, and its relationship to the bordering regions of Central Asia, prior to the advent of Ch’ing administration in the first half of the eighteenth century. It then analyzes the ways by which the Ch’ing court used monetary policy to encourage the acceptance of currency as a medium of exchange and affirm its political authority in the region. The essay ends with an investigation of the actual currency situation in the Ch’ing-administered regions of the West. It examines how the court, in light of socio-economic conditions, changing currency value, and financial considerations, dealt with the currency issue, and how these efforts reflect Ch’ing frontier policy in general.
