Copper-salt Economy in the Formation and Changes of Early Southwest Frontier in China
Throughout ancient China,copper ore and well salt were the most advantageous bulk mineral resources in the southwest region,and their early development actually formed several copper-salt economic circles in the southwest region.The Ba-shu copper salt economic circle effectively promoted the formation of the early"Ba-shu Co-location"cultural pattern.After the Qin Dynasty merged with Ba-shu,it developed towards the southwestern border.The Han Dynasty opened up and managed the southwestern frontier,and the strong copper and salt economy of Shu provided strong support for it.In the southwestern frontier,there is also an obvious copper-salt economic circle,and within the circle are all the civilized developed areas of the southwestern frontier.After the Han Dynasty conquered the southwestern frontier,it effectively controlled the original copper-salt economic circle and further developed the copper-salt economy,providing important impetus for the first large-scale development of the Han Dynasty's southwestern frontier.The boundary of its mining power also basically formed the external boundary of the Han Dynasty's southwestern frontier.At the same time,the deep baptism of its copper-salt economy has basically become the cultural frontier of the southwestern region of China between the Eastern Jin,Sui,and Tang dynasties,laying a higher and more direct frontier civilization platform for the development of the new southwestern frontier.The spatial limit and cultural consolidation are the two layers of logic that formed the copper-salt economy in the early southwestern frontier of China,and the power contained in this logic is actually an undeniable factor in the process of Chinese civilization and national origin.
