宋錢의 外流가 日本 貨幣經濟에 끼친 영향

Abstract

From the mid-8th century, Arabian merchants launched a new shipping routes between East and West. This made brisk maritime trade in the east asia. Not only the record, the excavation of the Shinan ship made the trade volume and trade item at that time public. On the study on the history of trade between 10th and 13th century, we must consider not only the literature records but the results of archaeological excavations. The history scholars have paid attention to the coin[宋錢] of the Song dynasty as a traded item. The coin, that casted mostly in the northern Song dynasty, was used as principal means of payment in China. Also the coin was outflowed overeseas by international trades with neighboring countries, and used to play a role as a currency in some foreign countries. In the inflow of the coin of the Song dynasty, Japan enforced land tax[地租] that changed the rule from using commodity money[實物地租] to using coin]貨幣地租] for the tax payment. Japan casted Wadōkaichin[和同開珍] in the 8th ceuntury, and enforced using the coin for tax payment. It means the Japanese tax payment system changed from using commodity money to using coin for tax payment. But the change was failed to reach to the monetary economy system until the 12th century, because the inflow of the Song’s coin was not enough. Since 12th century, as the Song’s coin flowed into Japan in large[great] quantities, and it allowed Japan monetary economy system to develop. And then, the rule that using coin for land tax payment spread nationwide. As the inflow of the Song’s coin in large quantities and spreading the circulation of the Song’s coin, Chinese coin, especially the Song’s coin played a major rule in the change of feudal tax payment system.
