The author estimates the quantity of silver inflow during the last hundred years of the Ming dynasty based on literature review, and finds that there were almost 300 million taels of silver imported. Traditional beliefs are as follows. The vast quantity of imported silver supplemented the insufficient domestic production. This in turn led to the monetization of government finance and the economic prosperity of China’s southeast coast. The author argues instead that the advance of China towards a currency-based market economy led to the monetization of late Ming government finance. Further, international trade, not imported silver, supported the economic prosperity of China’s southeastern region. Finally, the imported silver was not the only solution to the lack of currency in circulation for the latter half of the Ming dynasty. For example, convertible paper money could be an alternative option. It is important to point out that the vast amount of imported silver might have adverse effects on the monetary policy and the monetary system of the Ming and Ching governments.
