文章通过对乾隆初年滇省代京铸钱之具体情况的考察,认为滇省代京铸钱是清政府为扭转铸钱严重亏损而采取的一项铸币政策。但滇省代京铸钱较之京局直接鼓铸反而增加了铸钱成本。实行滇省代京铸钱后,清政府铸钱开始盈利,但这并非滇省代京铸钱所致,而是清政府对云南铜矿实行垄断经营、压低铜价,即钱局使用滇铜鼓铸的结果。实际上,在使用滇铜为原料的前提下,京局直接鼓铸较之滇省代京铸钱更能节省成本,这是清政府停止滇省代京铸钱的基本原因。同时也说明清政府于乾隆初年实行滇省代京铸钱存在着决策性失误。 Through the investigation of the specific circumstances of Qianlong donating money on behalf of Beijing in the early years of Qianlong, the article holds that the money-making of Yunnan Province on behalf of Beijing is a sequestration policy adopted by the Qing government to reverse the serious loss of money. However, on behalf of Beijing Municipality, Yunnan Province, direct money casting instead of direct drumming increased the cost of casting money. After the implementation of Yunnan Provincial Government to save money on behalf of Beijing, the Qing government started to make money profitably, but this was not caused by money casting in Yunnan on behalf of Yunnan Province. Instead, the Qing government imposed a monopoly on Yunnan Copper Mine and pushed down the price of copper, that is, the result of. In fact, under the premise of using Yunnan Copper as raw material, the Bureau of Direct Drumming can save costs more than the casting of money on behalf of Beijing in Yunnan Province, which is the basic reason why the Qing government stopped casting money on behalf of Beijing in Yunnan Province. At the same time, it also shows that the Qing government made a mistake in making money on behalf of Beijing in the early years of Qianlong.
