雍正皇帝为稳定商品市场的银钱比价,对铜钱制度深刻反思后进行了全面改革,至乾隆时期,改革后的铸钱成本长期保持在铜钱千文含银一两以下, 成本较低。而同一时期商品货币流通领域铜钱对纹银的兑换却低于一两,钱价高昂,钱价与钱值相悖。形成这个问题的根本原因,在于清政府对铜斤实行垄断经营、压低价格。基于清政府对鼓铸用锎垄断价格而形成的铸钱成本,并不能真正体现钱文的价值含量。铸钱成本的高低应取决于商品市场铜铅价格的高低。乾隆时期钱价高昂,正是当时商品市场铜价昂贵的曲折反映。 In order to stabilize the monetary price of the commodity market, the emperor Yongzheng conducted a comprehensive reform after profound reflection on the system of the copper money. By the time of the Qianlong Era, the cost of reforming the money for casting money remained below the level of one to two yuan of copper and thousands of silver coins at a relatively low cost. In the same period, however, the exchange rate of copper coins to grain silver in the commodity currency circulation area was lower than one or two. The price of money is high, and the price of money and the value of money run counter to each other. The fundamental reason for the formation of this problem lies in the fact that the Qing government monopolizes copper prices and lowers prices. Based on the money cast by the Qing government for monopolizing the prices of drums and castings, it does not really reflect the value of money. The level of the cost of casting money should depend on the level of copper and copper in the commodity market. Qianlong period, high prices, it was the twists and turns reflected in the commodity market, copper prices expensive.
