“清之盐法,大率因明制而损益之。”①食盐运销沿袭明代的专商引岸制,即“签商认引,划界行销,按引征课”。②也就是商人必须到指定的盐场买盐,然后到指定的引地销售,一旦越界,即以私论。清代内地盐区共分十一区,而两淮盐场最大,销区最广,包括江苏、安徽、江西、湖北、湖南、河南六省的绝大部分地区。 “Salt of the Qing Dynasty, the rate of loss due to the system of profit and loss.” ① salt distribution followed the Ming Dynasty’s quoted bank system, that is, “to attract business, demarcation and marketing, according to levy class”. ② That is, the merchant must buy salt from the designated saltworks and then sell it to the designated place of origin. The Qinghai Salt Lake area is divided into eleven districts, while the two Huai salt fields are the largest with the largest sales areas, covering most of the six provinces of Jiangsu, Anhui, Jiangxi, Hubei, Hunan and Henan.
