明代中前期,西南地区私茶贸易发展甚速,并最终取代官方茶马贸易。本文认为明代中前期西南地区的私茶贸易助长了明代官场腐败,败坏吏治;破坏明代边防战略;影响明朝财政等方面危害。我们在肯定私茶贸易积极作用时,还要重视私茶贸易所带来的消极影响,并加以适当引导和管理。 In the early Ming Dynasty, private tea trade in the southwest developed very rapidly and eventually replaced the official tea trade. This paper argues that the private tea trade in southwest China during the mid and early Ming dynasties contributed to the corruption of officialdom in the Ming Dynasty, the corruption of officialdom, the undermining of the border defense strategy in the Ming Dynasty and the harm to the Ming Dynasty finance. While affirming the positive role of private tea trade, we must attach importance to the negative impact of private tea trade and appropriately guide and manage it.
