对外贸易与近代云南统一市场的形成及其空间结构

口岸开放与对外贸易的发展推动了近代云南市场格局的变化，从而大致在20世纪初全省统一市场形成。受口岸开放格局和对外贸易发展的影响，近代云南区域市场形成了蒙自—昆明、腾越—大理（下关）“双核”型空间结构。区域双核结构既是口岸开放—贸易发展的产物，又是近代云南三关贸易特征形成，特别是贸易地位形成的重要影响因素，还是近代云南经济发展不平衡的空间机制之一。

The relationship between foreign trade and the formation of a unified market in Yunnan province in early modern times and its dual core spatial structure

The opening of ports and the development of foreign trade promoted the change in the market pattern in Yunnan in early modern times, thus forming a unified market in Yunnan in the early 20th century. Under the influence of the new pattern of ports and the development of foreign trade, the early modern regional market in Yunnan formed a dual core spatial structure of Mengzi Kunming and Tengyue Dali (Xiaguan). This regional dual core structure was not only the product of port opening trade development, but also an important factor influencing the formation of the characteristics of Three Customs Trade in early modern Yunnan, especially the formation of its trade status. It was also one of the unbalanced spatial mechanisms of economic development in early modern Yunnan.
