本文利用中国旧海关数据资料,分析了清中期东北与上海之间已有相当规模的大豆、棉布贸易及柞蚕丝转口贸易在近代的变动趋势,认为上海对东北土货贸易的市场地位相对下降,即近代东北对上海的贸易呈现出“去中心化”的现象。日本对大连、安东(今丹东)等港埠的掌控与商业扩张是导致东北疏离上海市场的重要原因,对近代中国的民族市场统一造成极大的负面影响。 Based on the data of China’s old customs, this paper analyzes the recent changes in the trade of soybean, cotton and tussah in the mid-Qing Dynasty between the northeast and Shanghai in the mid-Qing Dynasty. It considers that the market position of Shanghai in the trade of sorafeni is relatively lower, That is to say, the trade of northeast China with Shanghai in the modern times showed a phenomenon of “decentering”. Japan’s control and commercial expansion of ports and ports such as Dalian and Andong (now Dandong) are the important reasons for the northeast to alienate the Shanghai market and have a huge negative impact on the unification of ethnic markets in modern China.
