“南、北满”是1905年日俄两国在东北争霸所造成的代表政治空间的新名词,以往的研究均是从政治史的角度阐述二者的来龙去脉。但若从经济史的视角看经济地域控制与南、北满政治区域的变动关系,“南、北满”政治区域的演化过程实与日本控制下的大连、安东两港与俄国控制下的海参崴港的经济腹地圈的争夺过程合二为一,两位一体,在日俄争霸东北的过程中,日本逐步通过市场渗透而把其势力从南满拓展到北满,1935年最终通过“三港三线”(大连港,南满铁路;安东港,安奉铁路;清津港,吉会铁路)完全控制了整个东北地区经济利益。此后,“南、北满”之词也逐渐淡出历史。 “South, North Man ” is the new term for the representative political space created by Japan and Russia in the hegemony of Northeast China in 1905. All the previous researches have elaborated the origin of the two from the angle of political history. However, from the perspective of economic history, the evolution of the political area under the control of the economic area and that of the southern and northern Manchurian regions has indeed been in line with the control of Russia under the control of Japan and the two ports of Dalian and Andong Under the economic hinterland of Vladivostok in the process of contention of the territory into one, two in one, Japan and Russia in the process of hegemony northeast, Japan gradually penetrate through the market to expand its forces from Nan Man to North Manchuria, finally passed in 1935 “Three-Port Three Lines ” (Dalian Port, South Manchurian Railway; Andong Port, An Feng Railway; Qingjin Port and Jijia Railway) completely controlled the economic interests of the entire northeast region. Since then, “South, North Man ” also gradually fade out the history of the word.
