营口开港后,日本资本作为殖民地经营的先驱进入中国东北,在资本输出、倾销剩余产品、攫取资源和高额利润的同时,铺垫了日本大陆扩张的基石。甲午战争后,日本凭借不平等条约,展开了经营东北殖民地的切实步骤,日本人流也纷纷涌进东北,在经济活动的幕布下,有些人充当日本军部的秘密情报员,还有一些人从事走私、贩毒等非法勾当,构成日本在东北推行大陆政策的社会基础。 After Yingkou opened its doors, Japanese capital, as a pioneer in colonial operations, entered northeast China and laid the cornerstone of the expansion of Japan’s continent while it exported capital, dumped surplus products, seized resources and generated high profits. After the Sino-Japanese War of 1894-1895, Japan, by virtue of the unequal treaties, started tangible steps in operating the northeast colony. As a result, Japan also flooded into the northeast. Under the curtain of economic activity, some served as secret intelligence agents for the Japanese military and others engaged in Smuggling and drug trafficking and other illegal activities constitute the social basis for Japan’s mainland policy in the Northeast.
