“门户开放”是19世纪末至20世纪前期美国的基本对华政策,在中国近现代史上占有不容忽视的一页。不少文章就“门户开放”政策对列强侵华是否起过抑制和延缓作用,即是否使中国避免被肢解、被瓜分产生过作用诸问题进行了多方考察,见仁见智,各执一端。本文试图从经济关系角度,阐述“门户开放”政策作用于对华关系过程中的利己主义实质,进而透视“门户开放”政策对中国社会经济的的影响。 “Open Door” is a basic U.S. policy toward the United States from the late 19th century to the early 20th century, occupying a page that can not be ignored in the modern history of China. Many articles have conducted a multi-party inspection on whether the policy of “opening up the door to the outside world” has served as a restraining and delaying effect on the invasion of China by the powers, that is, whether to allow China to avoid being dismembered and divided up and divided into two parts. This article attempts to elaborate from the perspective of economic relations, “open door” policy role in the process of relations with China, the nature of egoism, and then perspective “open door” policy on China’s social economy.
