一般认为,一国的外交是其国内政治的延伸。然而,有时一国的内政也往往成为他国外交的延续,内政与外交之间的影响是相互的。这在近现代的中国尤为明显。本文从这一视觉出发,从美国人的政治理念、战后美国在华的主要目标、美国对战后中国的认识等方面对战后国民党政府行宪的美国因素进行了分析。 It is generally believed that a country’s diplomacy is an extension of its domestic politics. However, sometimes the internal affairs of a country often become a continuation of the diplomacy of other countries, and the mutual influence between internal affairs and diplomacy is mutual. This is especially evident in modern China. Based on this vision, this article analyzes the American factors in the constitutional post-war Kuomintang government from the perspectives of the American political philosophy, the main objective of the United States in China after the war, and the United States’ understanding of the post-war China.
