1903年梁启超美国本土之行是他对美国社会政治、经济、文化等的全面考察之旅。其考察重点是美国政治制度,包括联邦制度。他对于联邦制度的认识富有现代性,显示出一个政治家非凡的洞察力,为同时代的中国政治精英所不及。此次考察也是他的一次思想转变,即弃卢梭民权主义,而尚波伦哈克、伯伦知理国家主义;弃革命,而重尚改良;弃民主共和,而重尚君主立宪;弃联邦制,而重尚单一制。 In 1903, Liang Qichao’s visit to the United States was his comprehensive tour of the politics, economy and culture of the United States. The study focuses on the American political system, including the federal system. His modern understanding of the federal system shows the extraordinary insight of a politician beyond the reach of contemporary Chinese political elites. The inspection was also one of his thought changes, that is, abandonment of Rousseau’s democracy, while Shangpolunhak and Burlem were in charge of nationalism; they renounced the revolution but emphasized reform; abandoned the democratic republic while emphasizing the constitutional monarchy; abandoned the federalism , While the weight is still single system.
