本文通过论述意大利成为文艺复兴发源地的五大因素，进而说明一个文化运动的兴起繁荣与经济基础，政治上的扶植，科技发展有着密切关系。其中关于当时一些罗马教皇及意大利城邦统治者在文艺复兴发源地形成中所起的积极作用的说法是我国以往的各种版本的外国文学史教科书所没有提到的。 This article discusses the five major factors that made Italy the birthplace of the Renaissance, and then shows that the rise and prosperity of a cultural movement is closely related to economic foundation, political support and development of science and technology. Among them, the statement about the positive role played by some Papal and Italian city-rulers in the birthplace of the Renaissance was not mentioned in previous versions of the foreign literary history textbooks in our country.
