摘要：从1990年以来，文化全球化已经发展了20多年。在很长的一段时间里，美国的经济水平稳居世界之首，它先进的现代化状态给其他国家提供了很好的现代化发展经验。当现代化成为其他国家不可避免的选择时，美国大众文化自然显示除了它对其他国家人民极强的吸引力。正因如此，在文化全球化进程中，美国文化很大的影响了全世界，有消极影响，也有积极影响。

　　　本论文将对美国文化在文化全球化现象中，对世界造成的积极影响进行讨论和总结，从而发现美国文化所扮演的角色。美国文化推进了国际文化交流，普及了英语从而推进了国际交流。英语让人们开拓了视野也意识，加深了对世界的了解。美国文化自身如同一个模范，为世界文化交流提供了平台，让各种文化互相学习，取长补短，从而更加适应世界现代化的发展。美国力量而带来的文化传播是双向的，当美国文化疯狂传遍世界的同时，各国本土文化也具有了同样面对国际市场的机会。同时，一个国家的经济也是一国文化价值的体现，而市场在经济发展中无疑是最重要的因素。美国文化也改善了本土文化，让其能适应并拥有更大的市场，从而带动本国经济发展。美国文化也对一些社会带来了一些政治上的改变。
