摘要 

《当幸福来敲门》是一部关于父子亲情，追求梦想，寻找幸福的经典励志电影，在主人公为实现自我梦想的过程中让读者充分体会到了实现梦想的艰辛。本文以城市空间为研究视角，从资本主义社会中美国黑人所处的社会处境来分析黑人美国梦的实现。在城市空间视域下，本论文从外在原因和内在原因对人物进行分析。介绍了黑人的变化：从奴隶身份到自由身份；从种植园时期到进入城市后的生活；以及自我意识的变化。研究发现，在种族歧视以及历史遗留问题下，黑人面临着各种社会歧视。因此，绝大多数黑人难以实现自己的美国梦。而克里斯通过自己的努力获得的成功只是极少数人的成功。同时，这个研究具有一定的现实意义。它激励着人们在社会中塑造自己的价值观，寻求自由和机会的平等。
