  南北差异是我国最重要的地区差异。南北凝聚是我国最重要的凝聚方向。秦岭淮河是我国划分南北的主要界线。秦岭淮河以北和秦岭淮河以南,自然景观和人文景观有显著差别。
  我国地貌西高东低,形成三大阶梯。在我国东西差异中,最突出的一条是东部比较发达,西部相对欠发达。我国是世界上社会经济发展不平衡程度最大的国家。东西之间差幅大,反差强。我国东西部社会经济的巨大差异是自然环境和社会环境叠加的结果。
  考虑南北差异,中国地区可以分为南方和北方地区;如果考虑东西差异,中国地区可以分为东部、中部和西部地区。如果同时考虑南北和东西差异,中国地区可以分为北方、南方和西部地区。如果考虑管理要素,中国地区的区域划分要尊重行政区域的完整性。
几种区域划分方案:
  第一层,将全国分为北方(东北和华北)、南方和西部等三大片(或四大片);其中,西部地区是将北方的西北地区、南方的西南地区集合在一起。
  第二层,将北方分为三个区域:东北地区、华北沿海和黄河中游地区;将南方分为三个区域:华东沿海、华南沿海和长江中游地区;将西部分成两个区域:西北和西南地区。
  第二层次的划分,也是参考中国东部、中部和西部三大地带的划分进行的。其中,将中国东部地区分为四大区域:东北地区(包括东部的辽宁、中部的吉林和黑龙江)、华北沿海、华东沿海和华南沿海地区;将中国中部地区分为两大区域:黄河中游和长江中游地区;将中国西部分为两大区域:西南和西北地区。
