Physiographic macroregions of China
Physiographic macroregions of China is a term suggested by an American anthropologist G. William Skinner as a subdivision of China Proper into nine areas according to the drainage basins of the major rivers and other travel-constraining geomorphological features. They are distinct in terms of environment, economic resources, culture and more or less interdependent histories with often unsynchronized developmental macrocycles.  They were described in Skinner's landmark essays in The City in Late Imperial China.
Skinner and his school maintain that prior to the modernization, the transportation was largely constrained by the terrain and the physiographical macroregions are a close approximation for the socioeconomical macroregions of the 19th century China. These macroregions are defined by Skinner as follows.
- 10 Northeast China, 东北区
- 20 North China, 华北区
- 30 Northwest China 西北区
- 40 Upper Yangtze 长江上游区
- 50 Middle Yangtze 长江中游区
- 60 Lower Yangtze 长江下游区
- 70 Southeast Coast 东南沿海区 (approximately Fujian, eastern part of Guangdong, southern part of Zhejiang, and Taiwan)
- 80 Lingnan 岭南区, which may be translated as "South of Mountains". It includes the Southern coast and nearly coincides with the two entities: province of Guangdong and Guangxi autonomous region, together traditionally called "Two Guang provinces", or Liangguang. 
- 90 Yungui 云贵区; covers most of Yunnan Province and larger part of Guizhou Province and corresponds to the Yungui Plateau.
According to Skinner's analysis, the 20th century China excluding Inner Asia has 9 socioeconomic macroregions with cores not changed from the physiographic ones of the 19th century, but with changed territorial extents.
