中国城市化过程中的空间集聚与分散

Spatial Concentration and De-concentration in the Urbanization Process of China

城市是人类文明之花,城市化是世界范围的大趋势。现阶段,中国城市化正处于快速发展的时期,但可能存在城镇空间发展严重失控的危险。本文运用ROXY指数对1985-2005年期间中国城市化进程中的地域运动变化特征进行实证研究。结论显示,中国城市化空间循环运动过程基本上是由加速分散向减速分散,再向加速集聚转变的过程;而且中国八大经济区城市化进程中的空间集聚和扩散存在明显的区域差异。希望能为中国城市空间发展对策的制定提供一定的参考。

The city is a flower in hmnan civilization, and urbanization is an important development trend of the world. The pace of urbanization in China is very fast during the past decades. However the spatial sprawl of urbanization may be too fast. The paper uses the method of ROXY index to analyze the characteristics of urbanization regional movement in China during the past decades from 1985 to 2005. The results show that the spatial circulation process of China urbanization was changed from an accelerating deoncentration period to a decelerating de-concentration period and then to an accelerating de-concentration period, and with obvious spatial difference in 8 urban economic regions. This kind of analysis can provide some guidance to the urbanization development in China.
