Abstract
The relation between the household electrical consumption and population for Chinese cities in 2006 has been investigated with the power law scaling form . It is found that the Chinese cities should be divided into three categories characterized by different scaling exponent . The first category, which includes the biggest and coastal cities of China, has the scaling exponent > 1. The second category, which includes mostly the cities in central China, has the scaling exponent ≈ 1. The third category, which consists of the cities in northwestern China, has the scaling exponent < 1 . Using a urban growth equation, different ways of city population evolution can be obtained for different . For < 1 , population evolutes always to a fixed point population from below or above depending on the initial population. For > 1, there is also a fixed point population . If the initial population (0) > , the population increases very fast with time and diverges within a finite time. If the initial population (0) < , the population decreases with time and collapse finally. The pattern of population evolution in a city is determined by its scaling exponent and initial population.
