城市化形成及演进机制的比较

A Compare between the Formation and the Evolution Mechanisms of Urbanization

城市化的形成机制主要包括城市化的动力机制、实现机制和推动机制，其中动力机制部分从时间角度分析产业结构演变对城市化发展的驱动原理，实现机制部分从空间角度分析城市化得以实现的经济原理，推动机制部分则从市场和制度入手分析推动城市化发展的经济机理。三种机制的综合作用，促进了城市化的不断推进。

The forming mechanism of urbanization includes three parts which are the dynamical mechanism, the completive mechanism, and the impellent mechanism of urbanization. The dynamical mechanism referring to how the evolvement of industrial structure works on the development of urbanization from the angle of time; the completive mechanism analyses the economic principle of the realization of urbanization from the angle of space; and the third one involving how the market and institution affects the development of urbanization. The integrated effect of these three mechanisms promotes the continuous development of urbanization.
