基于综合城市化的城市群效率研究——我国三大城市群的实证比较

A Comparison with Concrete Evidences among Three Big Groups of Cities in China

中国传统意义上的城市化不是一种自生成长的城市化,而是在外部力量主导下的"粗放型城市化"。通过研究发现,在我国三大城市群,传统的城市化水平"虚高",很大程度上只是人口的"被城市化";综合城市化指数衡量的城市化水平更具内涵,反映了城市化的真实程度。通过对综合城市化效率的研究,我国三大城市群地区综合城市化效率总体有效性不足,尤其是大城市效率水平较低,而中小城市效率水平较高。通过对三大城市群比较发现,京津冀城市群综合效率水平最高,珠三角城市群综合效率水平最低;在效率变化上,京津冀和长三角城市群效率改善均优于珠三角城市群。

This paper constructs an index of comprehensive urbanization,with which,we evaluate the level of comprehensive urbanization to our country's three urban agglomerations.On this basis,we further research the efficiency of comprehensive urbanization.We consider that the traditional urbanization does not grow itself,but is a process of extensive urbanization dominant by external forces.Through empirical research on three urban agglomerations,we find the level of traditional urbanization is high with blankness,which is passive urbanization of population in large extent.We also find the level measured by index of comprehensive urbanization is better,which can reflect the real level of urbanization.Through research on efficiency of comprehensive urbanization,we find the effectiveness of comprehensive urbanization is shortage in three urban agglomerations,especially,the efficiency level is lower in big cities,but the middle and small cities are higher.Through comparison,we find that the comprehensive efficiency is highest in the Jing-Jin-Ji city group,and lowest in the Pearl River Delta city group.In the efficiency change,the Jing-Jin-Ji city group and the Yangtze River Delta city group are better than the Pearl River Delta city group.
