【摘要】：目前中国的城市化进程已经进入关键发展时期,城市规模迅速扩张,但与此同时也衍生出很多城市问题,中国是否应该限制大城市的发展成为一个极具争议的话题。针对该问题,本文在包含异质性个体的城市内生性理论框架下,重点分析中国城市的最优城市规模和均衡城市规模的差异,并衡量差异带来的经济效率损失。实证结果表明:中国城市的均衡规模均超过其最优规模,但规模差异所带来的经济效率损失较小。从经济效率的角度考虑,在当前的发展阶段,中国应该继续鼓励大中小城市和小城镇协同发展。
[Abstract]:At present, China's urbanization process has entered a critical period of development, urban scale is expanding rapidly, but at the same time, there are many urban problems, whether China should limit the development of large cities has become a controversial topic. In view of this problem, this paper focuses on the analysis of the difference between the optimal and balanced urban size of Chinese cities under the framework of urban endogeneity theory, which includes heterogeneous individuals, and measures the economic efficiency loss caused by the differences. The empirical results show that the equilibrium scale of Chinese cities exceeds its optimal scale, but the economic efficiency loss caused by the difference of scale is relatively small. From the point of view of economic efficiency, China should continue to encourage the coordinated development of large, medium and small cities and towns at the present stage of development.
