最优城市规模与特大城市户籍管制的自增强机制
Optimal city size and self-enhancement mechanism of Hukou regulation in megacities
摘要
Abstract
Strict Hukou regulation is often taken by megacities with over 5 million inhabitants to relieve its bearing pressure and control its size.While the truth is,the stricter household registration controlled,the more population it has.Based on the theory of optimal city size,this paper established a self-enhancement mechanism of Hukou Regulation in megacities and made a systematic analysis of its formation.It is found that though strict Hukou regulation has reduced the congestion cost of exclusive public goods,it does not influence the returns to scale of population growth,which gives rise to an increasing optimal city size obtained when marginal return of urban scale equals marginal congestion cost,a further expansion trend of urban population and ultimately a stricter Hukou regulation.The empirical analysis of the self-enhancement mechanism in 286 prefecture cities demonstrates that reinforced Hukou regulation nourishes big cities and megacities while undernourishes middle-sized and small cities,and thus the large-sized cities are more inclined to tighten its household registration policies.In addition,the reinforced Hukou regulation makes the inverted ' U'curve vertex between urban per capita income and population size shift to the right,elevates m optimal population size in egacities and further promotes the inflow of population.The self-enhancement mechanism has challenged the Hukou policy in megacities.Under the condition of intensive Hukou regulation,most megacities do not reach its optimal population size and tend to increase its population.Being caught in the vicious circle between strengthened Hukou regulation and expanding population,megacities have failed to control its population size by strict Hukou regulation.To get rid of the self-enbancement mechanism,it is advisable to lift household registration restriction and improve the non-exclusive public goods in middle-sized and small cities to absorb non-registered transferred households.关键词
