摘要
合理的"等级—规模"分布层级结构,是城市层级体系优化的必要条件。根据我国城市常住人口人数,利用"等级—规模"法则检验和核密度估计,并基于空间经济学框架,建立劳动力区位选择模型,且进行数值模拟,结果发现:我国城市层级结构与幂律为1对应的金字塔结构存在差异,户籍制度阻碍了劳动力自由流动,使城市规模分布偏离了帕累托最优。户籍改革有助于优化我国城市层级体系。优化城市层级体系,应该成为当前新型城镇化与城市群、都市圈建设的一致目标。
A rational hierarchical distribution structure by rank-size is indispensable for the optimization of China's urban hierarchy.On the basis of the number of permanent urban residents,using the rank-size rule test and core density estimation within the framework of spatial economics,we set up an employment location choice model and conducted numerical simulations.Our findings show that the structure of China's urban hierarchy is different from the pyramid structure of Zipf's law.The household registration system impedes free labor mobility and city size distribution deviates from Pareto optimality.Household registration reform would be conducive to the optimization of urban hierarchy.Optimizing this system should become a consistent objective in the construction of new-style urbanization,city clusters and metropolitan circles today.
