【摘要】 本文将包含人口流动摩擦的空间均衡模型与我国地级市数据相结合,研究人口迁移对我国劳动力资源配置、城市规模与经济效率的影响。研究发现,我国城市的劳动力进入壁垒远高于农村非农业部门,同时大城市的劳动力进入壁垒高于中小城市,导致我国城市化滞后于工业化,城市规模分布呈现出中小城市偏多、大城市偏少的扁平化特征。进一步降低人口流动壁垒将有利于我国城市规模的扩张与劳动力资源配置效率的改进。更多还原

【Abstract】 In this paper we investigate the effects of internal migration on labor allocation, city size, and aggregate productivity in China based on a spatial general equilibrium model with imperfect labor mobility and prefecture-level data.We find that China’s urbanization lags behind its industrialization and the city size distribution is relatively flat since labor entry barrier of each city is higher than that of its rural nonagricultural counterpart, and the labor entry barrier of large cities is higher than that of small and medium-sized cities.Further lowering migration costs will induce an expansion of cities and a rise in aggregate productivity.更多还原
