中文摘要：

新中国成立以来,在政策表达层面,我国人口城市化空间集聚政策先后经历限制大城市发展小城镇、大中小协调发展和发展城市群三个阶段;而从行为实践层面,我国人口城市化空间集聚呈现城市规模与人口集聚规模＂正相关＂、大城市是人口空间集聚＂主力军＂和大小城市增速＂两头快＂三大特点,以＂300万＂人口为分割点,总体呈现明显的＂大城市＂特色。随着城市群的崛起,未来我国人口城市化空间集聚将呈现城市群成人口空间集聚新形态、大城市人口空间集聚规模趋缓、中等城市成人口空间集聚主力军、小城市人口空间集聚能力逐步增强等四大趋势。

英文摘要：

Since the foundation of People＇s Republic of China,in the policy expression level,China＇s population urbanization spatial agglomeration policy has experienced the three stages：inhibiting large city and developing the small city,large and small coordinated development,developing urban agglomeration.From the behavior practice,China＇s population urbanization spatial agglomeration appear three characteristics that city scale and population agglomeration scale is positively related,big city is the main force of population spatial agglomeration,increase rate of big and small cities are both high,taking three million population as the segmentation point,generally appear ＂big city＂ characteristics.With the rise of urban agglomeration,in future China＇s population urbanization spatial agglomeration will show four trends,which include urban agglomeration become the new form of population urbanization spatial agglomeration,big city population spatial agglomeration scale will gradually slowdown,middle city become the main force of population urbanization spatial agglomeration,population urbanization spatial agglomeration ability of small city will increase stepwise.
