空间发展模式与中国城市增长——基于几何形态视角的考察

Spatial Development Pattern and Urban Growth in China——An Analysis Based on the Geometric Shape

城市几何形态对城市人口与经济等一系列因素的增长都起着至关重要的作用。本文系统识别了城市几何形态对城市人口、工资、房价和经济效率等方面的影响,并分析了内在机制。研究发现,城市空间形态趋于松散化会抑制其人口、工资和房价增长,阻碍了城市的经济发展;进一步的机制检验表明,松散的城市形态通过降低居民的居留意愿、内部可达性、现代化基础设施供给、环境质量以及集聚经济等方面而阻碍增长。本研究有助于理解中国城市横向扩张的空间模式对城市发展的影响,为推进新型城镇化提供了一定的政策参考。

Urban geometry plays an important role in the growth of urban population and economy.We systematically identify the effects of urban geometry on urban population,wages,housing prices and economic efficiency,and analyzes the internal mechanism.The loose urban spatial form is found to restrain the growth of population,wages and housing prices,and hinder the economic development of the city.Further examination of the mechanism shows that loose urban form impedes growth by reducing residents'willingness to stay,internal accessibility,modern infrastructure provision,environmental quality,and agglomeration economy.
