聚集效应主要决定于城市区域空间之间的互补性 ,而与土地价格不存在互为因果的关系。城市区域空间互补性越强 ,聚集经济越大 ,资源空间布局越有效率 ,城市通勤距离也越短。由此才可以形成有效率的城市多中心空间形态。大都市交通问题的根源在于城市资源空间布局的非互补性。 The agglomeration effect mainly depends on the complementarity between urban regional spaces, but not on the causal relationship with land prices. The stronger the spatial complementarity of urban areas, the greater the aggregate economy, the more efficient the spatial distribution of resources, and the shorter the commuting distance in urban areas. Only then can we form an efficient urban multi-center spatial configuration. The root cause of the metropolitan traffic problem lies in the non-complementarity of spatial distribution of urban resources.
