从社会和地方融合、均衡性与土地异质性、交通网等级体系和支路网与交通可持续性四个角度探讨西班牙交通基础设施网建设对土地开发和土地规划相关国家法规的影响。从城市地理学视角分析中央政府基于改善城市和区域连接度和可达性进行的高速公路网、高铁网、机场和港口等交通基础设施规划，通过1950年代以来土地开发和房价涨跌、新兴产业培育和交通状况改善刺激不同级别城市蔓延和分化的人口增长，重塑西班牙国家城市体系格局。随后，概括了蔓延的城市增长模式和房地产与交通投资泡沫破裂后带给区域增长中心的影响，对通过交通基础设施规划进行投机性投资政策进行了批评。最后建议中央政府应该避免投机投资行为，基于现有的城市体系层级改善核心城市和大城市周边的机动性，优化基础设施建设，建立新的城市与区域增长模式。

英文摘要：

In Spain＇s urban context, the 2008 world-wide economic crisis has not only disclosed the existence of a housing bubble but also revealed the important role of transport infrastructure investments in the Second Circuit of the Capital. The development of transport infrastructures is highly progressive in Spain, since there have been increasing European investments and it is quite easy to obtain credit for large transport projects. As a result, a huge amount of high-capacity roads and high-speed railways are built. However, the radial transport layout focuses too much on the capital city and thus leaving other cities somehow disconnected. Furthermore, the development of transport infrastructures are mainly based on political and economic considerations, which results in an underused transport systems. This article analyzes the importance of transport infrastructures in the urban expansion process in Spain, as well as discusses the impact of transport infrastructures on the metropolitanization process and on the newly-formed urban structures. Finally, this article highlights the existence of transport infrastructure bubbles and their aftereffects.
