以广东省东莞市为例，分析了改革20多年来公路、铁路网对城市可达性空间结构的影响。随着交通网络的成熟，可达性空间结构呈现出同质化发展态势，经济发达地区的“时空紧缩”过程明显改变了可达性的决策条件。区位决策随着可达性的变化而变化，导致区位决策的区域和范围不断扩大。理想情况下，一个地区的可达性越好，越容易促进经济发展，良好的交通条件表现出良好的可达性。以东莞为例，可达性最好的地区是经济发展较快的地区，但不是最快的值得注意的是，由于交通便利的上级条件，加上经济发展的需求，东莞市面向香港的可达性最好的地区正在迅速发展，东莞市可达性空间结构的变化只是交通网络中的一个短暂时期广州-香港运输通道未来面临的问题是可达性空间结构的改善，特别是广州-香港联系带的可达性空间结构的改善
In this paper, we analyze the impact of road and railway network on the spatial structure of accessibility,since reform and opening up in the past 20 odd years using Donguan city in Guangdong province as an example. As the transport network goes to mature, the spatial structure of accessibility presents homogeneous development regime, and the "Time Space Astringency" process of economically developed region apparently changed the decision making conditions. Locational decision has been changed with changes of accessibility, leading to expansion in both area and scope of the locational decision Ideally speaking, the better a accessibility in a district, the easier to improve the economic development, good transportation condition has showed fine accessibility Take Dongguan for example, the district which has best accessibility is the district whose economy is developing faster, but not the fastest one What is notable is that because of the superior condition of accessibility, together with the demand in the economic development, the district with best accessibility facing Hong Kong in Dongguan is developing dramatically in the estate The changing situation of the spatial structure of the accessibility in Dongguan is just a fleeting period in the transport network development Dongguan must strengthen transport construction in the mid western part in order to make the accessibility of the corridor's interior part stay at the same level What the Guangzhou Hong Kong Transport Corridor will face in future is the improvement of the accessibility's spatial structure,especially the contact zone between Guangzhou and Hong Kong
