The impact of the evolution of land network on spatial structure of accessibility in the developed areas:the case of Dongguan city in Guangdong province
经济发达地区交通网络演化对通达性空间格局的影响——以广东省东莞市为例

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
