Multi-Dimension Analysis of Guangdong Spatial Transport Superiority
Transport is vital to regional development, which has impact not only on economy but also on society and politics. The level of regional transport consists of the interior connection and inter-regional accessibility, so the transport superiority can be quantified by multi-dimension system analysis. The system includes three dimensions: transport network density, influence degree of transport facilities and diffusion effect of the transport hubs. On the basis of mathematical evaluation model,this paper studies the spatial transport superiority in Guangdong Province, and some conclusions have been drawn. First, the transport superiority of the Pearl Delta is much higher than that of other areas in the province, where the three dimensions are all above the provincial average level. The transport superiority is higher on the east of the Pearl River mouth than on the west. Second, the spatial characteristic shows the transport superiority’s layer-loop structure. The superiority decreases gradually from the core (the Pearl River Delta) to the margin (the north mountain area), from the coast areas to the inland. Moreover, the study also reveals that there is a positive relation between transport superiority and economic development level. The transport superiority is proportionate to the economic development level that can be proved by the regression analysis with transport superiority degree and GDP per capita.
