摘　　要：以广东省为研究对象,构建多维指标体系,从路网密度、交通设施影响度、交通枢纽辐射水平三方面分别对各县区的差异进行分析,并综合分析其交通优势度。研究表明,广东省交通优势度呈明显的圈层分布,从中心向外围递减,从沿海向内部递减;珠三角交通优势度在全省具有明显优势,其路网密度、交通设施影响度、交通枢纽辐射水平均为全省第一层次;广东省交通优势度还与地区经济发展水平有密切关系,通过对交通优势度和人均国民生产总值进行回归分析,发现交通优势度与经济发展水平呈明显的正相关。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.
