中文摘要：

以海南省为例,选取县级及以上城市为研究节点,采用交通网络密度、邻近度、通达性等指标,构建区域交通优势度综合评价的数理模型,运用GIS网络分析技术及IDW空间插值法定量分析海南省交通网络的地域空间特征。选取了经济总量和产业结构、人口与城市化、人民生活水平、交通与城市建设等4方面共20项主要的经济指标,运用SPSS软件用主成分分析法定量分析海南省区域经济差异及空间格局。通过对海南省各县市交通优势度及经济发展水平的特点及空间结构性规律进行分析,并比较二者间的联系,结果表明：海南省通达性空间格局与经济发展空间格局并不吻合,但交通优势度与经济发展水平的空间耦合程度较高,具有较强的正相关关系,均呈现出＂凹＂型空间格局,具有明显的＂反自然梯度＂特征。

英文摘要：

This study takes Hainan as a case and its 18 counties as basic unit for analysis.Choosing 3 indexes,including transport network density,proximity and accessibility,this paper constituted the spatial mathematical model to evaluate transport superiority degree firstly.Then,by utilizing GIS and IDW（Inverse Distance Weighted） technology,this paper studied spatial characteristic of transport network in Hainan.Moreover,we selected 4 aspects,i.e.,total economic output and industrial structure,population and urbanization,living standards,transportation and the urban construction,20 indexes all together and uses SPSS16.0 software with principal component analysis to quantitatively evaluate the level of economic development.By analysing spatial characteristic and summarizing spatial disciplinarian,this paper studied the relationship between regional transport superiority and economic performance in Hainan.The results showed that there were great differences in spatial distribution patterns between accessibility and economic development.But the spatial distribution patterns of transport superiority and regional economic performance are coherent,and there are positive relations between them,which showed an opposite spatial arrangement with geographic characteristics in Hainan.
