Abstract:

In the article, the indicators of transportation superiority degree are established from the aspects of road network density, regional accessibility and location superiority; and the county level transportation superiority degree is evaluated in 2003 and 2008 in Henan province by the entropy weighted technique for order preference by similarity to ideal solution method (TOPSIS) and GIS technology. Then, the spatial pattern of degree and the growth trend of transportation superiority are deeply discussed by utilizing exploratory spatial data analysis method (ESDA) method. Result show that the transportation superiority degree of every county has been enhanced continuously since 2003 and displayed a strong trend of spatial correlation, the similar units cluster in space. The spatial difference is remarkable between core areas and periphery areas, and also between plain areas and mountain areas. The hotspots counties that with better transportation superiority are centralized in the areas along the transportation corridors of Beijing-Guangzhou highway, Beijing-Guangzhou railway in Zhengzhou, Xuchang and Xinxiang. Transportation superiority in many counties in Zhongyuan urban agglomeration zones got great progress following the construction of highway network. But the relative growth rate is higher in the mountain, basin zones in south and southwest Henan than other zones. At last, it is pointed that transport infrastructure is the antecedent condition to enhance regional spatial linkages and to promote location superiority. And also transport infrastructure is the basic condition to guide direction layout of industry, expanding of urban areas, and formation of traffic economic belt, optimization of regional spatial structure and growth of urban agglomeration zones or economic zones. Therefore, leverage the advantage or circuit the disadvantages of transport infrastructure in regional development is the key factor that should be considered in regional development policy planning, industry selection and regional spatial structure optimization.

Key words: transportation superiority, entropy weighted TOPSIS method, spatial pattern, Henan
