STUDY ON THE SPATIAL STRUCTURE EVOLUTION OF PORT-HINTERLAND SYSTEM:TAKING DALIAN PORT-LIAONING ECONOMIC REGION AS AN EXAMPLE
运用灰色关联分析法，研究1997-2005年大连港与辽宁经济区腹地的关联度演变，发现关联度从中部向东西再向沿海转移，呈圈层结构，且大连港与大连市关联度减弱。
This paper,on the basis of theoretical research results about the relationships of the port-hinterland at home and abroad,measures the relatedness effects of harbor-hinterland during the period 1997—2005 and analyzes the spatial structure evolution of Dalian Port-Liaoning Economic Region by grey correlation analysis method,and then analyzes its evolving mechanism.The conclusions show:①The correlation degree of Dalian Port-Liaoning Economic Region manifests a phase-by-phase evolution.The higher degree of association is in midland at the first stage,and then it transfers to the east and west,at the third stage it goes to the coastal region.②The spatial distribution pattern of correlation degree take on circles structure.③The correlation degree of Dalian Port and Dalian city diminished,the relations have entered a period of stagnation.④ Changes of correlation degree are affected by the Liaoning coastal port group.The spatial structure evolution of port-hinterland is caused by attractive function of port,element assembling of traffic network,opening-up of hinterland and the government guidance.
