长江三角洲空问运输联系与经济结构的时空演化特征分析

本文对长江三角洲1985-2000年各城市客、货运量进行了分析，总结出改革开放以来该区域空间运输联系的时空演化特征。长江三角洲客运量分布的廊道效应逐渐显著，货运量极化效应减弱。空间运输联系的时空演化反映了长江三角洲经济结构的推移特点。长江三角洲走廊经济突显，成为区域经济发展的有力带动轴；区域内浙东北经济崛起，成为与苏南地区相抗衡的经济板块；长江三角洲区域经济发展天平已出现向南倾斜的趋势。针对以上结论，本文认为长江三角洲地区应加快综台交通运输网络的建设，培育具有强大辐射效应的走廊经济，推动省、市之间协调合作与共同发展。

Study on Time-Spatial Revolution Characteristics of Spatial Linkage and Economic Structure

The flow of passenger and freight transport from 1985 to 2000 of every city in the Yangtze Delta is analyzed and the time-spatial revolution characteristics in this region are summarized. The flow of passenger distribution is representing a prominent corridor effect while the polarization effect of freight flow is weakening. Corridor economy is the growth axes of regional development. In the Yangtze Delta, the economy of northeastern Zhejiang is prosperous,and has canght up with southern Jiangsu gradually. These two are important economic blocks in the Yangtze River Delta. From this, the economic balance in this delta is found inclining southward. Based on these characteristics, transport network should be constructed as soon as possible in Yangtze Delta; also the corridor economy with powerful diffusion force should be fostered. All these policies will promote the cooperation between administrative regions and realize integrated regional economy.
