中文摘要:

以长三角地区16市为研究对象,从数量增长、空间格局变动及集装箱运输的空间竞争与格局演变等方面对长三角地区20世纪80年代中期以来货运量动态变化及其影响机制进行了分析。结果表明:随着经济的快速增长,长三角地区货运量、货运周转量及平均运距均大幅增长,货运量地域空间结构变动复杂,总体上极化特征突出,在时间演化上趋于区域均衡化,但同时货运量与生产地出现了一定的分离态势;集装箱运输竞争激烈,上海中心枢纽港地位初步确立,宁波港具明显的空间集聚优势,但集装箱港口体系总体空间集聚功能尚不突出。货运量动态变化在宏观层面主要受经济全球化与全球供应链及制造业模式转变的影响,在中微观尺度上,则主要受到区域经济系统与综合运输成本、区域分割与交通管理体制等的影响。

英文摘要:

Taking 16 cities in the Yangtze River Delta as the object of study,this paper analyzes the freight volume dynamics and influencing mechanism since the mid-1980s from the aspects of quantitative growth,evolution in spatial pattern,spatial competition and pattern change of container cargo flow.The results show that,both the freight volume,freight turnover and the transportation range in the Yangtze River Delta have increased by a large margin and the regional spatial structure of freight volume has a complicated change with the rapid economic growth during the past 20 years.The centralization pattern is obvious in these years,Shanghai,Nanjing,Hangzhou,Ningbo is prominent in freight volume,but the distribution of freight volume tend to equilibrium as a whole,meanwhile,the freight and production place appeared some isolated situation.The container cargo flow in the Yangtze River Delta is highly competitive.Shanghai initially established the position as the central hub port and Ningbo port has the obvious advantages of spatial agglomeration,but the general spatial agglomeration function of container port system is not prominent.The driving mechanism of freight dynamics is mainly influenced by economic globalization,global supply chain and manufacturing paradigm shift from the macroscopic level,while from the middle and microcosmic level,it was mainly affected by regional economic systems and integrated transport costs,regional segmentation and traffic management system,etc.
