1990年代中国城际铁路集装箱运输网络空间演变

货流联系是城市相互作用的重要方面,随着经济的发展和向消费社会的转型,我国在1990年代的高附加值产品的运输显著增强.尤其集装箱运输这一高附加值的运输方式,在空间分布上发生了重要的演变.文章针对1991年和2000年200个左右城市间的集装箱进行实证分析,通过距离衰减规律、首位联系模型等对中国城际铁路集装箱流进行了透视,发现1990年代各区的集装箱流变化趋势不同,但总体上发生了分散化的演变.本文还进一步对此做出了分析.

SPACIAL INTERACTION AND NETWORK STRUCTURE EVOLVEMENT OF CITIES IN TERM OF CHINA'S RAILWAY CONTAINER FLOW IN 1990S

The pattern of freight flows is an important aspect of spacial interaction between cities.With the development of China's economy and the transition to a consuming society,the transportation of high value-added increased rapidly,and the distribution of the flows in space changed greatly in 1990s.This paper deals with the rail container flows between cities by using a O-D flow matrix between nearly 200 cities.The distribution of flows by distance and the dominant flows are discussed,contrasted with rail passenger flows.It is found that the network structure evolvement of rail container flows is very different with rail passenger flows'.While the latter has a trend of polarizing to hubs,the former shows a tendence of decentralization with different changes in different regions.And the paper tries to explain this phenomena.
