交通经济带的基础理论及其生命周期模式研究

随着生产力的发展，区域经济系统的空间演化与交通运输线的联系日益密切，一种依托交通干线不断集散、融合人口、产业、城镇、物流、能流、信息流的线状空间地域综合体不断生长并迅速发展，我们将这种独特的空间地域综合体称为交通经济带（Ｔｒａｆｆｉｃ Ｅｃｏｎｏｍｉｃ Ｂｅｌｔ）。本文系统阐述了交通经济带的基本概念、基本类型、基本性质，并创建性地提出了交通经济带的生命周期理论。

The Basic Theory and Life-Circle Pattern of Taffic Economic Belt''s Development and Evolvement

Traffic economic belt (TEB) is a kind of belt-shaped regional economic organization system whichtakes the lineal bunch of infrastructure as its development axis. Under a special historical background of itself theTEB emerges, and relying on its laws the TEB forms, develops and evolves. In the course of development ofTEB, it is an effective developing way that forms the mechanism of coordinate development of transportation andregional economy, takes the main lines of transportation as main shaft, the cities on the lines as growth centers,and the rationalization and escalation of industrial structure as the purpose of TEB development. Firstly, the pa-per defines the TEB, which also can be classified into four types: coast-oriented, river oriented, road-orientedand integrated transport-corridor TEB. Based on it, the paper deeply discusses the essential feature of TEB.Secondly, the paper puts forward the life-circle theory of traffic economic belt. The authors think TEB is an es-pecial phase in the development of the regional economic system. Just like thetypical development process of allorganisms, the traffic economic belt also has germination, expansion, mature and decline phase and shows dif-ferent space-time pattern at every phase of traffic economic belt. The development of TEB can be classified intofour stages: 1. the period of rudiment: the ways of transportation in TEB are very simple and the structure ofindustry is still rude. The center of economy in the TEB is only embodied by the function of its transportationcenter; 2. the period of bulge: the ability of transportation in the TEB has been enforced greatly. The industrywhich is based on abstracting raw material has played an important role in the whole TEB. At the same time,the function of the economic center in the TEB has been enforced and has proliferated along the lines of trans-portation;3, the period of maturation: at the period, the integrated transport corridor has shaped and the urban-ization has accelerated. The tertiary sector has become the most important industry in the TEB. Suburbanizationleads the amalgamation between the city and rural when the sub-center in the TEB has formed; 4. the period ofamalgamation and ruin: on the one hand, with the interaction of centralization and proliferation of the factor ofproduction, the borderline of the hinterland of city has died out. The urban agglomeration with different eco-nomic center network has formed based on the integrated transport-corridor. At the same time, different TEBSalso have amalgamated and interacted; on the other hand, some economic belts come to waste away because ofthe descending of the ability of transportation. At last the paper points out that research on the life-circle theoryof traffic economy belt is quite important to the adjustment of development of TEB.
