交通经济带是区域开发的重要模式和手段,高速公路经济带是当代最重要、最普遍的交通经济带之一。通过大量实例的观察和实证分析,结合交通经济带以往的研究成果,对高速公路经济带基本特征进行了总结,分析了其形成演化机制;对布局规划的特征、内容等方面进行了初步的总结。

Formation and evolution mechanism of economic zones along expressways and their allocation and planning

Distributing models along varies traffic lines for economic development are significant in regional development. economic zone along expressways(EZAE) is one of the most important models among them. Based on the observations of a number of cases and the investigations of authentic instances, this article systematically presents a preliminary study upon EZAE and planning methods of its economic distribution. (1) Although it shares the same features in many aspects with other Traffic Economic Belts (TEB), such as TEB of railways, TEB of rivers etc., it has some unique characteristics. They are TEB's major features attributed to expressway's transportation traits, such as the rapidity of EZAE's expansion, the original features of regions adjacent to expressways, evolution and formation features. As a combination of the previous studies about TEB and economic activities related to EZAE, its definition is delivered. It is supposed as the major contribution of this article. (2) The mechanism of formation and evolution of EZAE are dilated in this article in two facets: The spatial system and the economic system. During the growing process of its spatial system, it falls into three stages: germination period, expansion period and mature period. Each has distinctive characteristic and is supported by examples. As an economic system, its formulation and evolution follow the common laws of TEB's and has its distinctive characteristics as well. (3) The major application of these theories are included in EZAE's economic allocation planing. The characteristics and contents of the plan are emphasized. The characteristics are summarized in the following aspects: the scope,the spatial feature, the relationship between the EZAE and the expressway. The contents of the plan can be laid down upon such fields: the evaluation of physical and economic conditions; boundary division; directions and strategies of development etc. At last, planning of EZAE of Shenyang Shanhaiguan is presented as a supporting case.
