长春—吉林经济带的形成与空间结构特点研究

A STUDY ON THE FORMATION AND SPATIAL STRUCTURE OF "CHANGCHUN-JILIN" ECONOMIC ZONE

文章通过对经济带概念的分析,构建经济带的形成和演进理论,认为经济带有等级、层次之分,其时空演进的理论为增长极理论—点—轴发展理论—梯度推移理论。在此基础上,论证长春—吉林经济带的存在性,分析其结构、功能及空间联系形式。作者认为,长春—吉林经济带目前是一个弱经济带,其扩散效应较弱,随着其扩散效应的增强,长春—吉林经济带将能够从整体上带动和促进吉林省的经济发展。

Through studying the concept of economic zone, the article tries to conceive the theory of formation and evolution of economic zone. Economic zone has different scales and levels, and its evolutional theory of time and space are growth theory, pole-axis theory and step-passing theory. There are four stages in the formation of economic zone, the first is the emergence of growth pole; the second is that the axis appears between the main two cities; the third is that more growth pole produce and being connected by sub-axis; the forth is that all the poles and axis merge and produce diffusing effect. Based on these theories above, the article argues the existence of 'Changchun-Jilin' economic zone, and further analyses its structure, function and spatial contacting form. The author thinks that Changchun city and Jilin city are the most two important growth poles in Jilin province by using synthetical index method and center-site method. Acted as the two strongest cities in Jilin province, Changchun city and Jilin city have connected to integral whole through the transportation, and while small cities between which accept radiating, they also radiate outwardly. With increasing in its diffusing effect, 'Changchun-Jilin' economic zone would have important meaning in regional development in Jilin province. Because of the stronger creative ability and the higher technology level in 'Changchun-Jilin' economic zone, the factors, such as technique, funds, knowledge etc. , would extend continuously and outwardly by network, and affect the regional economy development. First, 'Changchun-Jilin' economic zone can promote the region's industrial structure in middle area of Jilin province through industrial diversion; second, some small cities, such as Jiutai city, Yushu city, Dehui city and Siping city, become new increasing pole, and further strengthening the economic radiation function; Third, because of Yanbian district in reality developing in the form of increasing pole, 'Changchun-Jilin' economic zone can connect to integral with Yanbian district in taking face east extension to, and arouse the development of the Jilin province in whole; Fourth, it can offers the necessity for the westward of Jilin province such as talented person, funds, technique etc. In long run, 'Changchun-Jilin' economic zone would drive economic development of Jilin province with its increasing diffusing effect.
