淮海经济区城市空间影响范围与城市经济区划分

A RESEARCH ON THE ZONES INFLUENCED BY URBAN SPACE AND THE DIVISION OF URBAN ECONOMIC REGION IN HUAIHAI ECONOMIC ZONE

运用因子分析法求取淮海经济区20个地级市的综合实力指数及等级划分。根据城市综合实力指数和等级划分,选取4个一级城市作为中心城市,然后运用断裂点公式计算中心城市与邻近城市的空间影响距离。再根据空间影响距离划分各中心城市经济影响区范围。最后以城市经济影响区为基础,综合考虑各城市的区域特征、发展潜力、现有经济规划、历史习惯和人文特征,确定城市经济区界限。研究淮海经济区城市经济区形成和划分的目的是指明各城市在整个区域内劳动地域分工中的地位,了解城市经济发展现状和主要特点。

The authors review the theories related to economic hinterland and analyze the methods of spatial definition. Furthermore, they set up new theory system and new method of definition. The division of urban economic region reflects the regional economic growth in space requirements, breakthroughs in the production of a single element of the regional resources and constraints, and could achieve coordinated development of regional economy. Huaihai economic zone is a developing region in coastal area of east China. Based on the evaluation of regional economy spatial organizing in Huaihai economic zone, according to social and eco- nomic development, the authors insist that it is a necessary to build the regional space economic organization on the basis of urban economic region to complement the regional economic coordination development in Huaihai economic zone. Firstly, the authors review the theories of the urban economic region. Secondly, based on the circle development theory, the center-periphery theory and the spatial interaction theory, this paper establishes a comprehensive strenth evaluation system of the cities in Huaihai economic zone with the method of main components analysis. By using mathematical methods, this paper tries to achieve the comprehensive strength evaluation and grade the 20 cities. According to the city＇s comprehensive strength index, the authors select 4 first-class cities as central cities, and then evaluate their spatial influence on their neighboring towns. Thirdly, according to the power of space influence, this paper confirms the economic region of Huaihai economic zone. Based on the economic impact, this paper carries out a comprehensive study of the regional characteristics of cities, their conditions, development potentiality, traditional custom, humanistic characteristics, then identifies the urban economic zone boundaries. Huaihai economic zone is divided into 6 urban economic regions which are central economic region, northwest economic region, northeast economic region, southeast economic region, southwest economic region and western economic region.
