地级以上城市的城市职能分类——以江浙沪地区为例

城市职能是城市在区域发展中所承担的分工。在国家或区域范围内，按照城市职能的相似性和差异性，研究城市与城市之间的分工，可以得到城市体系的职能结构。要得到城市体系的职能结构，首先要进行城市职能分类。对城市职能分类的方法经历了从简单到复杂、从定性到定量、从单指标到多指标的过程。以江浙沪地区25个地级以上城市为例，按照多因素分析和统计分析相结合的方法，研究得到这一城市体系的城市职能结构。上海是处于第一层级的综合性巨型城市，南京、杭州是处于第二层级的综合性特大城市，宁波、温州、绍兴、苏州、无锡是处于第三层级的综合性或专业化大城市，南通、盐城、徐州、金华是处于第四层级的综合性或专业化中等城市，其它12个城市则是处于第五层级的小城市。

URBAN FUNCTION SYSTEM OF MUNICIPALITIES IN REGIONS OF JIANGSU AND ZHEJIANG PROVINCES AND THE CITY OF SHANGHAI

The urban function was studied in this paper,with urban standing as a territorial division of production.Twenty-five municipalities in regions of Jinagsu and Zhejiang Provinces and the city of Shanghai were included in the present study,with the application of multi-factor analysis and statistical analysis.The territorial division of production was performed among these municipalities.The urban function system was then defined upon their functions.Shanghai is of the first level with a comprehensive ultra-urban.The city of Nanjing,and city of Hangzhou are of the second level,with extraordinarily large urban.Cities including Ningbo,Wenzhou,Shaoxing,Suzhou,Wuxi are at the third level,with comprehensive or professional large urban.Other cities such as Nantong,Yancheng,Xuzhou,Jinhua are the forth level,with comprehensive or professional medium size urban.All others are of the fifth level,with small urban.
