长三角城市经济发展的模糊聚类分析

以长江三角洲地区15个城市作为评价单元,选取2001年的相关数据,在MATLAB平台上,通过模糊聚类分析方法,依据土地面积、年末人口、GDP、财政收入、人均GDP、第一产业占GDP的比重、第二产业占GDP的比重、第三产业占GDP的比重、固定资产投资额、出口额、实际利用外资额、社会消费品零售总额、农民人均纯收入和城镇居民人均可支配收入等反应城市综合实力的主要指标对各城市进行归类,根据模糊聚类分析结果,把长江三角洲地区15城市经济发展综合实力划分为三个层次,第一层次:上海、苏州、杭州、无锡、宁波和南京;第二层次:常州、嘉兴、镇江和绍兴;第三层次:扬州、南通、泰州、湖州和舟山.提出长江三角洲地区在发展过程中应加强城市合作,提高第三层次城市的综合实力,促进一体化发展;改造传统产业,改善经济发展不平衡现象;加快发展第三产业以增加城乡居民的收入.
