摘要
针对我国各省(直辖)市的2003年度经济数据,选取18个经济指标进行主成分分析,得到资本类、人力类、知识类、制度类和生活类共5类经济类别指标;再对经济类别指标进行系统聚类分析,得到我国3类不同的地区经济类型;在阐明聚类结果的直观意义后,利用实例进行判别分析,以确认聚类效果.聚类结果为制订有针对性的地区经济发展战略提供依据.
From the economic data in our country in 2003, 18 economic variables were selected. Firstly, these variables were reduced, five economic type variables including capital, labor, knowledge, social system and life.
