聚类分析法在居民消费结构地区差异分析中的应用 摘 要 居民消费结构是指人们在生活消费过程中各种社会因素与自然因素之间的相 互关系和数量比例的总和。它反映了一定社会经济条件下人们对各类商品及服务的 需求结构，体现了一个国家的经济发展水平和居民生活状况，同时也是国家进行宏 观经济分析和决策的重要依据。 本文选用了与城镇居民消费结构相关的8个统计指标。它们分别是：食品、衣 着、家庭设备用品及服务、医疗保健、交通和通讯、娱乐教育文化服务、居住以及 杂项商品和服务。运用聚类分析和因子分析方法，按照消费水平，对我国 2003 年 31 个地区的城镇居民人均消费结构进行了分析。不仅从总体上掌握了消费结构类 型的地区分布，而且系统阐述了各地区消费结构的特点和相应的影响因素，另外针 对城镇居民消费结构的地区差异提出了几点优化建议。 关键词：消费结构，地区差异，聚类分析，因子分析 I 聚类分析法在居民消费结构地区差异分析中的应用 Abstract The consumption structure of residents means the correlation and the total of the quantity comparisons of the various social factors and natural factors.
