基于因子分析法和聚类分析的我国各省市建筑业竞争力评价研究

对各地建筑业的竞争力进行合理客观评价,分析其在不同方面的优劣对于建筑业因地制宜发展有着重要意义。通过构建我国建筑业竞争力评价指标体系,选取国家统计局关于建筑业的统计数据,首先应用因子分析法对这些数据进行处理,得到三个影响建筑业竞争力的公共因子即规模因子、技术因子和盈利水平因子,进而计算各公共因子得分及全国31个省市建筑业综合竞争力水平的得分,对各省市建筑业的综合竞争力和优劣进行评价。其次,在因子分析的基础上,运用聚类分析的方法将31个省市分为五大类,并对每类地区的建筑业特点进行全面分析,以便为我国建筑业发展战略和相关政策的制定提供参考。
