【摘要】 对反映三产水平的19个观测变量建立因子分析模型,以最少因子刻画预期信息量为方向,以方差贡献为尺度,构造了4个具有代表性的公共因子,并通过载荷因子矩阵的旋转予以合理的命名解释,进一步利用公共因子的信息对我国30个省市的三产水平作了综合性评估,结论支持国家大力开发西部的政策倾向。更多还原

【Abstract】 In this paper, we establish the factor analysis model for 19 observation variables which reflect the tertiary level , construct 4 representative common factors according to the principle that use the least factors to depict the expected quantities of information and take the variance contribution as the scale, give a reasonable name interpretation by use of the rotation of load factor matrix. Furthermore, we give a comprehensive assessment for the tertiary industry level of our 30 provinces and cities by use of the information of common factors obtain the conclusion that to support the Western Development Policy of our country.更多还原
