摘要: 在完成宜宾市城区土地定级基础上,采用计量经济学方法分析发现因子间存在多重共线性,彼此间信息重叠,进而通过删掉一些因子办法修正多重共线性。研究结果表明,城镇土地定级并非选择因素因子越多越好,选择对土地质量影响重要因子,剔除影响不大因子并且相关性较高因子,既能克服因子间共线性,又能减少近一半工作量,有利于定级工作开展。

关键词: 城镇土地定级, 定级因素, 多重共线性

Abstract: The research is done on the finished land grading in Yibin city by useing the methods of quantitative economics analyse, with the conclusion that grading factors have multi-collinearity and information overlaps among them. And also multi collinearity is modified by deleting some factors. The research results indicate the important factors should be chosen, while the unimportant and relativest factors deleted, Which not only overcomes the multi-collincarity, but also reduces almost half work and benefits the development of urban land grading.

Key words: URBAN LAND GRADING, GRADE FACTORS, MULTI COLLINCARITY
