基于余弦相似性的中部六省新型城镇化时空分异研究

在传统的权重—TOPSIS法、权重—灰色关联—TOPSIS法与线性加权法基础上，提出一种基于余弦相似性的改良型评价方法，并将该方法运用到2006年～2015年中部六省新型城镇化发展水平测度及其时空分异研究中.结果表明：1)该方法切实可行，评价结果真实客观.2)研究期内中部六省新型城镇化发展水平波动趋势各异.3)新型城镇化发展水平空间差异显著，两极分化现象严重.4)新型城镇化发展水平空间分布格局既相对稳定又相对紊乱.

Spatio-temporal variation of new-style urbanization in the six provinces of Central China based on cosine similarity

Based on the traditional weight-TOPSIS method， weight-grey correlation-TOPSIS method and linear weighting method， a modified evaluation method based on cosine similarity is proposed. This method is applied to the measurement of development level and Spatio-temporal variation of new-style urbanization in the six provinces of Central China from 2006 to 2015. The results are as follows. 1) The method is practicable. The result is true and objective. 2) During the study period， the development trend of new-style urbanization in the six provinces of Central China is different. 3) The spatial difference of development level of new-style urbanization in the six provinces of Central China is significant. The polarize in the development of new-style urbanization is very serious. 4) The spatial distribution pattern of development level of new-style urbanization in the six provinces of Central China is relatively stable and disorder.
