基于投影寻踪模型的河南省城市综合承载能力的比较分析

Evaluation of Urban Bearing Capacity in Henan Province by Projection Pursuit

本文着眼于城市承载力的内涵要素,从多视角多维度构建城市承载力的指标体系,将投影寻踪模型运用到城市综合承载力评价中,丰富和完善了对城市承载力评价的理论体系.尝试以河南省九个主要城市2014年的统计数据为基础,进行实证分析.结果表明,相比其他城市,郑州、洛阳等城市综合承载力指数较高,但是在部分领域也存在一些短板.

This paper focuses on the connotative factors of urban bearing capacity,constructs a multi-dimensional evaluation indicator system for assessing urban bearing capacity. Projection pursuit model is used in this indicator system to improve and optimize the theoretical framework of urban bearing capacity evaluation. 2014 data of 9Henan cities are used as the basis,on which an empirical study is implemented and as the results indicate： several such cities like Zhengzhou and Luoyang,compared to other cities,are of relatively high bearing capacity,but still have certain disadvantages in certain areas.
