南京市主城区进城务工人员居住空间分异演化研究

A STUDY ON THE DIFFERENTIATION AND EVOLUTION OF THE LIVING SPACE OF MIGRANT WORKERS IN THE MAIN URBAN AREA OF NANJING

利用2009年和2015年南京市主城区进城务工人员的第一手问卷调查数据,结合社会经济指标及居住条件指标,运用因子生态分析法,依循“单因子分析—主因子分析—聚类分析”的基本路径,对南京市主城区进城务工人员的居住空间分异及演化特征进行定量和定性研究。研究表明:2009-2015年间持续影响进城务工人员居住分异的主因子包括住房条件、迁居特征和经济地位;而聚类形成的居住社会区虽在数量上处于稳定(4类),但其内部属性却在不断的同质与分异,并使得混杂穿插的空间结构趋于清晰与集聚化,呈现出由“扇形+散点+半环”向“扇形+散点”演化的特征。

Based on the first-hand questionnaire survey data of migrant workers in the main urban area of Nanjing City in 2009 and 2015,combined with socio-economic indicators and living condition indicators,and using the ecological factor analysis method,this paper quantitatively and qualitatively analyzes the spatial differentiation and evolution characteristics of migrant workers in the main urban area of Nanjing,following the basic path of“single factor analysis,principal factor analysis,and cluster analysis”.The results show that:from 2009 to 2015,the main factors influencing the residential differentiation of migrant workers include housing conditions,migration characteristics,and economic status;the residential social areas formed by clustering are stable in number(4 categories),but their internal attributes are constantly homogenized and differentiated,and the spatial structure tends to change from mixed and interspersed to clear and clustered,showing an evolution from a“fan-shaped+scattered+semi-ring-shaped”structure to a“fanshaped+scattered”structure.
