The Relationship Between the Spatial Distribution of Commercial Networks and Street Centrality in Changchun
研究了长春市街道中心性（接近度、中介度、直线度）与不同类型商业网络空间分布的相关性，发现不同商业类型受不同中心性指标影响。
Street centrality is calibrated in a multiple centrality assessment model(MCA)composed of multiple measures such as closeness, betweenness, and straightness. The paper examines the geography of three street centrality indices and their correlations with various types of commercial networks in ChangChun. The focus is on what type of street centrality(closeness, betweenness, and straightness) is more closely associated with which type of commercial network. And then the KDE method is applied to both street centralities and commercial networks so that the correlations between them can be examined. Results indicate that street centralities are correlated with the spatial distribution of commercial networks in ChangChun, except production material market. Department stores and specializing shops correlate highly with the closeness of street network. The betweenness of street network, however, has a higher impact on the spatial distribution of supermarkets, and building-material shops. Besides, the spatial distribution of consumer markets is more affected by the straightness of street network. There exists non- conformity between the spatial distribution of department stores,specializing shops, building- material shops, consumer markets, production material market, and street network centralities.
