摘要
深入研究广西的物流业空间布局,对区域发展有重要现实意义.但在分析常规和传统的数据时,往往要考虑其滞后性、不足性及结构化等缺陷,而使用时效性高、精准性强、可直接用于研究样本数据本身的POI物流数据能规避大多缺陷.运用核密度估计法、缓冲区分析、平均最近邻指数等方法对广西物流产业空间布局特征进行分析.结果表明,广西物流业布局表现出集聚特征,在空间上呈现"东南走向密、西北走向疏"的特点,物流业区位分布具有明显层级性和不均衡性,物流业布局选择多呈现城市中心化、郊区化少特征.总体上,广西物流业仍处于发展期,表现为"一极化中心,东南走势"的空间格局,不同类型的物流活动表现各有差异.
Abstract
It is of great practical significance to study the spatial layout of logistics industry in Guangxi.However,when analyzing conventional and traditional data,it is often necessary to consider its defects,such as lag,insufficiency and structure,and the use of high timeliness and accuracy.POI logistics data of the sample data itself,which can be directly used,can avoid most defects.The study analyzes the spatial distribution characteristics of logistics industry in Guangxi with kernel density estimation,buffer zone analysis and average nearest neighbor index,etc.The results show that the distribution of logistics industry in Guangxi presents the characteristics of agglomeration,showing the characteristics of"dense southeast and sparse northwest"in space.The distribution of logistics industry has obvious hierarchy and imbalance,and the distribution of logistics industry is mostly urban center and less suburbanization.In general,logistics industry in Guangxi is still in the development stage,showing"one polarization center,southeast trend"in space,and different types of logistics activities in performance.
