珠三角地区电子信息产业空间格局及影响因素——基于企业POI数据的分析

The Spatial Pattern and Influencing Factors of Electronic Information Industry in Pearl River Delta Region:The Analysis Based On Enterprise POI Data

电子信息产业是珠三角地区战略性支柱产业。采用区位熵分析珠三角地区电子信息产业集聚水平,并基于珠三角地区9个城市的电子信息企业POI数据,通过标准差椭圆、核密度估计、空间自相关分析和热点分析方法,分析2015—2022年珠三角地区电子信息产业的空间分布格局及演变特征,进而选择合适的空间计量模型探究其影响因素。结果表明:(1)珠三角各城市电子信息产业集聚水平存在差异,广州和深圳处于领先地位;(2)珠三角电子信息产业空间布局由以广州、深圳为核心零散分布演变为向周边城市连片扩散分布;(3)经济发展水平、科研经费投入、信息化人才、科技创新能力、交通基础设施是影响珠三角地区电子信息产业空间分布的重要因素。

Electronic information industry is the strategic pillar industry in Pearl River Delta region.This article employ location quotient model to explore the agglomeration level of the electronic information industry in the Pearl River Delta region as well as the POI data of electronic information enterprises,using standard deviation ellipse,kernel density estimation,spatial auto-correlation analysis and other methods to check the spatial distribution pattern of the electronic information industry in the Pearl River Delta region from 2015 to 2022.In addition,the authors use OLS,SLM and SEM three spatial measurement models to select the optimal model to explore its influencing factors.The results show that:Firstly,There are differences in the level of electronic information industry agglomeration among cities in the Pearl River Delta,Guangzhou and Shenzhen are in the leading position.Secondly,the spatial distribution of the electronic information industry in the Pearl River Delta has evolved from a scattered distribution with Guangzhou and Shenzhen as the core to a contiguous distribution in the surrounding cities.Thirdly,R&D talents,scientific and technological innovation ability,economic development level and capital investment enthusiasm are important factors affecting the spatial distribution of electronic information industry in the Pearl River Delta region.The level of economic development,information technology talents,research and development funds input,scientific and technological innovation ability,and transportation infrastructure are the important factors affecting the spatial distribution of electronic information industry in the Pearl River Delta region.
