摘　　要：基于广东省10596家化工企业数据,从产业链的视角,运用空间分析方法刻画2000—2021年广东省化工产业空间格局演化特征,并使用负二项回归模型分析化工企业区位选择的影响因素。结果表明:1)2000—2021年,广东省化工产业空间呈“西南—东北”分布,重心沿“东南—西北”迁移且距离逐渐缩短,总体呈现“集聚于珠三角地区,沿江河廊道及周边扩散”的空间演变规律,并基本形成“一中心两带”的产业格局。2)不同化工产业链的空间分布演变差异明显。其中,上游行业由离散趋于集聚,逐步形成茂名核心区及珠江东岸次核心区;中游行业呈现“珠三角大集聚,茂湛出现新热点,其他地区遍地开花”的特征;下游行业具有“珠三角集聚程度提升显著,与其他地区差距明显”的特征。3)化工产业链的空间关联性逐渐增强,且下游行业的空间相关性最强;就上中下游产业链之间关联性而言,中游与下游行业的产业联系最强。4)整体上,化工产业布局是区位条件、社会经济、政府行为和产业关联等多维因素综合驱动的结果;但不同产业链化工企业的布局因素存在差异。Given that the chemical industry is the foundation and pillar of the national economy,explorations of its spatial evolution characteristics and influencing factors are of paramount importance for optimizing regional industrial spatial layouts and promoting high-quality development.This study focused on 10,596 chemical enterprises in Guangdong Province and employed spatial analysis methods to delineate the spatial evolution characteristics of the chemical industry in Guangdong from 2000 to 2021 from an industrial chain perspective.Additionally,we applied a negative binomial regression model to analyze the factors affecting the location choices of chemical enterprises.The following are the main conclusions drawn from the results obtained:(1)Overall,the spatial distribution of the chemical industry in Guangdong Province exhibited a southwest-tonortheast trend,with the center shifting along a southeast-to-northwest axis,accompanied by a gradual reduction in distance.This resulted in a general pattern of"agglomeration in the Pearl River Delta region,diffusion along river corridors,and peripheral expansion."The specific spatial distribution pattern can be described as a"central core and two belts,"aligning with the industrial development strategies that are driving the western and eastern regions of Guangdong in concert with the Pearl River Delta region.(2)Agglomeration effects within different industrial chains were strengthened and exhibited variations in distribution.Upstream industries were primarily concentrated in Maoming,transitioning from being dispersed to being densely agglomerated and gradually forming a core area in Maoming and a sub-core area on the east bank of the Pearl River.Midstream industries were primarily clustered in the Pearl River Delta and Maoming,with limited distribution in other regions,displaying a pattern of"significant agglomeration in the Pearl River Delta,the emergence of new hotspots in Maoming and Zhanjiang,and scattered development in other areas."Downstream industries clustered in t
