摘　　要：研究省域中观尺度的毒品犯罪空间特征和影响因素对打击毒品犯罪、维护社会稳定具有重要意义。文章以云南省129个县区单元的毒品犯罪案件为数据,采用GIS统计分析、空间自相关分析、空间引力模型分析云南省毒品犯罪的空间差异格局和空间关联网络特征。构建由经济水平、收入水平、城镇化程度、受教育水平、流动人口、毒源地影响、地形复杂度组成的毒品犯罪影响因素指标体系,并以空间杜宾模型开展回归分析。结果表明:1)云南省毒品犯罪率呈显著的空间差异格局,高犯罪率集聚区主要分布在中缅边境;2)云南省各区县毒品犯罪在全局层面具有显著的空间关联与空间集聚特征,昆明市主城区—周边各区县以及云南边境各区县间的毒品空间关联网络强度较高;3)毒源地影响因素最为显著,呈显著负相关,距中缅边境(毒源地)距离与毒品犯罪率关系呈拉长的“倒S”型走向分布曲线,表现为大幅度下降、小幅度上升再下降的趋势。此外,经济水平对云南省毒品犯罪差异呈著负向影响,收入水平、城镇化程度为正向影响。Drug crime is a serious global problem requiring attention.This study focuses on the spatial characteristics and factors influencing drug crimes at the provincial level.Understanding these factors is crucial to combating drug crime and maintaining social stability.In the past,most studies analyzed and discussed drug crimes at the macro and micro scales;however,research on the meso scale is still relatively lacking,and the special geographical location and complex socioeconomic conditions near the border of Myanmar in Yunnan Province had a high incidence of drug crimes,so it was still necessary to study drug crimes at the meso scale in Yunnan Province.This study considers drug crime cases from 129 counties and districts in Yunnan Province and employs Geographic Information System(GIS)statistical analysis,spatial autocorrelation analysis,and a spatial gravity model to examine the spatial difference patterns and spatial correlation network characteristics of drug crime in the province.Additionally,an indicator system for drug crime-influencing factors was constructed,which included economic level,income level,urbanization level,education level,floating population,impact of drug source areas,and terrain complexity.A regression analysis using a Spatial Durbin Model was conducted to analyze the relationship between these factors and drug crimes.First,the drug crime rate in Yunnan Province exhibits a notable spatial variation pattern,wherein clusters of high crime rates are primarily concentrated along the China-Myanmar border.Second,drug crimes in different districts and counties of Yunnan Province exhibit notable spatial correlation and agglomeration patterns on a global scale.Considering the spatial distribution,two main groups with strong spatial correlation networks were identified.The first group includes Kunming's central urban area and its surrounding districts and counties.The second group consists of districts and counties along the Yunnan border.This spatial distribution aligns with the cubic function curve d
