摘要
以2012年重庆市139个部门投入-产出表为基础,借鉴主成分-因子分析法和Czamanski法,共辨识出20个产业集群,并利用局部空间统计方法,测度产业集群局部空间的自相关系数,在此基础上进一步分析重庆市产业集群的空间布局特征。结果显示:1)不同产业集群的空间局部自相关度存在明显差异,纺织服装业集群最低(自相关系数M值为0.1221),局部相关性和空间邻近不明显;而都市型工业(M值为0.399 4)、交通设备制造业(M值为0.424 7)、电子及通信设备制造业(M值为0.419 2)、汽车及其设备制造业(M值为0.466 9)等4个核心制造业的局部空间自相关度较高,在重庆市具备独特优势。2)重庆市产业集群的空间分布主要集聚在主城区和近郊县域,并向外部区域延伸;同时,产业集群仍然存在发展不平衡、区域布局和功能重叠等问题,这些因素对产业集群的集聚效应和产业特色发展有一定的限制作用。
To 139 sector input-output tables is based on industry clusters draw quantitative identification method：Principal component analysis and Czamanski were identified 20 industrial clusters;the use of local spatial statistical methods measures the spatial distribution characteristics of industrial clusters,and analysis spatial distribution characteristics of Chongqing industrial clusters.The results：different industrial clusters of local autocorrelation there are significant differences,of which：textile and garment industry cluster minimum（the selfcorrelation coefficient M is 0.122 1）,the partial correlation and spatial proximity is not obvious;and urban industry（0.399 4）,transportation equipment manufacturing（0.424 7）,electronic and communication equipment manufacturing（0.419 2）and motor vehicles and equipment manufacturing（0.466 9）were high autocorrelation coefficient value of M,in Chongqing have unique advantages.Overall,Chongqing spatial distribution of industrial clusters mainly concentrate in the main city and suburban areas,and extends toward the outer region;at the same time,there are still uneven development of industrial clusters,regional distribution,overlapping functions and other issues,limiting the combined effect of industrial clusters development and industry characteristics.
