基于GIS空间分析法的辽宁省产业结构空间格局演变研究

Spatial Pattern of Industrial Structure Evolution in Liaoning Province Based on GIS Spatial Analysis Method

运用产业结构系数、空间自相关、区位商等方法,基于Arc GIS、Geo Da等地统计分析软件,从产业结构系数的空间关联和产业内部结构两方面,对1997—2012年辽宁省产业结构空间格局进行了研究。结果表明:辽西北地区产业结构水平较低,辽中地区产业结构水平较高,并有向东北部扩散的趋势。第一产业主要分布在辽西地区;第二产业以采矿、制造业为主,分布广泛;第三产业除沈阳、大连两市外,整体发展水平不高。在对各市主导产业和优势产业进行分析的基础上,提出了优化布局方案。

Using the industrial structure coefficient, spatial autocorrelation and location quotient method, based on ArcGIS, GeoDa statistical anal- ysis software, this paper studied the spatial pattern of industrial structure in Liaoning Province from 1997 to 2012 from the two aspects that industrial structure coefficient of spatial association and industry internal structure. The results showed that the level of the industrial structure in the area of the northwest Liaoning Province were lower, the middle of Liaoning were higher, and had a tendency to spread to the northeast. The primary industry were mainly distributed in the western Liaoning region, the secondary industry were mainly based on mining and manufacturing, the overall level of develop- ment of the tertiary industry were lower except Shenyang and Dalian. Finally, this paper analyzed the cities＇ leading industry and the competitive in- dustries of Liaoning Province, and put forward to the program of optimization layout.
