基于ESDA的县域产业空间布局规划研究--以江苏省如东县为例

摘要

Based on exploratory spatial data analysis technology, this paper builds the technical route of industrial space layout planning at the county level. By taking the example of Rudong county, Jiangsu province and with the help of ArcGIS and GeoDa software, this paper carries on the quantitative analysis and spatial overlay analysis of 620 above-scale enterprises from three aspects of space distribution pattern characteristics, spatial agglomeration model and space layout inlfuencing factors. The result shows: (1) the spatial distribution of enterprises is featured by weak concentration and strong dispersion; (2) the spatial agglomeration pattern of different types of enterprises in terms of output value and employment differ with each other; (3) the trafifc channels and hub as well as industrial parks location are two major factors inlfuencing the enterprises distribution, while their impacts are different. Finally, on the basis of the above analysis conclusion, this paper puts forward the overall structure plan of industrial space layout.%基于探索性空间数据分析技术，构建了县域尺度下产业空间布局规划的技术路线。以江苏省如东县为例，运用ArcGIS和GeoDa软件的空间分析功能，对全县620家规模以上工业企业从空间分布格局特点、空间集聚模式和空间布局影响因素三个方面进行了定量分析和空间叠加分析。结果表明：①全县规模以上企业分布整体呈现“小集中、大分散”的特点；②不同类型行业企业销售收入和就业人数的空间集聚格局差异较大；③交通通道和枢纽、产业园区布局是影响企业空间分布的主要因素，但对不同类型企业的影响不同。最后，在上述空间分析结论的基础上，提出全县产业空间布局的整体结构。
