Abstract: This paper defines the spatial scale of the yangtze river delta urban agglomerations, and then uses the space clustering analysis application of GIS to analyze its economic space, based on the related data of cities in 2013, respectively from the global clustering test and the local clustering test. The study shows that there are significant features of spatial cluster for economic output and production factors from the global perspective. And from the local perspective, GDP and per capita GDP high-high cluster in Shanghai, Suzhou and other cities. Meanwhile labor,capital,technology,energy and other economic production factors high-high cluster in Shanghai, Suzhou and other cities too.

Key words: space clustering analysis, global clustering test, local clustering test, yangtze river delta urban agglomerations

摘要： 本文在界定长三角城市群空间范围的基础上,利用长三角城市群各城市2013年相关数据,应用GIS的空间聚类分析功能分别从全局聚类检验和局部聚类检验两个方面分析了长三角城市群的经济空间集聚特征。研究结果表明长三角城市群的经济产出和经济生产要素在全局上存在空间集聚现象,在局部上,GDP、人均GDP等经济产出在向上海市、苏州市等个别城市高-高集聚,而劳动、资本、技术、能源等经济生产要素也在向上海市、苏州市等个别城市高-高集聚。
