应用自组织映射对中国地区产业结构的聚类分析

Self Organization Maps for Clustering Regional Industrial Structure in China

为了研究地区产业结构的空间分布规律,采用自组织映射的聚类方法,对 2003年中国省级地区的产业结构进行了聚类分析。结果表明,自组织映射的方法能够将地区产业结构在输出层聚成 5个区域。通过对聚类结果进一步的分析得到,在目前的经济水平下,工业化水平是中国地区产业结构差异性的主要因素。

In order to research the spatial distribution law of the regional industrial structure,the self organization maps method is used to cluster and analyze the regional data in China 2003. The clustering result shows that the SOM method can cluster the regional industrial structure into five categories in the output layer. Also it is found that the industrialization level is the primary factor of the diversity in the current regional industrial structure of China.
