中国信息服务业空间集聚研究

Spatial Agglomeration Study of China's Information Service Industry

通过产业集聚的EG指数对中国各省份信息服务业的空间集聚程度进行研究,得出集聚程度比较显著。在此基础上,找到这一服务业的两个相关指标,利用产业集中度CRn判断出信息服务业主要集中于北京、广东等六个地区,然后对两指标数据进行无量纲化处理,加权求和得到新的综合指标,最后对这一新指标进行了系统聚类分析,得知这一产业主要集中在北京和广东两个地区。

The industrial concentration index of information service industry of China＇s each province is used to study thespatial agglomeration degree, and it is reached that the degree of agglomeration is great. On this basis, two related indicatorsof the service industry are found, using industrial concentration to determine that information services are mainly concentratedin six areas such as Beijing, Guangdong and so on, then the two indicators data are dimensionless processed, and the newcomprehensive index is got by weighted summation. Finally, the new index is system clustering analysed, the result showsthat the industry is mainly concentrated in Beijing and Guangdong.
