摘要
从信息集聚度和信息联系度的视角构造了国家信息中心评价指标体系,并根据集聚度和联系度的高低划分了四种类型的国家信息中心:“强集聚—强联系”类型、“弱集聚—弱联系”类型、“强集聚—弱联系”类型以及“弱集聚—强联系”类型。采用了统计分析、聚类分析、因素回归分析等多种分析方法来展开对中国25个主要城市国家信息中心的相关数据进行评价分析。研究分析发现:国家信息中心指数的总体值偏低、变异系数偏高,等级分化程度总体上呈现出下降态势;大部分信息中心城市属于“强集聚—强联系”和“弱集聚—弱联系”类型,集聚度排名和联系度排名有升有降,但集聚度排名提升的城市数量较多,联系度排名下降的城市数量较多;以信息化、数据化、网络化为典型特征的分项指标差异化程度较高。
From the perspective of information agglomeration and information connection,the National Information Center’s evaluation index system is constructed,and four types of national information centers are divided according to the degree of agglomeration and connection:“strong agglomeration-strong connection”type,“weak”Agglomeration-weak ties’type,“strong agglomeration-weak ties”type and“weak agglomeration-strong ties”.Various analysis methods such as statistical analysis,cluster analysis,factor regression analysis,etc.are used to evaluate and analyze the relevant data of the National Information Center in 25 major cities in China.Research and analysis found that:the overall value of the national information center index is low,the coefficient of variation is high,and the degree of hierarchical differentiation is generally declining;most information center cities belong to“strong agglomeration-strong connection”and“weak agglomeration-weak connection”types,agglomeration rankings and connection rankings have both increased and decreased,but the number of cities that have increased in agglomeration rankings is higher,and the number of connected rankings has fallen by a higher number;differences in sub-indices with typical characteristics of informatization,digitization,and networking.The degree of chemistry is relatively high.
