对创新集群的结构进行了深入分析,将其结构抽象为知识网络、产业网络、价值网络和服务网络四大网络。设计了创新集群结构评价的指标体系,并运用主成分分析法对北欧国家ICT创新集群结构分别进行了实证评价和分析。评价结论基本证实了指标体系的有效性和方法具有逻辑自洽性。 The structure of innovation clusters is analyzed in depth, and its structure is abstracted into four networks: knowledge network, industrial network, value network and service network. The index system of innovative cluster structure evaluation was designed. Empirical analysis and evaluation were conducted on the structure of ICT innovation clusters in the Nordic countries by using principal component analysis. The conclusion of the evaluation basically confirms the validity of the index system and the method has logical self-consistency.
