【摘要】：集群风险被视为影响区域经济发展的重要因素,然而构成关系的复杂性和研究过程的动态性导致现有研究难以从定量的角度分析集群网络结构的演化和风险。文章基于复杂网络的分析视角,揭示了集群网络结构与复杂网络模型之间的耦合关系,并运用仿真模拟方法构建了集群结构模型,刻画了两种风险类型下集群结构演化过程。主要结论有:内生性风险和外生性风险影响了集群内企业微观个体及网络关系的变动,使得集群风险鲁棒性具有显著差异;外生性风险下,三类集群风险鲁棒性强弱分布为中卫型混合网络型市场型;内生性风险下,三类集群风险鲁棒性强弱分布为市场型混合网络型中卫型。
[Abstract]:Cluster risk is regarded as an important factor affecting the development of regional economy. However, the complexity of the constitutive relationship and the dynamic nature of the research process make it difficult to analyze the evolution and risk of cluster network structure from the perspective of quantitative analysis. The coupling relationship between cluster network structure and complex network model is revealed, and the cluster structure model is constructed by using simulation method. This paper describes the evolution process of cluster structure under two types of risk. The main conclusions are as follows: endogenous risk and exogenous risk affect the change of micro individual and network relationship in cluster, which makes the robustness of cluster risk have significant difference; Under extraneous risk, the robustness of the three clusters is distributed as the middle guard type mixed network market type, and under the endogenous risk, the three clusters risk robustness distribution is the market type mixed network type central guard type.
