中文摘要：

知识冗余会影响知识传播效率,降低异质知识流强度,进而影响创新节点知识增量的产生。从关系维度、结构维度以及时间维度分析知识冗余对知识流强度的约束,提出了基于知识冗余的区域知识增量模型,进而通过分析创新网络对知识冗余的影响,以提升异质知识流强度为导向,探讨了知识冗余削减机制。

英文摘要：

Knowledge redundancy influenced the efficiency of knowledge dissemination, weaken the intensity of heterogene- ous knowledge flow and further affect the increment of innovation knowledge. By analyzing the relations dimension, struc- ture dimension and time dimension of knowledge redundancy and its constraints on knowledge flow intensity, the regional knowledge increment model based on knowledge redundancy is proposed, and then through analyzing the effect of innova- tion network on knowledge redundancy, knowledge redundancy reduction mechanism is explored in order to enhance the strength of heterogeneous knowledge flow.
