产学研合作网络及鲁棒性研究

Network in cooperation of industry-university and research institute is the organization which industries, universities and research institutes in order to meet their respective needs to cooperate based on some social contacts, trust and share complementing resource. The organization has the features and basic structure of social network. From the perspective of complex network and make the joint patent data of Shandong as the example, the paper abstracted the industries, universities and research institutes as nodes and if they had joint applied patent then there has an edge between them, based on the nodes and edges we constructed the real network. Through research on the statistics characters, such as density, degree distribution and average path length, we found that the network is composed of many connected components, cooperative level is low, but the knowledge spread fast and efficient in one component, and the network has the characteristic of scale- free. From the perspective of node failure and edge failure to study the robustness of the network, we found that the network when faced randomly deleted nodes or edges and edge betweenness preferred deleted edge has high robustness, while the network when faced node degree preferred deleted nodes and node betweeness preferred deleted nodes is very fragile.
