Summary table of measurement indicators

Variable Measurement indicator
Network centrality The connected object has a high degree of information exchange through the company.The company uses the relationship bridge to a high degree.The company has a high degree of robustness in the relationship with the connected object.
Network scale The number of companies in the network.The number of research institutions in the network.The number of universities in the network.The number of governments in the network.
Network strength The company has frequent contact with connected objects.The contact between the company and the connected object lasts for more than three years.The high emotional intensity between the company and the connected object.
Social capital There are abundant subjects in the IUR cooperation network.The company and the connected object provide additional help to each other.The company has the same value orientation as the connected object.
Innovation performance The company spends more on technology development than its competitors.The company has more patents than its competitors.The company develops new products faster than its competitors.The company has more technological innovators than its competitors.
