Interpretation and calculations
Measurement of business network in this study
Density
Whole networks
Represents the closeness of a network Calculated by the amount of potential connections between individuals that are actually present
Relationships of actors, network closeness, and variation
Network centralisation
Whole networks
Reflects the extent to which interactions are concentrated in a small number of individuals rather than distributed equally among all members Calculated by the sum of the differences between the largest individual centrality and all the other individuals in the network was divided by the maximum possible sum of differences
Differences between high centrality critical actors and other actors, and the trends over time
Centralisation index
Whole networks
Represents an estimate of the deviation of the largest values of betweenness centrality computed in the section nodes, from the value computed for all other nodes Calculated by dividing the sum of the differences between the largest individual relative betweenness centrality and all the other individuals in the network by (N-1), where N represents the number of nodes
Differences between high betweenness centrality critical actors and other actors, and the trends over time
Degree centrality
Individual
Represents the level of importance of a particular node in a network Calculated by the total number of ties to other nodes in the network
Location of each actor in a business network, indicating their market position
Betweenness centrality
Individual
Represent the extent to which an actor has control over information flowing between others Calculated by the number of times that a node lies along the shortest path between two other nodes
Location of each actor in a business network, indicating their ability to control the market opportunities
