Table 4. The overview of the indicator selection process.

Topology Feature	indicator	Selected	Reason
Bonding feature	degree	Yes	The range-of-application rule
	closeness centrality	No	The correlation rule and the concise rule
Bridge feature	(ego) betweenness centrality	Yes	The correlation rule, the diversity rule and the local topology rule
	(ego) information centrality	No	The local topology rule, the correlation rule and the concise rule
	Four structural hole indicator	No	The correlation rule and the range-of-application rule
Sub-network feature	(ego) eigenvector centrality	Yes	The correlation rule, the diversity rule and the local topology rule
	Density/clustering coefficient	No	The correlation rule and the concise rule
