The structure of collaboration networks: Findings from three decades of co-invention patents in Chile
作者：
Highlights：
• Inventor networks exhibit power law and small-world properties.
• Added connections are chosen according to a sublinear preferential attachment.
• Positive autocorrelation between highly and lowly productive inventors was detected.
• Apparent differences in collaboration patterns between networks are highlighted.
• The lack of local hubs may inhibit the development of new inventions.

•Inventor networks exhibit power law and small-world properties.•Added connections are chosen according to a sublinear preferential attachment.•Positive autocorrelation between highly and lowly productive inventors was detected.•Apparent differences in collaboration patterns between networks are highlighted.•The lack of local hubs may inhibit the development of new inventions.
