Network to passion or passion to network? Disentangling entrepreneurial passion selection and contagion effects among peers and teams in a startup accelerator
研究创业加速器中同伴网络与创业激情的共同演化，发现激情相似性驱动社交选择（占34%），而社交传染解释57%的激情相似性，且团队内传染更强，但对发明激情无显著影响。
Entrepreneurial passion is socially contagious. However, do entrepreneurs also select whom they interact with based on passion similarity? The complex interdependencies between social networks and entrepreneurial passion remain undertheorized and empirically puzzling. Using a stochastic actor-oriented model (SIENA) and four waves of panel data, we test hypotheses about the co-evolution of social networks and entrepreneurial passion during a 5-month startup accelerator program. We observe that social ties occur more frequently among peer entrepreneurs who are similar in levels of passion for founding. Initial homophily selection explains 34% of this observed similarity whereas social contagion explains 57%. Finally, we find that passion for founding is more contagious among members of startup teams than across other peer ties. Surprisingly, none of these effects are significant for passion for inventing. We discuss the theoretical and practical implications of these findings.
