Replication Data for: Why Legislative Networks? Analyzing Legislative Network Formation

Are the social networks of legislators affected more by their political parties or their personal traits? How does the party organization influence the tendency of members to work collectively on a day-to-day basis? In this paper, I explore the determinants of the relationships of legislators in the Brazilian Chamber of Deputies. I use exponential random graph models to evaluate the relative influence of personal traits versus party influence in generating legislator relationships. Despite a focus on personalism in Brazil, the analysis reveals that the effects of political parties on tie formation are roughly equal to the effects of personal traits, suggesting that networks may make political parties much more cohesive than contemporary literature would lead us to believe.议员的社交网络更易受其所属政党还是个人特质的影响？政党组织如何影响议员在日常工作中开展集体协作的倾向？本文旨在探究巴西众议院议员间关系的决定因素。本文采用指数随机图模型（exponential random graph models），评估个人特质与政党影响力在塑造议员关系过程中的相对影响。尽管学界普遍关注巴西政坛的个人主义特质，分析结果显示，政党对关系缔结的影响与个人特质的影响大致相当，这表明社交网络可能使政党比当代相关文献所预判的更具凝聚力。
