在美国众议院和参议院，每一项立法都是由一位独特的立法者提出的。此外，立法者可以通过共同提案公开表达对某项立法的支持，提案人和共同提案人的网络提供了立法者之间潜在的社交网络的信息。我使用一些统计数据来描述共同赞助网络，以表明它的行为与最近研究的其他大型社交网络有很大的不同。特别是，共同赞助网络比其他网络密集得多，网络的总体特征似乎受到制度安排和战略激励的影响。我还证明了一个加权的接近中心的措施，我称之为“连通性”可以用来确定有影响力的立法者。(c)2005 Elsevier B.V.保留所有权利。
In the US House and Senate, each piece of legislation is sponsored by a unique legislator. In addition, legislators can publicly express support for a piece of legislation by cosponsoring it. The network of sponsors and cosponsors provides information about the underlying social networks among legislators. I use a number of statistics to describe the cosponsorship network in order to show that it behaves much differently than other large social networks that have been recently studied. In particular, the cosponsorship network is much denser than other networks and aggregate features of the network appear to be influenced by institutional arrangements and strategic incentives. I also demonstrate that a weighted closeness centrality measure that I call 'connectedness' can be used to identify influential legislators. (c) 2005 Elsevier B.V. All rights reserved.
