Abstract

Buyer-seller relationships among firms can be regarded as a longitudinal network in which the connectivity pattern evolves as each firm receives productivity shocks. Based on a data set describing the evolution of buyer-seller links among 55,608 firms over a decade and structural equation modeling, we find some evidence that interfirm networks evolve reflecting a firm's local decisions to mitigate adverse effects from neighbor firms through interfirm linkage, while enjoying positive effects from them. As a result, link renewal tends to have a positive impact on the growth rates of firms. We also investigate the role of networks in aggregate fluctuations.

摘要

公司之间的买卖关系可被视为一个纵向网络，其中连接模式会随着每家公司受到生产率冲击而演变。基于一个描述55608家公司之间买卖关系十年演变情况的数据集以及结构方程模型，我们发现一些证据表明，企业间网络的演变反映了一家公司通过企业间联系减轻相邻公司不利影响同时享受其积极影响的局部决策。因此，关系更新往往对公司的增长率产生积极影响。我们还研究了网络在总体波动中的作用。
