Networks and Trade
综述了关于企业间贸易连接的研究，利用国内外交易数据揭示了买方和供应商在生产网络中的异质性，并探讨了多对多匹配环境下的静态与动态理论。
Trade occurs between firms both across borders and within countries, and most trade transactions include at least one large firm with many trading partners. This article reviews the literature on firm-to-firm connections in trade. A growing body of evidence coming from domestic and international transaction data has established empirical regularities that have inspired the development of new theories emphasizing firm heterogeneity among both buyers and suppliers in production networks. Theoretical work has considered both static and dynamic matching environments in a framework of many-to-many matching. The literature on trade and production networks is at an early stage, and there are many unanswered empirical and theoretical questions.
