国际生产网络与金融冲击的传播

International production networks and the propagation of financial shocks
Journal of International Economics · 2025 · Chen, Sihao

中文摘要

本文研究外部部门层面的金融冲击如何通过国际生产网络传导至小型开放经济体。运用多部门小型开放经济模型,我从理论上证明,对某一外部生产部门的金融冲击会通过价格效应影响下游部门,并通过直接需求效应以及互补或替代效应影响上游部门。这些效应通过国际生产网络发挥作用,影响小国的产出与GDP。在定量分析方面,我构建了美国部门层面的超额债券溢价并估计了用于模拟的关键参数。模拟结果显示,在全球金融危机期间,美国金融冲击解释了墨西哥GDP波动的显著比例。危机期间,国际生产网络将外部金融冲击的实际效应放大了至少三倍。

Abstract

This paper investigates how external sector-level financial shocks are transmitted to a small open economy through international production networks. Using a multi-sector small open economy model, I show analytically that a financial shock to an external production sector affects downstream sectors (through a price effect) and upstream sectors (through a direct demand effect and a complementarity or substitution effect). These effects work through international production networks, affecting the small country’s output and GDP. Quantitatively, I construct U.S. sector-level excess bond premia and estimate key parameters for simulations. The simulation exercises show that U.S. financial shocks account for a significant proportion of the fluctuations in Mexico’s GDP during the global financial crisis. International production networks amplify the real effect of external financial shocks by a factor of at least three during the crisis.
