英文文献摘要：
This paper focuses on the survival capacity of the trade flows in international production networks, extending the limited empirical evidence. Firstly, we emphasize that these trade relationships are longer-lived than trade in final goods. Secondly, we try to delimit the factors that explain this. Using time-discrete duration models, which control for the existence of unobservable heterogeneity, we find that variables such as initial value of the trade flow, geographic and product diversification, institutional quality, geographic and linguistic proximity and membership in a regional integration agreement play an important role for stability of global production systems. Our results highlight that the high sunk entry costs and the need for trust and reliability in global value chains are factors dissuading radical alterations in the network configuration.

本文重点研究了国际生产网络中贸易流动的生存能力，扩展了有限的经验证据。首先，我们强调这些贸易关系比最终货物贸易的寿命更长。其次，我们试图界定解释这一现象的因素。使用离散时间模型,控制难以察觉的异质性的存在,我们发现变量如贸易流的初始值,地理和产品多样化、制度质量、地理和语言距离和加入区域一体化协定了全球生产系统的稳定性起着重要的作用。我们的研究结果强调，全球价值链中的高沉没进入成本和对信任和可靠性的需要是阻止网络配置发生根本改变的因素。
