摘要翻译：
世界经济的日益一体化是经济危机在全球蔓延的关键因素之一，而世界经济在复杂的多层互动网络中组织起来。本文采用网络科学的方法对冲击在全球贸易-投资复合网络中的传播进行了量化。为此，我们提出了一个模型，该模型将描述经济困境如何在相关国家之间传播的易感-被感染-康复的流行病传播动态与描述这种经济困境在给定国家内传播的内部传染机制耦合起来。在地方一级，我们发现贸易和金融互动之间的相互作用影响着各国对冲击的脆弱性。在大尺度上，我们发现一个国家的冲击的相对幅度与其对整个经济系统的全球影响之间存在简单的线性关系，尽管内部传染的强度与国家有关，而国家间的传播动力学是非线性的。有趣的是，这种系统性影响可以根据层内和层间的尺度因子来预测，我们称之为网络乘数，这些因子与初始冲击的大小无关。我们的模型建立了一个定量框架，以压力测试单个国家和世界经济对不断蔓延的崩溃的稳健性。

英文摘要：
  The increasing integration of world economies, which organize in complex multilayer networks of interactions, is one of the critical factors for the global propagation of economic crises. We adopt the network science approach to quantify shock propagation on the global trade-investment multiplex network. To this aim, we propose a model that couples a Susceptible-Infected-Recovered epidemic spreading dynamics, describing how economic distress propagates between connected countries, with an internal contagion mechanism, describing the spreading of such economic distress within a given country. At the local level, we find that the interplay between trade and financial interactions influences the vulnerabilities of countries to shocks. At the large scale, we find a simple linear relation between the relative magnitude of a shock in a country and its global impact on the whole economic system, albeit the strength of internal contagion is country-dependent and the intercountry propagation dynamics is non-linear. Interestingly, this systemic impact can be predicted on the basis of intra-layer and inter-layer scale factors that we name network multipliers, that are independent of the magnitude of the initial shock. Our model sets-up a quantitative framework to stress-test the robustness of individual countries and of the world economy to propagating crashes.
