英文摘要：
The stability analysis of socioeconomic systems has been centered on answering whether small perturbations when a system is in a given quantitative state will push the system permanently to a different quantitative state. However, typically the quantitative state of socioeconomic systems is subject to constant change. Therefore, a key stability question that has been under-investigated is how strong the conditions of a system itself can change before the system moves to a qualitatively different behavior, i.e., how structurally stable the systems is. Here, we introduce a framework to investigate the structural stability of socioeconomic systems formed by the network of interactions among agents competing for resources. We measure the structural stability of the system as the range of conditions in the distribution and availability of resources compatible with the qualitative behavior in which all the constituent agents can be self-sustained across time. To illustrate our framework, we study an empirical representation of the global socioeconomic system formed by countries sharing and competing for multinational companies used as proxy for resources. We demonstrate that the structural stability of the system is inversely associated with the level of competition and the level of heterogeneity in the distribution of resources. Importantly, we show that the qualitative behavior of the observed global socioeconomic system is highly sensitive to changes in the distribution of resources. We believe this work provides a methodological basis to develop sustainable strategies for socioeconomic systems subject to constantly changing conditions.

中文摘要：
社会经济系统的稳定性分析一直集中在回答当一个系统处于给定的定量状态时，小扰动是否会将系统永久地推到不同的定量状态。然而，社会经济系统的数量状态通常会不断变化。因此，一个尚未被研究的关键稳定性问题是，在系统转变为一种性质不同的行为之前，系统本身的条件会发生多大程度的变化，即系统的结构稳定性如何。在这里，我们引入一个框架来研究社会经济系统的结构稳定性，该系统是由竞争资源的主体之间的相互作用网络形成的。我们将系统的结构稳定性衡量为与定性行为相容的资源分配和可用性条件范围，其中所有组成因素都可以在一段时间内自我维持。为了说明我们的框架，我们研究了一个全球社会经济体系的实证代表，该体系由国家共享和竞争作为资源代理的跨国公司而形成。我们证明了系统的结构稳定性与资源分配中的竞争水平和异质性水平成反比。重要的是，我们表明，所观察到的全球社会经济系统的定性行为对资源分布的变化高度敏感。我们认为，这项工作为在不断变化的条件下为社会经济系统制定可持续战略提供了方法学基矗
