In this paper we investigate how structural patterns of international trade give rise to emissions inequalities across countries, and how such inequality in turn impact countries' mortality rates. We employ Multi-regional Input-Output analysis to distinguish between sulfur-dioxide (SO2) emissions produced within a country's boarders (production-based emissions) and emissions triggered by consumption in other countries (consumption-based emissions). We use social network analysis to capture countries' level of integration within the global trade network. We then apply the Prais-Winsten panel estimation technique to a panel data set across 172 countries over 20 years (1990-2010) to estimate the relationships between countries' level of integration and SO2 emissions, and the impact of trade integration and SO2 emission on mortality rates. Our findings suggest a positive, (log-) linear relationship between a country's level of integration and both kinds of emissions. In addition, although more integrated countries are mainly responsible for both forms of emissions, our findings indicate that they also tend to experience lower mortality rates. Our approach offers a unique combination of social network analysis with multiregional input-output analysis, which better operationalizes intuitive concepts about global trade and trade structure.
在本文中,我们研究国际贸易的结构模式如何导致各国间的排放不平等,以及这种不平等又如何反过来影响各国的死亡率。我们采用多区域投入产出分析来区分一个国家境内产生的二氧化硫(SO2)排放(基于生产的排放)和由其他国家消费引发的排放(基于消费的排放)。我们使用社会网络分析来衡量各国在全球贸易网络中的一体化程度。然后,我们将普莱斯-温斯顿面板估计技术应用于172个国家20年(1990 - 2010年)的面板数据集,以估计各国一体化程度与SO2排放之间的关系,以及贸易一体化和SO2排放对死亡率的影响。我们的研究结果表明,一个国家的一体化程度与这两种排放之间存在正的(对数)线性关系。此外,虽然一体化程度更高的国家对这两种形式的排放负有主要责任,但我们的研究结果表明,它们的死亡率也往往较低。我们的方法将社会网络分析与多区域投入产出分析进行了独特的结合,能更好地将关于全球贸易和贸易结构的直观概念付诸实践。
