Socioeconomic metabolism dynamics are relevant to identify (un)sustainable development pathways in different economies, particularly if the evolution of resource productivity of critical economic sectors can be quantified. This paper offers a four-step methodological framework to quantify these dynamics for an economy in a way that can be replicated for a series of years and countries. This methodological framework is based on the compilation of economic and physical flows in the form of input-output tables in a time series, making use of publicly available data. The data download and processing were automatized using Python, creating an expedited analysis process. The results characterize the flows through and within a country and allow the user to identify structural changes in the economy by tracking both monetary and physical flows for 17 material groups and up to 37 economic sectors. The application of the methodological framework is illustrated in a case study covering the 2008 economic crisis in Portugal, in which the socioeconomic metabolism, the underlying structural changes, and the corresponding environmental impacts are characterized. The use of this information for the design of decoupling policies is discussed, in view of promoting sustainable dematerialization during periods of economic prosperity.

分析国家社会经济新陈代谢动态的框架：葡萄牙案例研究

社会经济新陈代谢动态与识别不同经济体的（非）可持续发展路径相关，特别是如果关键经济部门的资源生产力的演变可以量化的话。本文提供了一个四步方法框架，以一种可以在一系列年份和国家中复制的方式量化经济的这些动态。该方法框架基于时间序列中以投入产出表的形式编制的经济和物理流量，并利用公开数据。使用 Python 自动下载和处理数据，从而加快分析过程。结果描述了流经和在一个国家内的流动，并允许用户通过跟踪 17 个材料组和多达 37 个经济部门的货币和实物流动来识别经济中的结构变化。该方法框架的应用在一个涵盖 2008 年葡萄牙经济危机的案例研究中得到了说明，其中描述了社会经济新陈代谢、潜在的结构变化和相应的环境影响。考虑到在经济繁荣时期促进可持续的非物质化，讨论了如何使用这些信息来设计脱钩政策。其中描述了社会经济代谢、潜在的结构变化和相应的环境影响。考虑到在经济繁荣时期促进可持续的非物质化，讨论了如何使用这些信息来设计脱钩政策。其中描述了社会经济代谢、潜在的结构变化和相应的环境影响。考虑到在经济繁荣时期促进可持续的非物质化，讨论了如何使用这些信息来设计脱钩政策。
