The Social Accounting Matrix (SAM) is an extension of Input-Output tables that records macro and meso-economic accounts of a socio-economic system. Its main objective is to provide a comprehensive understanding of the interrelationships among different economic sectors and agents. The SAM can be used for various purposes, including economic analysis, policy evaluation, and economic modelling. It allows policymakers to make more informed decisions, understand potential consequences of different policy options and serve as the foundation for constructing Computable General Equilibrium (CGE) models.
The SAM for Germany is a comprehensive source of data that reveals the incomes and expenditures of 163 different production sectors, along with data on factors of production, households, corporations, government, and external accounts with the rest of the world. Additionally, it provides information on gross fixed capital formation, changes in inventories, and natural capital accounts. This SAM was compiled by extending the EXIOBASE Input-Output (IO) accounts with data from the Federal Statistical Office of Germany. Balancing items were also used to ensure that the Total Income and Total Expenditure of the main transactors are in balance.
社会核算矩阵(SAM)是投入产出表的延伸,记录了社会经济系统的宏观和中观经济账户。其主要目的是提供对不同经济部门和主体之间相互关系的全面理解。SAM 可用于多种目的,包括经济分析、政策评估和经济建模。它使政策制定者能够做出更明智的决策,了解不同政策选项的潜在后果,并作为构建可计算一般均衡(CGE)模型的基础。
德国的 SAM 是一个全面的数据来源,揭示了 163 个不同生产部门的收入和支出,以及生产要素、家庭、公司、政府和与世界其他地区的外部账户的数据。此外,它还提供了关于固定资产形成总额、库存变化和自然资本账户的信息。这个 SAM 是通过用德国联邦统计局的数据扩展 EXIOBASE 投入产出(IO)账户来编制的。平衡项也被用来确保主要交易方的总收入和总支出达到平衡。
