2022 Social Accounting Matrix for Ghana

The 2022 Ghana Social Accounting Matrix (SAM) follows IFPRI's Standard Nexus SAM approach, by focusing on consistency, comparability, and transparency of data. The Nexus SAMs available on IFPRI's website separates domestic production into 42 activities. Factors are disaggregated into labor, agricultural land, and capital, with labor further disaggregated across three education-based categories. The household account is divided into 10 representative household groups: Rural and urban households across per capita consumption quintiles. Nexus SAMs support the improvement of model-based research and policy analysis in developing countries and allow for more robust cross-country comparisons of national economic structures, especially agriculture-food systems.

2022年加纳社会核算矩阵（Social Accounting Matrix，SAM）遵循国际粮食政策研究所（International Food Policy Research Institute，IFPRI）的标准联结型社会核算矩阵框架，以数据的一致性、可比性与透明度为核心构建准则。IFPRI官网发布的联结型社会核算矩阵将国内生产活动划分为42个产业类别。生产要素被拆解为劳动力、农业用地与资本三类，其中劳动力进一步依据受教育程度划分为三个细分组别。住户账户划分为10个代表性住户群体，即按照人均消费五分位数划分的农村与城镇住户。联结型社会核算矩阵有助于优化发展中国家基于模型的研究与政策分析工作，同时能够实现更稳健的各国经济结构（尤其是农业-食品系统）跨国对比分析。
