2023 Social Accounting Matrix for Papua New Guinea

The 2023 Papua New Guinea 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.

2023年巴布亚新几内亚社会核算矩阵（Social Accounting Matrix, SAM）遵循国际粮食政策研究所（International Food Policy Research Institute, IFPRI）的标准联动型社会核算矩阵（Standard Nexus SAM）方法，以数据的一致性、可比性与透明度为核心构建准则。IFPRI官方网站发布的该类联动型社会核算矩阵将国内生产划分为42类生产活动。生产要素被细分为劳动力、农业用地与资本三大类别，其中劳动力进一步依据受教育程度划分为三个细分类别。住户账户被划分为10个代表性住户群组：依据人均消费五等分划分的农村与城镇住户群体。联动型社会核算矩阵可为发展中国家的模型导向型研究与政策分析提供优化支撑，并支持对各国国民经济结构（尤其是农业-食品系统）开展更为稳健的跨国比较分析。
