A 2007 Social Accounting Matrix for China

This paper documents a 2007 Social Accounting Matrix (SAM) for China. This SAM was constructed for the China CGE model to assess the impact of the 2008-09 global recession shocks and the Chinese government's stimulus policy on China's economic growth. The SAM is constructed using data from various sources including an existing input-output table, national accounts, government budgets, balance of payments, commodity exports and imports, labor employment and wage statistics, household expenditure surveys and agricultural production statistics. Cross-entropy estimation techniques are used to balance the SAM. This SAM is a detailed representation of China’s economy in 2007. It covers 61 production activities and commodity sectors, 4 types of factors (low skilled labor, skilled labor, capital, and land), and 2 representative household (rural and urban) groups. The structural characteristics of China’s economy presented in the SAM would be helpful to better understand the economic linkages. And the SAM also provides an ideal tool for economy-wide impact assessments, such as a SAM-based multiplier analysis and computable general equilibrium (CGE) modeling.本文记录了一份面向中国的2007年社会核算矩阵（Social Accounting Matrix, SAM）。该社会核算矩阵专为中国可计算一般均衡（Computable General Equilibrium, CGE）模型构建，用于评估2008-2009年全球经济衰退冲击以及中国政府刺激政策对中国经济增长的影响。本SAM通过多源数据整合构建，数据来源涵盖现有投入产出表、国民经济核算资料、政府预算数据、国际收支报表、商品进出口数据、劳动力就业与薪资统计、家庭支出调查以及农业生产统计等。研究采用交叉熵估计技术对该SAM进行平衡修正。该社会核算矩阵详细刻画了2007年中国的经济全貌，涵盖61个生产活动与商品部门、4类生产要素（低技能劳动力、高技能劳动力、资本与土地）以及2类典型家庭群体（农村与城镇家庭）。该SAM所呈现的中国经济结构特征，有助于更深入地理解经济系统内的各类关联机制；同时，该社会核算矩阵还为全经济范围的影响评估提供了理想工具，例如基于SAM的乘数分析以及可计算一般均衡建模。
