中国直辖市社会核算矩阵数据集

SAM Table Dataset for Four Municipalities of China(2012, 2015)

可计算一般均衡模型(Computable General Equilibrium,CGE)是经济学的重要研究方法之一,近年来被广泛应用在关税、贸易壁垒、资源与环境等领域。本文基于投入产出理论,将我国41个产业部门与土地利用现状分类一级分类中5种国有建设用地相对应。根据最新的投入产出表,结合《中国国土资源年鉴》、《北京市统计年鉴》、《上海市统计年鉴》、《天津市统计年鉴》、《重庆市统计年鉴》等相关数据编制了2012-2015年北京、上海、天津、重庆四个直辖市的社会核算矩阵(SAM),并且根据直接交叉熵法进行了平衡。本数据集对构建城市用地CGE模型,研究城市用地及城市经济学相关问题能提供数据支持。

The Computable General Equilibrium(CGE) model is one of the important research methods in economics. In recent years, it has been applied widely in the fields of tariff, trade barriers, resources, and environment. The CGE model data come from the Social Accounting Matrix(SAM), which is based on an input-output table. However, most input-output tables are only prepared at national and provincial levels, which is not conducive to the study of urban problems using the CGE model. This paper, based on input-output theory, matches 41 industrial sectors in China to five types of state-owned construction land, including land for transport, in the first-level classification of landuse status. According to the latest input-output table, in combination with the "Land and Resources of China Yearbook", "Beijing Statistical Yearbook", "Shanghai Statistical Yearbook", "Tianjin Statistical Yearbook", "Chongqing Statistical Yearbook", and the Beijing, Shanghai, Tianjin, and Chongqing Social Accounting Matrix(SAM) in 2012–2015 are compiled and balanced using the direct cross-entropy method. This dataset can provide data support for the construction of an urban land use CGE model, and the study of urban land use and urban economics.
